Bladder leiomyoma: report of two cases and literature review.

Address correspondence to Dr. Saleh A. Binsaleh, Division of Urology, McGill University, 1212 Pine Avenue West, Montreal, Quebec H3G 1A9 Canada abdominal ultrasonography appearing as a continuation of the central portion of the prostate. The patient reported a history of hesitancy, dribbling, and weak urinary stream. There was no history of gross hematuria, weight loss, or other urological or constitutional symptoms. Physical examination was completely normal, including a normal rectal examination. All laboratory investigations were normal including a normal urinalysis, urine cytology, and a PSA of 0.43 ng/ml. A cystourethroscopy revealed a large solid bladder tumor extending from the bladder neck to the right postero-lateral wall causing an intermittent bladder outlet obstruction. A biopsy of this mass showed chronic inflammation with Von Brunn’s nests and no evidence of malignancy. A transrectal ultrasound revealed a bladder mass distinct and separate from the prostate. An abdominal and pelvic CT scan confirmed this enhancing bladder mass (6.5 cm X 5.5 cm) with normal upper urinary tracts. This patient underwent a transurethral resection of this mass (TURBT), with only a small portion resected. The final pathology for it was a benign bladder leiomyoma. Subsequently, a two-staged TURBT was performed with over 140 grams of tissues resected. During resection, care was taken to preserve the bladder neck. Post-operatively, during the short-term follow-up, the patient did well with no reported complications. A repeat abdominal Bladder leiomyoma: report of two cases and literature review
