前立腺膿瘍を契機に偶発的に発見された前立腺粘液腺癌の1例

概要

A 70-year-old man visited his doctor because of hip pain and gross hematuria. Digital rectal examination and computed tomography revealed a prostatic abscess. Although antibiotics were prescribed, his symptoms did not improve; he was transferred to our hospital, where transurethral fenestration of the prostatic abscess was performed. During prostatic fenestration, a papillary mucous membrane was confirmed inside the cavity of the prostatic abscess. Pathological examination revealed a mucinous adenocarcinoma of the prostate. Although hormonal therapy was administered, magnetic resonance imaging revealed tumor extension necessitating robot-assisted radical prostatectomy. Mucinous adenocarcinoma of the prostate is rare, and to our knowledge this is the first report of mucinous adenocarcinoma of the prostate diagnosed after transurethral treatment of a prostatic abscess.
