- Abstract
Eight cases of adenomatoid tumors of the male genital tract are presented. Histological, histochemical, and electron microscopic studies were performed and an approach to a new classification of adenomatoid tumors was discussed. The number of so-called adenomatoid tumors of male genital tract reported in Japan adding our eight cases totalled 60 cases. These were classified as follows; 10 cases of mesothelial (superficial) type and 50 cases of adenomatoid (profound) type. Besides these, 8 cases of mesothelial type were reported in foreign literatures. Three cases of adenomatoid tumors of the uterus and a case of epididymitis chronica with reactive proliferation of mesothelial cells were also examined. As a result of these investigations, it is suggested that the histogenesis of the so-called adenomatoid tumors is composed of two different processes; i.e., mesothelial type arising from serosal mesothelial cells. and adenomatoid type arising from immature Müllerian mesenchymal tissue.
