An Incidental Finding of Endocervical Melanosis in a Polymyomatous Uterus.

Melanocytic lesions, whether benign or malignant, are extremely rare in the cervix and, more particularly, in the endocervical mucosa. Cervical melanosis is a benign entity, most often discovered by incidental findings on a histological study of a surgical specimen resected for another reason. The microscopic examination allows the diagnosis with certainty after ruling out any potential malignancies. The etiopathogenesis remains poorly understood; however, a number of theories have been put forward, such as excessive migration of pigmented cells from the neural crest, trauma, or chronic irritation situations. We report the case of a 40-year-old female patient followed in the gynecology department for a polymyomatous uterus. She underwent a total hysterectomy. The histological and immunohistochemical examinations concluded an incidental finding of cervical melanosis lesions associated with leiomyomas.
