[Blue naevus of the cervix. 3 case histories (author's transl)]

Anatomo-pathological features of 3 cases of blue naevi of the cervix are presented and discussed together with the literature. Blue naevi of the cervix are localised in the chorion of the endocervical mucus and sometimes even in a polyp, and can be multiple. They are different from benign melanosis or melanocytes which are found in the basal portion of the malpighian epithelium of the exocervix or the vagina. The blue naevus and benign melanosis can rarely give rise to primitive malignant melanomas of the cervix.
