[Colloid or mucinous adenocarcinoma of the prostate].

We report a mucinous or colloid adenocarcinoma of the prostate. Identification of this disease entity as such is strictly based on histological and immunohistochemical findings. Confusion as to the identification of this type of prostatic tumor results from its scant frequency (0.3%) and its being an exclusively morphological variant of the more common prostatic adenocarcinoma.
