[Vasitis nodosa].

OBJECTIVE

To describe a case of vasitis nodosum causing spontaneous recanalization of the vas deferens.

METHODS

Herein we describe a patient who had undergone vasectomy 9 years earlier. A nodule in the vas deferens arising from granulomatous reaction had progressed to vasitis nodosum, causing spontaneous recanalization of the vas deferens.

RESULTS

Vasitis nodosum may be more frequent than it is considered to be although clinical problems rarely arise.

CONCLUSION

Confusion may arise in distinguishing the histological features of vasitis nodosum from those of adenocarcinomatous neoplasia. Although rarely, its growth may cause recanalization of the vas deferens in vasectomized patients.
