Primary malignant melanoma of the uterine cervix is a rare neoplasm with poor prognosis. It may be misdiagnosed especially when amelanotic, in which case immunohistochemistry is useful in reaching the diagnosis. We present one such case of a 65-year-old postmenopausal female patient presenting with bleeding per vaginum. Speculum examination revealed an ulcero-proliferative growth involving the cervix. On histopathological examination it was originally suspected to be a poorly differentiated carcinoma or a non-epithelial malignant tumor, but was subsequently correctly diagnosed by immunohistochemical staining with the HMB-45 antibody and S-100 protein.

Mullerian adenosarcoma is a rare biphasic malignant neoplasm of the cervix characterized by an admixture of benign epithelial elements and a malignant sarcomatous stromal component, which may be either homologous or heterologous. An aggressive variant of adenosarcoma, mullerian adenosarcoma with sarcomatous overgrowth (MASO) is extremely rare, with only two such cases being reported in the English literature to date. In this report we present a case of MASO of uterine cervix with heterologous elements in a 15-year-old unmarried girl presenting with foul smelling menstrual bleeding and passage of fleshy masses. Because MASO with heterologous elements seems to appear at the earliest stages of reproductive lifespan in women, and have an uncertain malignant potential, gynecologists and pathologists should be aware and think about the possibility of this tumor.
