The histological and molecular relevance of canine PC as a model for the disease in men remains controversial. To address this challenge, this study aimed to assess the histomorphology and expression of basal cell, urothelial and neuroendocrine markers [p63, high molecular weight cytokeratin (HMWCK), Uroplakin 3 (UPIII), neuron\u2010specific enolase (NSE)] in canine PC (\n                    <jats:italic>n<\/jats:italic>\n                    \u00a0=\u00a041). Based on histomorphology, 10\/41 (24%), 21\/41 (51%) and 9\/41 (22%) were classified as adenocarcinoma (AC), urothelial carcinoma (UC), and mixed carcinoma, respectively. Tumour inflammation was common, frequently severe [20\/41 (49%)], and associated with neutering (p\u2009&lt;\u2009.02) and urothelial differentiation (p\u2009&lt;\u2009.02). Most (36\/40, 90%) cancers contained only rare cells with basal cell marker expression or were negative. The expression of UPIII was absent or weak in the majority (33\/38, 87%) of tumours, with moderate to strong staining in the remaining cases. NSE expression in PC was rare and limited to 2\/14 (14%) cases. Tumour extension into benign ducts and glands was a common finding with presence in 17\/39 (44%) of carcinomas with and without urothelial differentiation. In conclusion, we confirm that canine PC is characterized by absent or weak expression of basal cell and urothelial markers. Although rare, NSE expression, potentially indicating neuroendocrine differentiation, is reported for the first time in canine PCa. Intraductal carcinoma of the prostate with concurrent invasive PCa (IDCP\u2010inv) is a frequent, not previously described, finding in dogs with PC.\n
