Vascular plexiform leiomyoma mimicking uterine tumor resembling ovarian sex cord tumor.

Leiomyomata are common benign smooth muscle neoplasms with a usually easily recognizable histologic pattern. However, there is a wide variety of subtypes described in the literature, characterized by predominance of a particular distinct histologic pattern. Here we describe a case of a highly vascular leiomyoma with a prominent plexiform pattern and cords and tubules of epithelioid cells that mimics a uterine tumor resembling an ovarian sex cord tumor.
