Calcified amorphous tumor of the heart (cardiac CAT) Inhibitors,research,lifescience,medical is a rare non-neoplastic cardiac mass that mimics malignancy on

imaging and can cause symptoms due to flow obstruction or embolization of calcific fragments. We report a 57-year-old female with multiple medical problems affected by cardiac CAT. The echocardiogram showed a 2 x 1.7 cm right atrial mass. Under Inhibitors,research,lifescience,medical the clinical diagnosis of cardiac myxoma, a mass resection was performed. Microscopic examination of the resected mass showed nodular calcified amorphous debris with admixed degenerated fibrin and focal chronic inflammation. At the 1-year follow-up, the patient was free of disease. We performed a literature review of 16 previously reported cases. Histologically, a cardiac CAT consists of calcification and eosinophilic amorphous material in the background of dense collagenous fibrous tissue. A review of these cases shows a wide range of age at diagnosis and slight female predominance. The patients are either asymptomatic at presentation or complain of shortness of breath. The

tumors have Inhibitors,research,lifescience,medical been found in all chambers of the heart, most commonly in the left ventricle. The sizes of the tumors range from 0.17 to 4 cm, with 62.5% of the tumors being mobile. Among the nine cases with documented follow-up study, all but one was free of disease and only one case of Inhibitors,research,lifescience,medical relapse was recorded. In 17-DMAG (Alvespimycin) HCl conclusion, cardiac CATs are frequently asymptomatic at presentation, size is equal to or less than 4 cm, they can be located in all four chambers and are usually mobile, and they may relapse when not completely excised. Keywords: calcified tumor, cardiac tumor, non-neoplastic Introduction Calcified amorphous tumor of the heart (cardiac CAT) is a rare non-neoplastic cardiac tumor that may be confused with a primary cardiac neoplasm, such as a cardiac myxoma, in clinical presentation. The tumor may be an incidental finding on imaging, or imaging may have been warranted due to symptoms of flow obstruction or embolization of calcific fragments. Here we report a case of a cardiac CAT and describe its characteristics. A review of the literature of 16 previously reported cases is also included.

En cas d’insuffisance rénale, la morphine et l’oxycodone ne sont pas contre-indiqués, mais les doses seront réduites et les prises espacées, surtout avec la

morphine dont les métabolites hépatiques 6-glucuro-conjugués, plus actifs que la morphine, risquent de s’accumuler. L’oxycodone a peu de métabolites actifs. Du fait de ses propriétés pharmacocinétiques (Modulators absence de métabolite actif), le fentanyl (par voie intraveineuse) représente une alternative à la morphine, notamment chez l’insuffisant rénal sévère (clairance de la créatinine < 30 mL/min) : sa titration Afatinib research buy devra être soigneuse [20]. Les AINS (anti-Cox1 et anti-Cox2) sont à éviter chez l’insuffisant rénal modéré et sont contre-indiqués chez l’insuffisant rénal sévère. Le tramadol est contre-indiqué

chez l’insuffisant rénal sévère. Elle n’a pas encore l’AMM en France, comme traitement antalgique. Cependant l’ANSM (ex Afssaps) dans des recommandations de juin 2010 « Douleur rebelle en situation palliative avancée chez l’adulte » [21], stipule qu’elle peut être envisagée en dernier recours, après une évaluation effectuée par une équipe spécialisée (soins palliatifs ou douleur). Elle ne doit selleck compound être prescrite qu’après rotation des opioïdes et traitement adjuvant bien conduit. La méthadone n’ayant pas de métabolites actifs, elle peut être utilisée en cas d’insuffisance rénale et de dialyse chronique. Le traitement doit être initié

par une équipe hospitalière spécialisée dans la prise en charge de la douleur ou des soins palliatifs Dichloromethane dehalogenase et formée à son utilisation. Le traitement par méthadone pourra être renouvelé par un médecin généraliste dans le cadre d’une rétrocession hospitalière. Il convient de se référer aux tableaux 4 et 5 des recommandations pour la pratique clinique de la Société française d’étude et de traitement de la douleur, publiées en 2010 sur « les douleurs neuropathiques chroniques : diagnostic, évaluation et traitement en médecine ambulatoire » (tableau VI) [13]. Malgré les recommandations disponibles en matière de traitement de la douleur du cancer, 10 à 15 % des patients auraient des douleurs dites rebelles en cours d’évolution (Meuser, 2001). On parle de douleurs cancéreuses rebelles lorsque les traitements spécifiques ne permettent pas d’améliorer le tableau clinique et lorsque les traitements symptomatiques conventionnels ne permettent pas un soulagement satisfaisant et durable de la douleur cancéreuse, ou bien occasionnent des effets indésirables intolérables et incontrôlables. En l’absence de consensus et d’arbre décisionnel quant à la place des thérapeutiques interventionnelles dans la douleur rebelle, les recommandations de bonnes pratiques de l’ANSM constituent un premier guide thérapeutique [21].

