title: Atypical leiomyoma of prostate.
abstract: A prostatic leiomyoma with nuclear atypia, similar in appearance to atypia sometimes seen in uterine leiomyomas, was an incidental finding in a fifty-three-year-old man who underwent prostatectomy for hyperplasia. The smooth muscle nature of the lesion was confirmed by electron microscopic examination. This is the third lesion of this type to be reported.
