[Primary bladder carcinoma on diverticulum. Clinico-pathologic study of 5 cases].
This paper reviews our experience with the vesical cancer which develops on the diverticulum, a situation occurring in 1.5% of all vesical tumours in our setting. The condition's clinical features (diagnostic and therapeutic), usually detected in advanced stages, are emphasized. From a morphological point of view, histology of over half these tumours differs from the pure transitional one. There were two cases of pure transitional carcinoma, one small cells cancer, one squamous cells cancer and one with adenocarcinoma differentiating foci. Several sets of data, which include histological variability as well as presence of congenital diverticulum and urethral tumours, have led us to suspect the existence of morpho-genetical factors in the development of these neoplasias. However, the widely accepted carcinogenetic theory continues to be the most likely.
