Sarcomas in ovarian mucinous tumors: a report of two cases.

Two sarcomas that appeared as distinct solitary nodules in the walls of ovarian mucinous cystic tumors are described. One of the tumors was a fibrosarcoma associated with a mucinous cystadenoma; the other was an undifferentiated sarcoma in a mucinous cystadenocarcinoma. Both patients died within 1 1/2 years of their operations with distant metastasis; one of them had had metastatic sarcoma in the para-aortic lymph nodes at the time of exploration. These two cases are the only well-documented examples of this unusual combination of tumor types.
