Incidental detection of pigmented lesions in the cervix.

The occurrence of non-neoplastic melanin-laden cells in the uterine cervix is a rare phenomenon and pigmented lesions of the cervix account for very few cases in the literature. Lesions varying from incidental melanosis and benign blue nevi of the cervix to malignant melanoma have been described. Possible histogenesis as well as the course of these lesions is debatable. Neural origin is the most acceptable hypothesis for the origin of these lesions. Herein two cases of pigmented lesions of the cervix one in ectocervix and the other in the endocervical stroma are reported. (excerpt)
