Ovarian fibroma with metaplastic bone tissue: Case report

Fibromas are benign tumors of the ovary and arising from the stromal component of the ovary. Nearly half of the cases (40%) have tumor bigger than 10 cm in diameter. Only one third of the cases have smaller than 3 cm and they are rarely bilateral (5% of cases) In microscopic examination fibromas consist of cellular bundles and intersecting strips of hyaline-appearing collagen and fibrous tissue. Mitoses are rare, but occasionally fibromas may be hypercellular and/or show substantial mitotic activity. Dystrophic calcifications, focal necrosis and hemorrhage are common. In this report we described a case of unilateral fibroma of ovary that was found incidentally by laparoscopic surgery for chronic pelvic pain with pathologically consisting metaplastic bone tissue.
