Osseous metaplasia of the cervix: A rare transformation.

Although numerous cases of endometrial osseous metaplasia appear in the literature, only 6 cases of osseous metaplasia of the cervix have been reported since 1982. A 30 years old nulligravida women was referred to our colposcopy clinic with cervical mass. General, gynecologic and colposcopic assessments were done. The patient had an excision biopsy. Diagnosis of cervical osseous metaplasia was confirmed on histologic examination. The cervical epithelium has the potency to differentiate to multiple types of epithelium including osseous epithelium.
