Giant multilocular prostatic cysts treated by laparoscopic prostatectomy: a rare case report in China mainland

Middle-aged men presenting with symptoms of voiding dysfunction are often misdiagnosed with benign prostatic hyperplasia, urethral stenosis or neurogenic bladder. Here, we report a rare case of a 46-year-old man with a chief complaint of continually voiding dysfunction, diagnosed with giant multilocular prostatic cysts. Computed tomography (CT) scans showed multiple and large multilocular prostatic cysts in the pelvis. Serum levels of total and free prostate specific antigen were normal. Histological evidence of prostatic inflammation is presented in biopsy, including active hyperplasia and mild atypical hyperplasia of the prostate epithelial cells. Also, there were abundant neutrophil infiltrations in prostatic cyst fluid, however, without malignant cells. 25 days later, multilocular prostatic cysts were relapsed and Laparoscopic prostatectomy was performed. Histopathological examination indicated large multilocular retention cysts of prostate and intracystic hemorrhage. At 3 months follow-up, the patient was recovery and no prostate cyst recurred.