The patient was considered as stage IVB. Radiological and pathological examination revealed that the tumor was IPI-145 ic50 confined to the vaginal wall (T1) with no regional lymph node metastasis identified (N0). Distant metastasis to the liver was radiologically diagnosed (M1). The patient had a short course of treatment and died postoperatively. Figure 4 Radiographic image of Case 2. Pelvic ultrasound  shows hypoechoic predominantly endoluminal hetergenous  mass measuring

5×4.5×4.8 cm distending the upper vagina. Discussion Inhibitors,research,lifescience,medical Recent studies suggest that non-DES-associated and DES-associated PCCAV have different natural histories.6 The literature lacks information regarding the status of current or past prescription practices of DES in the Far East, Middle East and Africa, including countries such as Saudi Arabia, Yemen and Ethiopia. This lack of information has further limited our knowledge regarding its carcinogenic role in these regions. However according Inhibitors,research,lifescience,medical to the National Drug and Poison Information Center of the Saudi Food and Drug Authority, after a reported relationship of parenatally administered DES to adenocarcinoma, the use of DES during pregnancy was banned in the 1980s.8 There was only one case Inhibitors,research,lifescience,medical of DES-associated PCCAV reported in Saudi Arabia.9 Both patients in our study had no histories of DES exposure which was additionally supported

by the uneventful, normal obstetric histories of their mothers. Specifically Inhibitors,research,lifescience,medical there was no history of miscarriages or premature births which excluded any DES-induced influence. There was also no clinical evidence suggestive of other primary tumors to consider metastasis. A study of 28 cases6 and a few case reports of non-DES-associated PCCA of vagina1,6,10-12and cervix13,14 have been reported over the

past decade. Although DES has reportedly not been used as treatment for threatened abortion in Japan, Inhibitors,research,lifescience,medical at least nine cases of PCCA of the vagina and cervix have been reported over the past two decades.11 Abnormal vaginal bleeding, discharge, dyspareunia and vaginal mass are the most common presentations.1,6 Non DES PCCV shows a bimodal age distribution with the first peak observed at 26 years and the second at 71 years of age.1,6 A different subset of patients with non-DES-associated PCCAV in postmenopausal women and prepubertal girls has also been reported13 with a grave prognosis.6 Gross tumor size varies from microscopic to no 10 cm and is described as either a polypoid, nodular, flat or ulcerated mass. Microscopically this tumor show a predominantly tubulocystic pattern followed by solid and papillary patterns. However, a mixture of types is common. These structures are lined by cuboidal, hobnail or flat cells. Cytoplasmic clearing is due to the presence of glycogen. Cords having eosinophilic cytoplasm may also be present. Nuclear pleomorphism is variable with mitosis usually less than 10/10 high power fields.

In this sense, only two studies have described DNA vaccines for IPNV [17] and [18]. Atlantic salmon intramuscularly injected with selleck chemicals llc two plasmids (one with the long segment A ORF and the other with VP2 gene) showed a 84% of survival after IPNV challenge whist only 29% of the salmons vaccinated with the plasmid Libraries coding for VP2 gene alone survived [18], indicating the importance of other viral proteins apart from VP2 in the immunogenicity. This is also demonstrated by the finding that although most of the neutralizing antibodies are directed to VP2, there is also some immune reaction against VP3 and VP4 [19] and [20]. More recently,

a new DNA vaccine including the VP2 gene of IPNV has shown to up-regulate the expression of interferon (IFN) and IFN-related genes as well as the generation of specific antibodies in vaccinated brown trout [17]. However, further experiments are

