    AbstractTwo cases of vasitis nodosa, one typical example and one unusual case, are presented. The first case was a complication of a previous vasectomy, manifested as a painful nodule at the site of previous surgery, and was associated with sperm granulomas. In the second case, no antecedent vasectomy had been performed, the lesion was located deep in the scrotum, and inflammation was scant. The clinical diagnosis of adenomatoid tumor was also consistent with some aspects of the histopathologic picture. In such cases, the diagnosis of vasitis nodosa can be resolved by finding spermatozoa within the proliferating ductules and individual epithelial cells. Electron microscopy can also be useful in eliminating the possibility that the nature of the proliferating cells is mesothelial. However, the etiology of vasitis nodosa in the absence of previous local traumatic or inflammatory insults remains obscure.
