Malacoplakia: a case involving epididymis and a case involving a bladder complicated by calculi.

We report the sixth case of malacoplakia of the epididymis in the world literature and the first to occur in a patient who had undergone a vasectomy previously. The patient was treated successfully by epididymectomy. Another case of malacoplakia of the bladder is reported in which multiple adherent stones developed on the surface of the lesion. Long-term antibiotic therapy led to stabilization of bilateral obstruction at the ureterovesical junction.
