Ectopic prostate tissue is a rare occurrence in the lower female genital tract. Possible theories of histogenesis include a developmental anomaly, metaplasia of preexisting endocervical glands, and derivation from mesonephric remnants. We report an example of prostatic tissue involving the uterine cervix of an 82-year-old woman as an incidental finding in a hysterectomy specimen. This unusual lesion should be differentiated from atypical glandular lesions of the cervix. Immunohistochemical studies confirm the histological suspicion of ectopic prostatic tissue.
