Abstract

The purpose of this retrospective study is to evaluate the frequency and further characterize the pathological features of common and uncommon histological lesions in 111 canine prostatic samples. Benign prostatic hyperplasia, suppurative and non-suppurative prostatitis, and prostate cancer were observed individually or in combination in 45, 11, 68 and 50 samples, respectively. Six growth patterns of prostatic carcinoma were differentiated: papillary, cribriform, solid, small acinar/ductal, signet ring, mucinous. In a few cases, perineurial invasion and collagenous micronodules were observed. Lesions considered preneoplastic in men, such as high-grade prostatic intraepithelial neoplasia (HGPIN) and prostatic inflammatory atrophy (PIA), were observed in 27 and 21 histological samples, respectively.

This study represents a detailed characterization of the different histological subtypes of canine prostate cancer. The awareness of the unusual patterns might be critical in avoiding diagnostic misinterpretation. The high prevalence of PIA and HGPIN underlines the reasonable chance of their detection in routine biopsy specimens.
