MALACOPLAKIA OF THE EPIDIDYMIS

A 65-year-old diabetic man presented with a painful swelling of his ri ght epididymis. Urine culture was sterile. Semicastration was performe d and histology revealed malacoplakia of the epididymis without involv ement of the testis. Histologic workup demonstrated typical von Hansem ann cells and Michaelis-Gutmann bodies stained by von Kossa's stain. T his is the 19th case of epididymal malacoplakia and the 9th case of ep ididymal malacoplakia without concurrent involvement of the testis. Li terature review shows that the present case is typical with respect to the clinical presentation and with regard to the age of presentation. The fact that this patient was suffering from diabetes mellitus lends some support to the assumption that a compromised immune status could be etiologic in malacoplakia.
