1/22. Malignant schwannoma of the stomach in a patient with von Recklinghausen's disease.

    A patient with von Recklinghausen's disease died with a malignant schwannoma of the stomach and was found at autopsy to have neurofibromatosis of the gastrointestinal tract, a plexiform neurofibroma of the myocardium and a phaechromocytoma. Malignancy of the gastrointestinal tract in von Recklinghausen's disease is rare, and this case highlights the difficulties in histological diagnosis of malignant nerve sheath tumours.

2/22. Cytomorphology of gastrointestinal stromal tumor: diagnostic role of aspiration cytology, core biopsy, and immunochemistry.

    gastrointestinal stromal tumors (GISTs) comprise a heterogeneous group of neoplasms of the gastrointestinal tract previously referred to as leiomyomas, leiomyosarcomas, or schwannomas. GISTs derive from the interstitial cell of Cajal and, in addition to variable expression of smooth muscle and neural markers, they characteristically express CD34 and CD117. To our knowledge, the cytologic appearance of gastric neoplasms designated as GISTs has never been reported. We illustrate the fine-needle aspiration (FNA) cytology findings of a gastric stromal tumor having spindle cells with delicate cytoplasm and prominent nuclear palisading. Consistent core biopsy and immunochemistry findings further supported the diagnosis of GIST. Pathologic evaluation of the resected tumor confirmed the cytologic diagnosis. In the appropriate clinical and radiologic setting, a confident diagnosis of GIST can be established by FNA cytology and core biopsy. The roles of immunochemical stains and other ancillary techniques in reaching the correct diagnosis are addressed.

3/22. Gastric schwannoma found incidentally 19 years after a horizontal gastroplasty for morbid obesity.

    This report represents the first known case of a gastric schwannoma in a patient subsequent to a gastric stapling and partitioning procedure for morbid obesity. The submucosal tumor found in the collapsed distal portion of the stomach was merely an incidental finding and it appeared that all of the patient's ongoing symptomatology (nausea and vomiting after meals) was a reflection of the chronic obstruction that was present at the gastric partitioning staple-line. No correlation between gastric stapling and partitioning and the development of gastric schwannoma is known or is suggested in this report.

4/22. Gastric schwannoma presenting as gastric polyp with gastrointestinal bleeding.

    Benign neurogenic tumors of stomach are the commonest of all nonepithelial tumors of the stomach, but solitary gastric schwannomas are rare. We report a 58-year-old man with gastric schwannoma presenting as fundal polyp and upper gastrointestinal bleeding. Endoscopic polypectomy was done.

5/22. Case report: gastric schwannoma: MRI findings.

    MRI features are described in a case of gastric schwannoma. A large, discretely marginated, multilobular mass was seen adjacent to the gastric antrum with the epicentre of the mass in the gastrocolic ligament. The overall signal pattern was low on T(1) weighted images and moderate to markedly elevated on T(2) weighted images. Post-gadolinium sequences demonstrate slow but fairly uniform enhancement throughout the mass.

6/22. Gastric schwannoma as a rare differential diagnosis of pleural effusion.

    We report a case of solitary gastric schwannoma that initially manifested with recurrent left pleural effusion caused by an inflammatory reaction. A 75-year-old female was primarily admitted with progressive dyspnoea and left sided effusion. history as well as clinical examination, gastroscopy, computed tomography (CT) and transabdominal ultrasound of the abdomen suggested the diagnosis of a benign tumour of the stomach. The tumour was resected and a fundectomy with a security distance of 3-5 cm performed. Histological assessment revealed a large intramural schwannoma of the gastric wall, arising from the submucosal layer. There was no evidence of malignancy. During a three year follow-up the patient has not shown any evidence of relapse or pleural effusion. This is a very rare manifestation of this benign tumour, representing a rare differential diagnosis in a case of left sided pleural effusion.

7/22. A functioning pleomorphic carcinoma of the thyroid.

    A metastasizing functioning pleomorphic carcinoma of the thyroid displayed a morphologic piture ranging from follicular to sarcomatous and carcinoid-like patterns. Spindle-cell elements were believed to be the result of metaplasia of the follicular epithelium. Development of carcinoid-like lesions in the secondary deposits of tumour supported the contention that so-called parafollicular or c-cells may be a phenomenon of metaplasia and not a histologic entity. The tumour was associated with a chromophobe adenoma of the pituitary and a benign schwannoma of the stomach. Clinically the patient did not show any other endocrinologic abnormalities and lived for 4 years from the time of diagnosis of the thyroid tumour.

8/22. Gastric schwannoma.

    Gastrointestinal mesenchymal tumors are a group of tumors originated from the mesenchymal stem cells of the gastrointestinal tract, consisting of gastrointestinal stromal tumors (GIST), leiomyomas or leiomyosarcomas or schwannomas. Gastric schwannoma is a very rare gastrointestinal mesenchymal tumor, which represents only 0.2% of all gastric tumors and 4% of all benign gastric neoplasms. We report a 24-year-old girl who suffered from an episode of upper gastrointestinal bleeding. The endoscopic examination showed a round submucosal tumor with a central ulceration and bleeding over the high body of the stomach. Surgical resection of the tumor was performed. The pathological examination revealed a picture of spindle cell tumor that was strongly positive for S-100 protein stain, and non-reactive for CD34, CD117, actin, HHF-35, desmin, melan-A and HMB-45, consistent with gastric schwannoma. The literature is reviewed.

9/22. The unique simultaneous occurrence of granular cell tumor, gastrointestinal stromal tumor, and gastric adenocarcinoma.

    Granular cell tumors are generally benign oncocytoid lesions of schwannian origin that are often incidental findings in many locations. gastrointestinal stromal tumors occur in older adults and express the c-Kit protein (CD117). Both of these tumors have been described in association with many other entities; however, they have never been reported to occur jointly. This report is prompted by the simultaneous appearance of 2 granular cell tumors, a gastrointestinal stromal tumor, and a gastric adenocarcinoma in a 65-year-old woman with a history of breast carcinoma and granular cell tumor. To our knowledge, this is the first case report of these tumors occurring simultaneously.

10/22. Gastric schwannoma after Nissen fundoplication. A rare complication?

    Surgical repair of an hiatal hernia results in changes in the local anatomy of the cardia and fundus that may be difficult to interpret by radiological examination. endoscopy can clarify the radiological changes resulting from surgery, such as pseudodiverticula and pseudotumors, and, when conducted as part of the routine follow-up program, may reveal uncommon complications.
