title: Uterus-like mass in the uterine cervix: superficial cervical endometriosis with florid smooth muscle metaplasia?
abstract: This study describes a 47-year-old woman, gravida 2, para 2, with a uterine polypoid mass. The 25-mm mass, which was growing into the endocervical canal, had a central cavity lined with endometrium and surrounded by smooth muscle layers. It strongly resembled a miniature uterus. It is concluded that the mass represented superficial cervical endometriosis with florid smooth muscle metaplasia of endometrial stromal cells.
