RESUMO
Granulosa cell tumors are relatively low-grade malignancies accounting for about 1 to 2% of all primary ovarian neoplasms and have an indolent growth pattern. There are two types of tumors, adult type granulosa cell tumor (AGCT) and juvenile type granulosa cell tumor (JGCT), and each tumor reveals different clinical or histopathological features. The clinical manifestations are mostly associated with estrogen produced by tumor, which are vaginal bleeding or menstrual irregularity in AGCT and precocious puberty in JGCT. Although most patients are diagnosed in early stage with favorable prognosis, some recur after several years. So, continuous follow up is required. Recently, we experienced two cases of adult type granulosa cell tumor and report with a brief review of literatures.

About 15 to 20% of ovarian tumors are of germ cell origin, and about 95% of these are cystic teratoma. when the teratoma is composed either entirely or predominantly of thyroid tissue, it called struma ovarii. Struma ovarii represents about 2.7% of cystic teratoma. The incidence of malignant struma ovarii is probably much less than 5% of all struma ovarii. We have observed a case of malignant struma ovarii originated from the left ovary of a 46-year-old woman, and present this case with a brief review of concerned literatures.
