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

Introduction : Germ cell tumors arise from primordial germ cells and account for about 30% of all ovarian tumors. More than 95% of this group are benign dermoid cysts (mature cystic teratoma) and the remaining 5% are malignant. Ovarian teratomas represent 15% to 20% of ovarian germ cell tumors. Teratomas are classified as mature or immature and often consist of several embryological layers. While the mature type is benign, the immature type is more aggressive.Objective : Based on the above, this article will review about immature teratoma and mature cystic teratoma of the ovary. Material and methods : The method of writing this scientific paper is a literature review. The data used are sourced from relevant literature and in accordance with the topics discussed.Result : Teratomas are a common form of germ cell tumors. Teratomas are histologically defined as tumors containing tissue derived from all germ cell layers: ectoderm, mesoderm, and endoderm. Teratomas are classified as immature teratoma, mature teratoma and monodermal teratoma.Conclusion : Teratomas are usually asymptomatic and if there are symptoms, they tend to be non-specific. In patients with no residual tumor after surgery, the survival rate is 90-100%.Keywords: Teratoma, Immature Teratoma, Mature Cystic Teratoma
