Introduction. Meckel?s diverticulum is the most common congenital anomaly of the gastro intestinal tract, present in about 2% of population. Case Outline. The article presents the case of a 44-year-old otherwise healthy man with anemia, who was diagnosed lower gastrointestinal bleeding. An abdominal CT scan revealed a clearly demarcated solid tumor in hypogastric region, measuring 65 ? 45 mm. A laparotomy through lower midline incision was performed. A surgical resection of a lesion of a Meckel?s diverticulum was carried out and a final diagnosis of gastrointestinal stromal tumor was made. The patient made an uneventful recovery. Conclusion. The preoperative diagnosis of a complicated Meckel?s diverticulum may be challenging. CT is usually an adequate method to diagnose tumors arising from Meckel?s diverticulum.

Abdominal Ct Scan

The article presents a case report of a patient with an intramural gastric hematoma. Diagnostic examinations were suggestive of a suspected gastrointestinal stromal tumor Normal image was observed in gastroscopic examination while abdominal CT scan revealed a nodular lesion along the greater curvature of the stomach extending from the posterior wall and adjoining the pancreas and the spleen. The patient was qualified for surgical treatment. Laparotomy was performed followed by total gastric resection and Roux-en-Y reconstruction of the gastrointestinal tract. Post-operative histopathological examination revealed the presence of an extensive hematoma penetrating the perigastric fat tissue along with numerous hemosiderinophages and segmental indicators of formation of inflammatory granulation tissue suggestive of a chronic nature of the lesion. Immunohistochemical GIST assays (CD117, DOG-1, CD34, CD31, SMA, S-100, CKAE1/AE3, Ki-67) were negative. No complications were observed in the post-operative course. Patient is subject to continued follow-up and observation. Follow-up gastroscopy and abdominal CT scan performed 6 months after the surgery revealed an unremarkable image.

Vague Abdominal Pain

Extramedullary haematopoiesis (EMH) is defined as haematopoiesis occurring in organs outside the bone marrow. The liver is one of the rare sites of EMH, and to the best of our knowledge, a few cases of adult EMH of the liver have been reported in the last 20 years. Here, we reported the case of a 68-year-old man with a known history of myelofibrosis presented with vague abdominal pain. An abdominal CT scan showed a hypoattenuating periportal mass encasing the portal vein. The final diagnosis of EMH was made through the histopathological examination. This is a rare presentation of EMH, which may be easily mistaken for other pathologies such as metastases. Familiarity with this type of presentation aids in correctly diagnosing it in an appropriate clinical setting.

Background: Endoscopic ultrasonography(EUS) allows high-resolution demonstration of the entire gut wall. The aim of the study was to clarify the usefulness of the EUS in differential diagnosis of upper gastro-intestinal subepithelail lesions(SEL). Methods: From September 1998- March 2005, EUS was performed in 1600 patients. Among them, in 206pts (13%), this examination was carried out due to previous upper endoscopy, which revealed the suspicion to SEL or extraluminal compression. We studied the location, the size, echo pattern and originating layer of SEL. The results were compared with CT, angiography and operation with histology when possible. All EUS examinations were performed using Olympus GIF-130 videoecho-endoscope with 7,5/12MHz switch able radial probe. Results: EUS accuracy in separating intramural masses from extraluminal compression was 96 %( 44/46). Among 160 pts with true SEL, in 95(59, 3%), EUS revealed the existence of a stromal tumor arising from muscularis propria (92) or muscularis mucosae (3). The size of the tumor varied from 5-75mm; depth: 8- 40mm. 33 patients were operated on. In 14/16(87%), the EUS diagnosis of benign stromal tumor was confirmed on operation. In 18/19(95%), EUS correctly disclosed the malignant tumor. EUS accuracy in predicting malignancy was 91,5%(32/35). Findings suggestive for malignancy were: size 40mm; inhomogenicity with microcysts and irregular outer margin. In 12 pts, EUS revealed lypoma. Aberrant pancreas was correctly diagnosed in all 22pts. In 16 persons, EUS disclosed submucosal cysts: 6 of them were operated on and EUS diagnosis was confirmed in all. In 10 patients EUS visualized varices. The finding was confirmed on angiography. Conclusion: The EUS appears to be very effective in differential diagnosis of SEL in upper gastro-intestinal tract. Tumor size greater than 40mm, inhomomogenous echo pattern and irregular outer margin are very suggestive for malignancy.

SummaryGastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal (GI) tract (3). A 68-year-old male patient was referred to our hospital with complaints about feeling pressure in the thorax and heavy sweating for over 2 years. Abdominal CT showed a pathological formation approximately 21 cm × 15cm × 15 cm in size. The stomach was compressed and dislocated by the tumor. The total gastrectomy Roux modification was performed. The tumor grows from the back wall of the stomach; the tumor is not grew into the mucosa. We made a final diagnosis of an extra luminal GIST of the stomach - pT4N0M0G1R0 stage II. There was no evidence of disease recurrence six months after surgery.

Neuroendocrine Cancers

Gastric neuroendocrine tumors (NETs) are rare lesions that arise from enterochromaffin-like cells of the gastric mucosa. Gastric NETs are classified into 3 types of NETs and poorly differentiated neuroendocrine cancers. Most gastric NETs usually present as hemispherical, yellowish, polypoid lesions with a central depression and often as subepithelial tumors (SETs) because they are confined within the submucosal layer. Here, we report a case of gastric NET presenting as SET mimicking a gastrointestinal stromal tumor (GIST). Endoscopy revealed a 2.3-cm-sized SET with intact surface mucosa, and endoscopic ultrasonography showed a homogeneous hypoechoic lesion with a well-circumscribed margin. Typical features of gastric NET, such as yellowish mucosal changes or central ulceration, were not observed. GIST was suspected, and a laparoscopic wedge resection was performed. The final diagnosis was gastric NET with grade 2 differentiation.

Abstract Objectives Microcystic stromal tumor (MST) of the ovary is an extremely rare subtype of sex cord-stromal ovarian tumor with characteristic microcystic features and stromal tumor immunophenotype. First described as a distinct ovarian neoplasm in 2009, fewer than 30 cases of MST have been reported worldwide. Methods We present a 65-year-old patient who underwent a hysterectomy and bilateral salpingo-oophorectomy for endometrial carcinoma and an enlarged right ovary detected by an abdominal CT scan. Results Grossly, the 3.6-cm ovarian mass had a smooth, firm external surface and clear demarcation from the adjacent ovarian parenchyma. Sectioning of the mass revealed solid, tan-white cut surfaces. The gross appearance of the contralateral ovary was unremarkable. Microscopic examination of the hysterectomy specimen confirmed FIGO grade 1 endometrial adenocarcinoma, endometrioid type. Stromal hyperthecosis was present in both ovaries. Unique to our case, the ovarian mass was composed of a prominent hyalinized fibrous stroma with occasional scattered nodules of small to medium cells with vacuolated cytoplasm, bland chromatin, inconspicuous nucleoli, and sparse mitotic activity. Characteristic microcystic spaces were present. The cells within these microcystic nodules were positive for β-catenin (nuclear), CD10 (membranous), and cyclin D1 (nuclear). Immunohistochemical stains for calretinin, CD56, CD99, cytokeratin AE1/AE3, EMA, inhibin, and WT-1 were negative. Conclusion The combined histologic and immunohistochemical properties of this tumor are most consistent with MST of the ovary. While the clinical behavior of this new entity appears to be benign, reported cases are limited and further investigation is needed. This report highlights a histologically unique case of MST of the ovary.