still needed to develop an optimal DNA vaccine for IPNV and to elucidate the mechanisms used to induce the fish immune response. Considering this background, we have generated LY2109761 in vitro a DNA vaccine consisting of a plasmid encoding the IPNV polyprotein (pIPNV-PP) based on the long ORF of the segment A. We have evaluated the plasmid transcription in vitro and translation in cell-free transfection systems and in transfected fish cells. Through in vivo studies, rainbow trout specimens were intramuscularly injected with the plasmid and the effect on the innate (gene expression) and adaptive (neutralizing antibodies) immune system and the decrease of viral load upon a posterior challenge studied. Results are discussed trying to elucidate the protective mechanisms conferred by this vaccine until and the differences compared to other DNA vaccines and IPNV vaccines tested. Rainbow trout (O. mykiss) of approximately 6–8 cm (4–12 g) obtained from Centro de Acuicultura El Molino (Madrid, Spain) were maintained at the Centro de Investigación

en Sanidad Animal (CISA-INIA) laboratory at 14 °C and fed daily with a commercial diet (Skretting). Prior to the vaccination experiments, fish were acclimatised to laboratory conditions for 2 weeks. The Sp serotype of IPNV obtained from the American Type Culture Collection (ATCC VR 1318) was propagated in the RTG-2 (ATCC CCL-55) rainbow trout cell line. Cells were cultured at 20 °C in RPMI (Gibco) supplemented with penicillin (100 IU ml−1), streptomycin (100 μg ml−1) and 10% foetal calf serum (FCS, Gibco). Virus was inoculated on confluent RTG-2 in RPMI with antibiotics and 2% FCS at 14 °C. When cytophatic effect was extensive, the supernatant was harvested and centrifuged to eliminate cell debris. These supernatants were used for the experiments and titrated in 96-well plates according to Reed and Muench [21].

The baseline FRAX597 predictors were (i) age, gender, and duration of illness, (ii) symptomatic status assessed with the

expanded version of the CGI-Schizophrenia including an overall severity of illness score and 4 subscores for the severity of positive, negative, cognitive, and depressive syndromes, (iii) functional variables included the occupational/vocational status and independent living assessed in yes/no categories, (iv) subjective well-being assessed with the Inhibitors,research,lifescience,medical SWN. The early course of treatment predictors were early symptomatic, functional, and subjective well-being remission at 3 months. The course of treatment predictors were compliance with antipsychotic medication, (noncompliance was defined as missing ≥50 % of medication over at least 4 weeks) and comorbid substance use disorder (SUD) according to Diagnostic and Statistical Manual Inhibitors,research,lifescience,medical of Mental Disorders

(DSM-IV) criteria, categorized into (i) no SUD; (ii) remitted SUD (remission during follow-up with SUD at baseline); and (iii) persistent SUD. Lambert et al (unpublished data) found that 50 % of the patients achieved symptomatic remission and about 40 % subjective well-being remission, whereas only Inhibitors,research,lifescience,medical one third sustained functional remission. Including symptomatic and functional criteria, 19 % achieved complete remission in the SOHO study; following the consensus statement including the subjective quality of life, remission Inhibitors,research,lifescience,medical rate decreased to 14 %. It is of particular interest that 32 % of all patients achieved none of the three remission criteria. First antipsychotic treatment proved to be a predictor of all remission criteria. Similarly to the study by Robinson,52 the functional remission criterion of 24.5 % was the main barrier in achieving complete remission. Consistent with previous studies,52,56 early remission within the first 3 months predicted all remission

Inhibitors,research,lifescience,medical criteria including complete remission. Therefore, early detection others of incomplete remission or treatment resistance and subsequent treatment adaptation are mandatory in the treatment of multiple-episode patients as well as first-episode patients.61 Lambert et al found specific predictors of remission components in the SOHO analysis. Persistent SUD when compared with no SUD was associated with a decreased probability of symptomatic remission, while baseline SUD was not found to have significant influence on symptomatic remission, consistent with previous findings.60 Similar to findings from many previous studies, medication noncompliance was associated with symptomatic nonremission. Conclusion For a long period, many psychiatrists believed that they knew their patients well enough not to need additional self-ratings by the patients.

