We describe a case of osseous metaplasia into the cervical canal in a 41-year-old woman. The patient had a history of primary infertility, pelvic pain, chronic endocervicitis, and bone formation in the upper third of the cervical canal. After antibiotic therapy, we removed bone fragments by operative hysteroscopy using grasping forceps. The fragments were completely removed with no evidence of recurrence at 1-year follow-up. Chronic endocervicitis may cause endocervical ossification and should be ruled out before surgical removal of bone fragments in order to ensure definitive resolution and prevent recurrence.
