Gastrointestinal stromal tumors are the most common mesenchymal tumors of the gastrointestinal tract. These tumors are present in almost all case mutations of KIT-CD117. When located in different places other than the gastrointestinal tract they are called extragastrointestinal stromal tumors (EGISTs). We present the case of a 70-year old patient with abdominal pain. Computed tomography (C/T) and ultrasound (U/S) indicated the existence of a hypoechoic enlarged 9.6 x 10 cm uterus due to leiomyoma. The clinical condition of the patient deteriorated and obtained the characteristics of an acute abdomen. The patient underwent urgent exploratory laparotomy, which revealed the incidental existence of a large tumorous formation in the pouch of Douglas. A total abdominal hysterectomy, bilateral ovarectomy, omentectomy, and tumor resection from the rectouterine pouch were performed. Histology analysis confirmed the diagnosis of a malignant EGIST. EGISTs are infrequent in pelvis. In our case, pelvic EGIST led to an acute pain symptomatology obtaining characteristics of invasive uterine leiomyosarcoma. Pelvic imaging with classical methods of U/S and C/T may lead to confusion and false diagnosis. To the best of our knowledge, this is the first case report about an EGIST located in the rectouterine pouch of Douglas leading to acute abdomen symptomatology.

The authors report on a case of voluminous perforated gastrointestinal stromal tumor (GIST) of small intestine and make a review to the light of most recent clinicopathologic advancements. The first clinical manifestation as acute abdomen due to their perforation extremely rare. Gastrointestinal stromal tumor (GIST) represent a rare group of multiform tumors with various biological behaviour. Were identified in the past as leiomyomas, leiomyosarcomas or leiomyoblastomas, has been reclassified on immunochemical features, with a positive expression of Kit (CD117 antigen). Traditionally the prognostic factors of these tumour are: mitotic rate, tumor size and anatomic site. The complete surgical resection and use of imatinib mesylate (Gleevec) are the best available approach.

Gastrointestinal stromal tumors are the most common mesenchymal tumors of the gastrointestinal tract. These tumors are present in almost all cases of KIT-CD117 mutations. When located outside the gastrointestinal tract, they are referred to as extra-gastrointestinal stromal tumors. We present a case of a 72-year-old female with acute abdomen. Computed tomography detected intestinal obstruction and failed to determine the causative pathology. The patient underwent urgent exploratory laparotomy, which revealed pelvic extra-gastrointestinal tumor originating from the broad ligament of the uterus. This case is unique with regard to symptoms and the unusual anatomic location of the mass. Surgeons should be aware of the extra-gastrointestinal stromal tumor entity and its manifestations and management.

Ovarian hemangioma is an uncommon ovarian tumor occurring in patients in different age groups. It is usually seen as small, asymptomatic mass, which is detected incidentally. On rare occasions, this type of tumor can be associated with other gynecological neoplasms. In this report, we present the clinicopathologic features of a case of ovarian hemangioma coexisting with multiple microscopic foci of dysgerminoma in a 10-year-old child. The patient presented with acute abdomen. Magnetic resonance imaging revealed a left ovarian mass and subsequent left salpingo-oophorectomy was performed. Grossly, the mass was 9.5 cm in diameter and contained hemorrhage and necrosis. Microscopic examination showed that the tumor was mostly composed of hemangioma. Additionally, there were three microscopic foci of dysgerminoma between the hemangioma and ovarian cortex. Immunohistochemical studies showed that dysgerminoma foci were positive for PLAP, Oct4 and CD117. To our knowledge, this is the first case of the above-described association ever reported.

Gastrointestinal autonomic nerve tumour (GANT) is a rare mesenchymal neoplasm of the gastrointestinal tract arising from the neural plexus of the intestinal wall. Herein, we present a 70-year-old male patient presenting with a clinical picture of acute abdomen. Examination of the specimen obtained from the small bowel by means of complete resection revealed a relatively soft submucosal mass measuring 4.5 x 3 cm in size with spindle morphology and high mitotic activity (> 10 mitoses per 50 high-power fields). The tumour cells were strong positive for c-kit (CD117), S-100 protein and glial fibrillary acidic protein (GFAP), but did not harbour mutations in the c-kit and PDGFR genes. The diagnosis was based on light microscopy and immunohistochemical verification. We started tyrosine kinase inhibitor 400 mg/day. The patient is currently alive without metastasis at 28 months postoperatively. He is under close follow-up and survival data of the patient will be presented in the later studies.
