title: Trophoblastic differentiation in a malignant mixed mesodermal tumor of the ovary.
abstract: Trophoblastic differentiation in an extragonadal carcinoma is a rare and unusual phenomenon which has been observed in the carcinomas of stomach, bronchus, esophagus, ovary, liver, urinary bladder, endometrium, and, rarely, in the sarcomas. To our knowledge, this phenomenon has not been observed previously in a mixed mesodermal sarcoma (MMS), and the present communication is to record such a case of MMS of ovary with this phenomenon.
