Ovarian fibroma is one of the sex cord-stromal tumor, and accounts for about 5 percent of all ovarian tunors surgically removed. This tumor is almost always unilateral and appears to affect the left ovary more often (75%) than the right. Calcification is one of the secondary changes that can take place in a fibroma of ovary. The occurrence of ossification in these calcified fibromas is rare. We experienced a case of an ovarian calcified fibroma with ossification occurring in a 19 year old, unmarried woman with a brief review of literature.
