Abstract

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

Abstract

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasm of gastrointestinal tract that originate from Interstitial Cell of Cajal (ICC). The correct diagnosis of GISTs is important for therapeutic reasons of imatinib. Recently, DOG-1 has been introduced as an important diagnostic marker with high sensitivity and specificity. We report a caseof 40 years old woman with pain and swollen stomach in left lower quadrant since four month before come to the hospital. Ultrasound examination showed hipoechoic lession in the posterior of uterus and ascites. Paraovarian mass attached to the transverse colon and ascites was found on surgery. Histopathology diagnosis was a mesenchymal stromal tumour suggestive malignant GIST. Citological examination of asites fluid show a malignancy metastases. Immunohistochemistry showed negative for c-kit and positive for DOG-1, the conclusion is a GIST. Immunohistochemistry examinations are important to make defenitive diagnosis for GIST.  C-kit-negative GIST sare still rare, but defenitive diagnosis must be made because related to target therapy. DOG 1 has been proven in 89% of c-kit-negative GIST and claimed more sensitive and spesific.Keywords: GIST, c-kit, DOG-1, ICC, paraovary

Abstract

Background: Gastrointestinal stromal tumors (GISTs) are the most frequently seen mesenchymal neoplasm in the digestive system. GISTs was originally described as smooth muscle tumor in the 1980s but advances in molecular diagnostic methods and immunohistochemistry moved GISTs into a different category from smooth muscle tumors. The study aims to report on epidemiological, clinical, immunochemical, and therapeutic characteristics of GISTs. Methods: We performed a retrospective descriptive study of 28 cases of GIST in the gastroenterology and general surgery departments of M. Djamil General Hospital Padang, Indonesia was conducted from January 2019 to December 2021. Data collection using medical records of patients in M. Djamil General Hospital Padang, Indonesia. We reported different data: Age, sex, symptoms, site, and immunohistochemistry of the tumor.  Results: Our study included 28 patients 18 males (64,3%) and 10 females (35.7%), with a median age range of 51-60 years. The presenting symptoms were abdominal mass (53.6%), abdominal pain (14.3%), bloody or dark-colored stools (14.3%), constipation (7.1%), fatigue (7.1%), and nausea and vomiting in 1 case (3.6%). Sixteen patients (57.1%) had a primary tumor and twelve patients (42.9%) had further metastatic lesions. The tumors were found in the stomach (21.4%), small intestine (14.3%), rectum (14.3%), and in other sites such as the retroperitoneal, liver, and distal pancreas. The immunohistochemical study was performed in seven cases (expression of  CD117 and DOG1), in four cases  CD117 was positive, while in three cases CD117 was negative. In two cases, the expression of DOG1 was positive, while in one case, it was negative. Eighteen patients with GIST (64.3%) underwent surgical procedures. A combination of surgical and chemotherapy was prescribed in 9 patients (32.1%). The chemotherapy regimen prescribed is imatinib. One patient is inoperable and has received symptomatic treatment. Conclusion : In conclusion, our result showed that GISTs are highest in the male population with an age range of 51-60 years. The most common symptom of GISTs is abdominal mass. Patients who have been diagnosed with GIST by histopathological examination do not always show positive expression in the immunohistochemical study. Surgical resection was indicated in the majority of patients, and a combination of surgery and chemotherapy is also prescribed as a treatment for patients with GIST.
