Giant Median Lobe Hyperplasia of the Prostate Mimicking Bladder Tumor: A Case Report

Abstract

Benign prostatic hyperplasia is a common cause of bladder outlet obstruction and may cause macroscopic hematuria. Giant median lobe hyperplasia is very rare and its definition is not clear. In this case report, the diagnosis and treatment of a case with giant median lobe hyperplasia of the prostate mimicking a bladder tumor were evaluated. A 65-year-old male patient was admitted to our clinic with a 9-month history of intermittent hematuria. Abdominopelvic computed tomography revealed a mass measuring 95x85x57 mm filling the bladder. A distinct anatomical plane between the mass and the seminal vesicles could not beidentified. In the urethrocystoscopy, it was determined that the mass was the giant median lobe of the prostate. Open suprapubic prostatectomy was performed. A total of 330 g prostate tissue consisting of 180 g median lobe was enucleated. Giant median lobe hyperplasia of the prostate is a rare pathology and may mimic a bladder tumor by causing painless hematuria.
