Primary malignant melanoma arising from the ovarian mature cystic teratoma is extremely rare, with only 31 cases have been described in the literature. It is one of the rarest forms of malignant transformation of ovarian mature cystic teratoma and usually develops unilaterally after menopause.

The diagnosis was confirmed by positive immunohistochemical results of S-100 protein and HMB 45. Here we report the rare case with review of literature.
