Abstract Gastrointestinal stromal tumors are CD117 (c-Kit)–positive mesenchymal neoplasms with histologic and ultrastructural features of the interstitial cell of Cajal. While tumors outside of the gastrointestinal tract have been described, to our knowledge the case we present is the first such case in the vagina. We describe a 75-year-old woman with a recurrent vaginal gastrointestinal stromal tumor without apparent rectal involvement. This tumor was characterized by short intersecting fascicles of spindled cells, focal necrosis, and 12 to 15 mitoses per 50 high-power fields. Immunohistochemistry revealed diffuse cytoplasmic positivity for CD117 (c-Kit), CD34, vimentin, and h-caldesmon. Tumor cells were negative for S100, desmin, actin, and CAM 5.2. The differential diagnosis in this case included a vaginal smooth muscle tumor. While histologically similar to a smooth muscle neoplasm, the immunohistochemical profile ruled out smooth muscle differentiation. Gastrointestinal stromal tumor should be considered in the differential diagnosis of vaginal mesenchymal neoplasms.

Gastric Mass

Gastric schwannomas are rare mesenchymal tumors that arise from the nerve plexus of gut wall. They present with nonspecific symptoms and are often detected incidentally. Preoperative investigation is not pathognomic and many are therefore misdiagnosed as gastrointestinal stromal tumors. We report a rare case of a 37-year old woman who underwent laparotomy for complex bilateral ovarian cyst with resection of gastric-gastrointestinal stromal tumor preoperatively, but confirmed to have a gastric schwannomas postoperatively. This case underscores the differential diagnosis of submucosal, exophytic gastric mass as schwannoma.

Objective : This article objective is to describe a woman with extra gastrointestinal stromal tumor (extra GIST) in ovary; Method : A case report and literature review; The author reports a woman 54 years old with complaints of swelling in the abdomen. Tumors suspected originate from ovary with an extension to abdominal wall. The patient had history of previous ovarian tumor surgery with pathological anatomy diagnosis was thecoma. Working diagnosis of the patient was residif ovarian malignancy and then suboptimal debulking was performed. Microscopically, ovarian tumors appear cellular and diffuse, partially arranged fascicles. Cells with rounded-spindle nuclei, mitosis ≥ 4 per 10 HPF. The conclusion was malignant thecoma which metastasizes to peritoneum and omentum. Differential diagnosis were GIST and leiomyosarcoma. Immunohistochemistry examination was performed with  Calretinin and CD117 to rule out the differential diagnosis. Calretinin were negative  and CD117 were strongly positively smeared. Based on the morphology and positive CD117 results, diagnosis was extra GIST of ovary.; Conclusion: Extra GIST in the ovary is an unusual location so that it can be misdiagnosed as a gynecological disorder. The differential diagnosis at this location is quite limited including thecoma, fibrothecoma and leiomyosarcoma.Keywords: extra gastrointestinal stromal tumor, ovary, thecoma
