A case of ovarian fibrosarcoma with pregnancy / 대한산부인과학회지

ABSTRACT

Ovarian fibromas originating primarily from the ovarian stroma are rare, accounting for approximately 4% of all ovarian neoplasm. The ovarian fibromas are mostly benign tumors, but infrequently they have histologically malignant appearances such as hypercellularity, high mitotic rate, marked nuclear pleomorphism. Malignant fibromatous tumor can be categorized on the basis of prognosis into two separate types of tumors, one of which is cellular fibroma (one to three miotic counts per 10 high power fields) and the other of which is fibrosarcoma (over four miotic counts per 10 high power fields) that has extremely poor prognosis. We report a case of large ovarian fibrosarcoma accompanied with pregnancy and have a brief review of literatures.
