[New immunohistochemistry markers to determine presence of vas deferens in vasectomy specimen.]

CONCLUSIONS: PAX8 is a useful antibody to confirm the presence of vas deferens in artifacted vasectomy specimens. CD34 and ERG are negative in the epithelium,and, otherwise, they are expressed by vascular endothelium, with the advantage of nuclear staining pattern for ERG. CD31, a classic endothelial marker, is not so specific as it had been stated as it shows weak or moderate expression in the vas deferens epithelium. PMID: 32633248 [PubMed - in process]
