Intravesical Ectopic Prostatic Tissue May be Misdiagnosed as Nephrogenic Adenoma: a Case Report and Overview

Abstract

Background Ectopic prostatic tissue is a relatively infrequent condition, usually found accidentally during imaging examinations or surgery. From 1967 to 2021, the reports of ectopic prostate tissue in English literature are increasing. It is rarely reported that ectopic prostate may be misdiagnosed as a nephrogenic adenoma (NA). Case presentationThis article reports a 45-year-old male patient with no symptoms. The computed tomography (CT) scan revealed a homogeneous isoechoic mass in the posterior inferior wall of the bladder. Firstly, the transurethral cystoscopic biopsy revealed a smooth sessile mass that covered normal bladder mucosa located in the middle of the interureteric ridge, and pathological results considered an intravesical NA. Then, the mass was completely resected under laparoscopic pneumovesicum and the pathological diagnosis was ectopic prostate tissue. Conclusions The clinical symptoms of ectopic prostate were similar to other bladder neoplasms, and fewer characteristics of imaging examinations are available to diagnose. Surgery was the mainstay treatment of ectopic prostatic tissue and has a good prognosis. Ectopic prostatic tissue presents as a tumor in the bladder, urologists may easily misdiagnose the condition like a tumor. Therefore, it is necessary to awareness of ectopic prostatic tissue to avoid misdiagnosis.