Cytological detection of high grade this website dysplasia is the optimal detection point for providing early intervention, either surgically or with cyst ablation therapy (28),(33). Distinguishing intermediate grade dysplasia (e.g. moderate dysplasia (12) or borderline malignancy (34))

from high grade dysplasia (e.g. carcinoma in-situ (12)) is not only a challenge for histological analysis, but is especially a challenge for cytological analysis (35). The heterogeneity of the cyst lining typical of most mucinous cysts may cause the cells in the cyst fluid to under-estimate the final histological grade (27), and cellular degeneration coupled with a lack of standardized criteria and pathologist’s experience Inhibitors,research,lifescience,medical with these types of specimens contributes to the poor performance

Inhibitors,research,lifescience,medical of cytological analysis in many cases (personal experience). That being said, the recognition of high-grade dysplasia on cytological analysis is a powerful finding for early detection of cancer (28),(33), and if you don’t look, you won’t find it. Aside from CEA, amylase and cytological analysis, the future is looking to pancreatic cyst fluids as a rich source of DNA for molecular analysis. There is an explosion of research in this area which is beyond the scope of this editorial. In brief and to the best of our knowledge, no established molecular test is specific for the detection of malignancy. A KRAS mutation Inhibitors,research,lifescience,medical supports a mucinous etiology, but is inaccurate in distinguishing IPMN from MCN or in determining malignancy (36),(37). The very recent report of GNAS mutation analysis shows promise in distinguishing mucinous from serous cysts and IPMN from MCN, but, again, is not a mutation that correlates with histological grade (38). While further development of more specific markers of cyst type and biological behavior Inhibitors,research,lifescience,medical is awaited, imaging and cyst fluid analysis, including CEA, amylase and cytology, currently offer the best means of accurately assessing pancreatic cysts preoperatively. If cyst fluid analysis does Inhibitors,research,lifescience,medical not support a mucinous etiology on the one hand, or high grade dysplasia in a mucinous cyst on the other, conservative patient management is a viable alternative in asymptomatic

patients without high risk imaging features, especially in an unsuitable surgical candidate. during Footnotes No potential conflict interest.
Within the last year more than 42,000 people in the United States were newly diagnosed with pancreatic cancer, which makes it the fourth leading cause of cancer mortality (1). A majority of patients diagnosed with pancreatic cancer are considered inoperable at the time of the diagnosis due to locally advanced disease or the presence of metastasis, and the efficacy of systemic chemotherapy is limited (2). The prognosis for these patients is one of the worst among all cancers: according to EUROCARE study, based on over 30,000 cases, overall survival at 1,3 and 5 years was 16%, 5% and 4%, respectively (3).

Transverse sections (40 μm thick) were obtained with a cryostat (Leica, Heidelberg, Germany) individually placed on 96-well plates in Olmos solution and stored at −20°C. The sections were distributed in 50 series of five sections each, and each series was selleck screening library prepared for immunohistochemical analysis by blocking with 10% bovine serum, 0.3% Triton X-100 in tris-buffered saline for 1 h at room temperature, followed by incubation

with different combinations of up to three primary antibodies against synaptotagmin (clone Mab48, Developmental Studies Hybridoma Bank, IA), nitrotyrosine (Millipore, Bedford, MA), human HCA-ABC antigen (MHC-I, DAKO, Glostrup, Inhibitors,research,lifescience,medical Denmark), MHC-II-APC (eBiosciences, SanDiego, CA), Iba1 (Wako, Tokyo, Osaka, Japan), sigma 1 Receptor (Sig1-R, Santa Cruz Biotechnologies, Santa Cruz, CA) and ChAT (Millipore) Inhibitors,research,lifescience,medical overnight at 4°C. After washes, sections were incubated for 1 day at 4°C with biotinylated secondary antibodies (Vector, Burlingame, CA, 1: 200) with Cy-2, Cy-3, or Cy-5 conjugated donkey anti-rabbit, anti-mouse, or anti-goat IgGs antibodies

(Jackson Immunoresearch, Inhibitors,research,lifescience,medical West Grove, PA, 1:200). Slides were counterstained with DAPI (4′,6-diamidino-2-phenylindole) (Sigma, St Louis, MO, 1: 1000) and mounted with Fluoromount (SouthernBiotech, Birmingham, AL). Omission of the primary antibodies resulted in no detectable staining. At lumbar levels, the analysis was focused in MNs from L4–L5 segments that provide innervation to hindlimb muscles. Sections from different time points of transgenic and Inhibitors,research,lifescience,medical control animals were processed in parallel for immunohistochemistry and data represent an accumulation of different day performances. Confocal microscope Inhibitors,research,lifescience,medical examinations were performed with a Leica TCS SP2 AOBS laser scanning confocal system (Leica). All MNs were analyzed in a z-plane containing the nucleus and captured using the FV10-ASW 1.7 Viewer software. Confocal images were obtained

using two separate photomultiplier channels, either concurrently or in separate runs, and were separately projected and merged using a pseudocolor display showing green for Cy2, red for Cy3, magenta for Cy5, and blue for DAPI. When densitometric analysis was performed, images of the ventral area of the spinal cord were taken under the same exposure time, sensibility, and resolution for each marker analyzed, SB-3CT with the aid of a digital camera (Olympus DP50) attached to the microscope (Olympus BX51). The microphotographs were transformed to a gray scale and analyzed using ImageJ software. Immunoreactivity was assessed by calculating the integrated density, after defining a threshold for background correction. The integrated density of a region of interest (ROI), defined as the area above the threshold for the mean density minus the background, was measured.

