Leiomyoma of the bladder

A case of leiomyoma of the bladder in a 37-year-old man is described. Clinical features and findings on excretory urography resembled a malignant tumor of the small pelvis. Ultrasound, computed tomography, and angiography nevertheless made the correct preoperative diagnosis. Special emphasis is given to the differentiation between benign and malignant smooth muscle neoplasms.
