title: Ovarian dysgerminoma associated with fibrosarcoma: a case report.
abstract: A 35-year-old woman presented with abdominal pain and weight loss. Pelvic computed tomography showed a 15 cm mass in the left ovary. Grossly, the removed ovary was completely replaced by a solid tumor mass. On histological analysis (100 sections), the lesion showed the typical morphological features of dysgerminoma (20%) admixed with a major (80%) fibrosarcoma component. Tumors did not have well-demarcated boundaries with a close intermingling of both cell types. Despite surgery and combination chemotherapy, the disease progressed rapidly and the patient died of disease 18 months after diagnosis. Review of the literature showed that soft tissue sarcomas of several types may occasionally be associated with gonadal and extragonadal mixed germ-cell tumors or with spermatocytic seminoma of the testis. However, no previously published report of an ovarian fibrosarcoma associated with a pure dysgerminoma was found in the literature.
