Analysis of Germ Cell Tumors of Ovary in a Tertiary Care Hospital: A Two Year Retrospective Study

Background: Germ cell tumors of the ovary are a rare and complex group of heterogeneous neoplasm that comprises both benign and malignant histologies. A mixture of histologic subtypes may be present within any single germ cell tumor. Aim: Aim of this study was to evaluate germ cell tumors in our institution. Materials and Methods: All cases of ovarian tumors during the period from May 2013 to June 2015 were retrieved from the record files of the Department and germ cell tumors were selected for analysis. Results: A total of 110 patients were included with a mean age of 28 years. Teratomas were most frequently found (mature: 98 cases, immature: 01 case), followed by dysgerminoma (05 cases), yolk sac tumor (02 cases), embryonal carcinoma (01 case), squamous carcinoma arising in mature teratoma (01 case), and mixed germ cell tumor (01 case). Abdominal mass (58 cases) and abdominal pain (35 cases) were most common presenting symptoms. Conclusion: Mature teratoma is the most common germ cell tumor, most commonly occurring in the 3rd decade. Dysgerminoma is the most common malignant germ cell tumor occurring in the 11-20 years age group.
