[Nephrogenic bladder adenoma associated with glandular cystitis. Immunohistochemical study and significance].
A histopathological and immunohistochemical study of a case of nephrogenic adenoma of the bladder associated to glandular cystitis is presented with a very similar immunostaining to adenomatoid tumors in other organs and probably of a mesothelial origin. Its pathogenesis seems to correspond to a metaplastic change of the bladder's urothelium through anomalous differentiation of the reserve cells faced with different irritating agents. Because of its benign characteristics, we think that treatment can be confined to endoscopic observation and conservative technique.
