Isolated osseous ovarian metaplasia: case report.

BACKGROUND: Some ovarian metaplasias may contain bone or osteoid tissue. The most common tumors presenting these alterations are teratomas and mixed mesodermal tumors with heterologous elements. CASE REPORT: We report the case of a woman who, during gynecologic follow-up for chronic anovulation at the age of 31 years, presented a solid ovarian ultrasonographic image with calcifications. After laparoscopy and histological examination it was found to be an isolated ovarian osseous metaplasia. CONCLUSION: A rarely occurring condition, ovarian osseous metaplasia continues to be of uncertain clinical significance.
