We report the case of a 78-year-old male patient who presented with dysuria and lower urinary tract symptoms (LUTS). After routine blood and urine analysis, the patient underwent ultrasonography which revealed a hypertrophied and inhomogenous prostate extending to the bladder neck. Open biopsy from the bladder neck was performed. The histopathological findings were found to be consistent with prostatic duct adenocarcinoma with endometrioid features.Key Words: Prostate, duct, carcinoma, endometrioid, lower urinary tract symptoms (LUTS), dysuria
