title: Isolated osseous ovarian metaplasia: case report.
abstract: 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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  A rarely occurring condition, ovarian osseous metaplasia continues to be of uncertain clinical significance.
