Intramural leiomyomas of the bladder in asymptomatic men

ABSTRACT

Bladder leiomyomas are rare benign mesenchymal tumors, which account for less than 0.43 percent of all bladder tumors with approximately 200 cases described in the literature. These tumors may be classified into 3 different locations endovesical, intramural and extravesical. Endovesical is the most common form, accounting for 63-86 percent of the cases, while intramural occurs in 3-7 percent and extravesical in 11-30 percent. The intramural form, especially small tumors, may not produce symptoms hardening detection. We report two cases of intramural bladder leiomyomas in asymptomatic men observed incidentally by transabdominal ultrasonography during the follow-up of benign prostatic hyperplasia. We discuss the diagnosis and management of these lesions.
