A 53-year-old female with bladder leiomyoma: A rare case and review of the literature

Abstract

Leiomyoma as a benign tumor of the urinary bladder, is uncommon and usually presents with obstructive voiding symptoms or irritative urinary symptoms. A 53-year-old woman was hospitalized to the general surgery clinic due to abdominal pain. During her contrast-enhanced computed tomography (CT) examination, incidentally, a mass on the left anterosuperolateral side of the bladder wall was revealed. No significant finding was detected on physical examination. There was only microscopic hematuria as a result of urinalysis. Contrast-enhanced CT confirmed the presence of a mass on the left anterosuperolateral side of the bladder wall without evidence of extravesical extension and showed a well-delineated 2,6 cm x 2,4 cm endovesical bladder tumor arising from the left anterosuperolateral bladder wall and there was a thickening of the urinary bladder wall. On cystoscopy, an intraluminally protruding, rounded, smooth, sessile solid mass, 2,5 cm in diameter and covered by normal bladder mucosa, was seen. She underwent an uneventful transurethral resection of bladder tumor (TURBT) and histological examination revealed intersecting fascicles of smooth muscle without any evidence of malignant change, and thus diagnosis of leiomyoma was confirmed. Confirmation of the diagnosis may be difficult due to the poor yield of cold cup biopsy. In our case, transurethral resection (TUR) was diagnostic.
