Prostate Basal Cell Carcinoma: A Case Report

Abstract

Prostate basal cell carcinoma (PBCC) accounts for 0.01% of all prostate cancers. A 68-year-old man complained of dysuria for 5 years on his initial visit. His PSA level was 3.87 ng/mL. Due to a diagnosis of benign prostate hyperplasia, he underwent transurethral resection of the prostate. A pathological examination revealed that basal cell-like atypical cells made alveolar with palisadal layout. Immunohistochemical analysis showed positive 34β12, P63, and Ki-67. Based on these findings, PBCC was diagnosed. Then, we performed radical prostatectomy. He was free from recurrence 22 months after the operation. We herein report an extremely rare case of PBCC.
