Leiomyomas of the uterine cervix: a study of frequency.

Leiomyomas of the cervix are said to be uncommon. To establish their frequency, 661 consecutive total hysterectomy specimens were examined macroscopically and microscopically. Myometrial leiomyomas were present in 427 uteri (64.6%) but cervical leiomyoma were present in only 4 (0.6%). One of these was 6 mm in diameter and occurred in a uterus without fibroids elsewhere. Only two could have been considered clinically significant. An additional six cases showed submucous fibroids of the body of the uterus protruding as a polyp into the endocervical canal but these were not considered cervical leiomyomas. The conclusion of the study is that cervical leiomyomas are extremely uncommon.