The different pattern of density change noted in depression in the hippocampus in contrast to frontal cortical areas may be related to a unique reduction in neuropil

in the hippocampus in depression. Neuropil consists of the lattice of glial cells and their processes, dendrites, and proximal axons surrounding neuron cell bodies. The hypothesis of neuropil reduction in the hippocampus in MDD is supported by other postmortem studies revealing a decrease in click here dendritic spine density on neurons and diminished arborization of apical dendrites in the Inhibitors,research,lifescience,medical subiculum in a small group of mixed subjects with bipolar disorder or depression37 and decreased levels of synaptic proteins found in CA4 in BPD.38 Thus, the diminished volume of the hippocampus noted by some in depression Inhibitors,research,lifescience,medical may be critically determined by a loss in neuropil including dendritic branching, dendritic spine complexity, and glial processes. The expression of brain-derived neurotrophic factor (BDNF) has been measured in the hippocampus of subjects with depression, and alterations in these factors might be related to changes in cell density and volume

in depression. There is preliminary evidence that BDNF in the human hippocampus may be regulated by chronic treatment with antidepressant medications. In an irnmunohistochemical study of subjects with MDD and others Inhibitors,research,lifescience,medical with BPD or schizophrenia, the immunoreactivity of BDNF, as

measured by optical density, is upregulated in the dentate gyrus and hilus only in subjects taking antidepressant medications (regardless of psychiatric diagnosis).39 Chen et al39 provide the first, evidence beyond Inhibitors,research,lifescience,medical rodent studies that chronic antidepressant drugs upregulate the expression of BDNF in the human hippocampus. In a recent study, Dwivedi et al40 observed a significant reduction in mRNA and protein levels of BDNF in hippocampus as well as dorsolateral prefrontal cortex in suicide Inhibitors,research,lifescience,medical victims with either MDD or other psychiatric disorders. In the Dwivedi et al40 study, the decrease in expression however of BDNF occurred regardless of antidepressant treatment. It remains to be determined whether alterations in BDNF are related to increases in the packing density of neurons in the hippocampal formation or prefrontal cortex. The different, pattern of neuronal pathology in the frontal cortex (decrease in density) and hippocampus (increase in density) suggests unique involvement of these brain regions in the neuropathology of depression. Other evidence of dissimilarities between prefrontal cortex and hippocampus has been reported in MDD.41-43 Successful clinical treatment (or even the use of placebo) in depression was associated with an increase in metabolism in prefrontal cortex and a decrease in metabolism in hippocampus.

3A,

each vaccination approach induced strong antibody responses against RABV G as expected since RABV G was present in each immunogen. Either a single dose or two doses of INAC-RV-HC50 Selleck Erlotinib induced botulinum HC50-specific antibodies, and interestingly, combined administration with INAC-RV-GP resulted in a slightly stronger HC50-specific response (Fig. 3B). Finally, analysis of the GP-specific antibody response indicated that single or boosted immunization with INAC-RV-GP induced strong immunity as expected (Fig. 3C). Importantly, co-administration of INAC-RV-GP and INAC-RV-HC50 induced antibody levels that were nearly identical to INAC-RV-GP immunization. These results indicate that a potent multivalent response can be induced by this inactivated vaccination platform. Co-immunization with three antigens, RABV G, HC50, and ZEBOV GP resulted in no decrease in antibody response against each individual immunogen. There is a possibility that some members of the target population for an Ebola vaccine such as lab workers or first responders may be previously vaccinated with the currently approved RABV vaccine and thus have pre-existing immunity to RABV. This pre-existing immunity might interfere with induction of the EBOV GP-specific antibodies upon immunization with INAC-RV-GP.

