Vasitis nodosa and spermatic granuloma of the skin: an histologic study of a rare complication of vasectomy.
A 29-year-old man noticed localized painful swelling of the scrotal skin after elective vasectomy. The lesion was excised and its histologic examination revealed a diffuse inflammatory, partly granulomatous infiltrate with numerous tubular structures in the dermis and subcutaneous tissues. ⋯ The inflammatory infiltrate consisted of lymphocytes, plasma cells and histiocytes, but also contained spermatozoa and a few spermatic granulomas. These changes were the sequelae of a vasocutaneous adhesion and fistula; the ductules were the result of epithelial regeneration from the vas deferens and the inflammation with spermatic granulomas was due to extravasated spermatozoa.
