Dysgerminoma of the ovary with rhabdomyosarcoma. Report of a case.

A 14-year-old girl with a large left ovarian mass underwent excision of the tumor which on histologic examination revealed dysgerminoma mixed with elements of rhabdomyosarcoma. A subsequent staging laparotomy revealed a solitary 1-cm nodule along the pelvic wall. This was composed of rhabdomyosarcoma. Review of literature revealed that soft tissue sarcomas of several types may on occasion be seen in association with gonadal and extragonadal mixed germ cell tumors or in spermatocytic seminoma of the testis. However, no previously published report of a sarcoma arising in a pure dysgerminoma was found in the literature.
