Leiomyoma of scrotum

Pedunculated scrotal mass: leiomyoma of scrotum

Scrotal leiomyomas of the tunica dartos are extremely rare and usually misdiagnosed. A case of a pedunculated mass observed expectantly over thirty years demonstrates the benign oncologic natural history of this lesion despite its capability for substantial growth. Only limited local surgical management of such lesions is indicated.

Retrovesical leiomyoma

Primary tumors arising in the retrovesical area are rare. We recently treated by primary excision a large retrovesical leiomyoma in a forty-five-year-old man. The smooth muscle nature of the tumor was confirmed by electron microscopy. Recognizing this entity is important, since treatment consists only of surgical removal, and the prognosis should be excellent.

Genitourinary leiomyomas

Leiomyomas may originate from any anatomic location of smooth muscle in the genitourinary system but are uncommon neoplasms. Five unusual cases of leiomyomas arising from the renal pelvis, bladder, spermatic cord, and glans penis are presented. The leiomyoma arising from the glans penis in a three-year-old boy is the first case of a leiomyoma in that location noted in the literature. A review of leiomyomas from each genitourinary structure of origin is presented.
