title: Malacoplakia of testis.
abstract: A case of malacoplakia of testis with a typical clinical course, related to urogenital E. coli infection is presented. By means of electron microscopy, we have identified several forms of Michaelis-Gutmann bodies within the lesion. X-ray spectral analysis revealed that these bodies contain large amounts of calcium, phosphate, sulfur, sodium and chloride. The pathogenesis of malacoplakia and the formation of Michaelis-Gutmann bodies is shortly discussed.
