Leiomyoma of the urinary bladder.
Benign mesenchymal tumors of the bladder are rare and comprise less than 1% of the all bladder neoplasms. Leiomyoma is the most common type and comprises 35% of these tumors. These tumors may develop in submucosal (63%), intramural (7%) or subserosal (30%) layer, at any region of the bladder. The clinical presentation is varied and may include obstructive symptoms(50%), irritative symptoms (38%) and hematuria (11%). There are asymptomatic cases (19%), which make the diagnosis more difficult. Occurs more frequently in women than in men (3:1). The most common diagnostic investigations are ultrasonography, intravenous urography, computerized tomography scan and the magnetic resonance imaging. A 66 year old man presented with long standing voiding obstructive symptoms. Various examinations were performed in the last 2 years and was diagnosed either prostatic enlargement or bladder tumor. Cystoscopy was not available for confirming the diagnosis. The surgical exploration revealed a well-circumscribed mass at the bladder neck with moderate enlargement of the prostate. The pathological examination revealed a leiomyoma of the bladder. The post operative period was uneventful and the patient is doing well, without recurrence of the symptoms.
