Perineal leiomyoma mimicking complex Bartholin mass.

Leiomyomas of the external genitalia are uncommon soft tissue tumors. We report the case of a 47-year-old woman with perineal leiomyomas mimicking Bartholin's gland mass according to the preoperative magnetic resonance imaging (MRI) findings. Leiomyomas in the vulvar region should be differentiated from complicated Bartholin's gland cysts and preoperative MRI findings may be misleading. The complete surgical excision should be the choice of treatment.