Therefore, we sought to determine in the mouse model if prior vaccination with a RABV vaccine would inhibit the induction of GP-specific antibodies (Fig. 4). Groups of five mice

FXR agonist were immunized once on day Resveratrol 0 with vehicle, 10 μg INAC-RV-HC50 or INAC-RV-GP. A fourth group was immunized with 10 μg inactivated INAC-RV-HC50 on day 0 followed by 10 μg inactivated INAC-RV-GP on day 28. Four weeks after immunization, serum from each group was assayed by ELISA against (A) RABV G, (B) HC50, and (C) EBOV GP. As expected, each vaccination approach induced strong antibody responses against RABV G (Fig. 4A) and vaccination with INAC-RV-HC50 or INAC-RV-HC50 followed by INAC-RV-GP induced potent HC50-specific antibodies (Fig. 4B). Interestingly, vaccination with INAC-RV-HC50 followed by INAC-RV-GP induced similar levels of GP-specific antibodies to vaccination with INAC-GP alone (Fig. 4C). These results indicate that immunization with INAC-RV-GP can induce GP-specific antibodies in the presence of pre-existing RABV immunity. The presence of a potent RABV G-specific antibody response at day 28 prior to immunization with INAC-RV-GP was confirmed (data not shown). Several vaccination strategies have been demonstrated to confer protection from Ebola hemorrhagic fever in macaques, including DNA vaccines, inhibitors virus-like particles, or recombinant viruses expressing GP including adenovirus, vesicular stomatitis virus, or paramyxoviruses [2], [4], [5], [6], [7], [8], [24], [25], [26], [27] and [28].

The GIST decreased from its initial size of 13.5 x 8.7 cm in November 2008 to 9.0 x 6.0 cm in January 2009. The selleck chemical primary tumour continued to decrease in size from 6.3 x 3.7 cm in June 2009 to 5.2 x 3.5 cm in November 2009. Figure 4 CT scan of the abdomen following treatment with imatinib mesylate revealing a reduction of GIST (top arrow). The colon mass is now visible (bottom arrow)

The CT scan in November 2009 revealed the presence of a colonic mass with mesenteric lymphadenopathy. The presence of the newly identified mass was confirmed on colonoscopy, Inhibitors,research,lifescience,medical which revealed the presence of an intraluminal mass at 80 cm from the anal verge. Biopsy of this lesion revealed an invasive, moderately differentiated adenocarcinoma of colonic origin. After discussion at tumor board, a Inhibitors,research,lifescience,medical decision was made to resect the primary colonic mass as well as the primary GIST. In December 2009, the patient underwent a left hemicolectomy in addition to resection of the

primary GIST, which originated in the small bowel. The pathology Inhibitors,research,lifescience,medical of the colonic mass revealed a moderately differentiated adenocarcinoma with 7 out 12 lymph nodes involved. The small bowel pathology revealed a spindle cell lesion consistent with a GIST, which was positive for CD117 and CD34. The Ki67 stain showed positivity in less than 1% of tumour cells. The mitotic count was less than 1 per 50 High Power Fields (HPF). The tumour showed large hypocellular areas of hyalinization, an area of Inhibitors,research,lifescience,medical necrosis, and several areas of hemorrhage as well as a focal hemangiopericytoma-like pattern, consistent with treatment (imatinib mesylate) effect. Of note, the laboratory findings did not include a preoperative CEA, however, a CEA level was drawn shortly after the surgery, measuring 2.5 ug/L. She subsequently received 12 cycles of modified FOLFOX-6 chemotherapy while remaining on imatinib for her metastatic

GIST. She did not experience any unexpected toxicity from either the imatinib or chemotherapy and remains well with continued regression Inhibitors,research,lifescience,medical of her liver metastasis (GIST). Case 2 A 61-year-old Caucasian gentleman presented with a change in bowel habits and rectal bleeding in March 2009. He reported no associated anorexia or weight loss. Colonoscopy and biopsy revealed an adenocarcinoma at the splenic flexure. A staging CT scan also revealed a few subcentimeter lymph nodes and a 5 cm mass at the gastrohepatic ligament also until suspected to be an enlarged metastatic lymph node (Fig 5). Figure 5 CT scan demonstrating a mass later confirmed to be a primary gastric GIST In May 2009, at the time of surgery, the gastrohepatic mass was resected. Once confirmed on a frozen section to be a spindle cell tumour consistent with a GIST, a partial gastrectomy was performed. During the same operation, the patient also underwent a left hemicolectomy.
