Melanosis of uterine cervix: a report of two cases.

Uterine prolapse is a common gynecological problem which is associated with complications like keratinisation, thickening and ulceration of cervical mucosal epithelium. Two cases of second degree uterine prolapse are being reported here showing heavy melanotic pigmentation of the basal layers of ectocervical epithelium. It appears to be a metaplastic change in response to local trauma or chronic irritation.
