[The so-called transitional-cell carcinoma of the prostate and its oncogenesis]

Report on two cases of so-called transitional cell carcinoma of the prostate. Clinically important differences to adenocarcinoma (above all ineffectivity of estrogen therapy and orchiectomy), histological differential diagnosis and therapeutic possibilities are reported on. Micromorphological similarities to the carcinoma of the cervix uteri allow for conclusions regarding histogenesis and oncogenesis, thereby possibly explaining marked differences of local growth and individual prognosis.
