Vasitis nodosa is a complication experienced in approximately 66% of men who undergo vasectomy.[1] It is a benign nodular thickening of the vas deferens, in which small offshoots proliferate, infiltrating surrounding tissue.[2] It can be mistaken for low-grade adenocarcinoma by pathologists,[3] and is implicated in late vasectomy failure.[2]
