[Leiomyoma of the ovary. Apropos of 12 cases]

Twelve ovarian leiomyomas were seen over a 12-year period, representing one quarter of all reported cases. Most of them were situated in the ovarian hilum (9/12 of our cases), some were situated in the medulla (2 of our cases) and one case was situated in the cortex. They were fairly small and, due to their site, they were generally asymptomatic and rarely diagnosed on ultrasonography.
