Leiomyomatosis of the colon and mesentery: report of a case.

A case of leiomyomatosis of the colon and mesentery in a 35-yr-old man with several noninvalidating congenital malformations and multiple intracranial meningiomas is presented. The leiomyomatosis had been asymptomatic until 2 months before death, even though the lesions suggest a congenital disorder affecting the musculature of the bowel wall.
