The prostatic adenocarcinoma with mucinous features: A review of the literature with three case reports

Mucinous adenocarcinoma of the prostate is one of the rare variants of the prostatic carcinoma, and its incidence among all prostatic carcinomas is reported to be 0.3% in the literature. If the tumor variant containing extracellular mucin in <25% of the resected tumor mass, the histology is defined as adenocarcinoma with mucinous features. The mucinous adenocarcinoma of the prostate displays similar prognostic features with the classic adenocarcinoma. In this study, the treatment and surveillance processes of our three patients with prostatic adenocarcinoma with mucinous features were presented along with a literature review.
