    Abstract:
    Two cases of vasitis nodosa are reported hereon. The two patients were 47 and 40 year old males with desire of refertility. They were performed vasectomy 23 and 10 years ago. They were subjected to vaso-vasostomy. During the operations, spindle shaped nodules were found in the vas deferens at the site of the previous vasectomy. Histologically, they showed focal proliferation of epithelial components forming glands, where a plentiful number of sperms were present, and this was also associated with proliferative change of smooth muscle bundles of vas deferens. Some foci of spermatic granulomas were also found. This condition was similar those of salpingitis isthmica nodosa in the fallopian tube. Vasitis nodosa should be differentiated from metastatic adenocarcinoma histologically. This condition may lead to re-canalization.
