[A contribution to the early diagnosis and differential diagnosis of bladder neoplasms by means of immunological methods].

According to the present examinations it is pretty probable that already in early histological forms of the carcinoma of the urinary bladder the EM-test is able to indicate immunologically malignity, i.e. that the papillary non-infiltrating carcinoma of the transitional cell as well as the carcinoma in situ of the urinary bladder (23) also immunologically behave like tumors of the bladder. In differential-diagnostic questions concerning the organ localisation of the primary tumor the EM-test seems to give valuable references. Histologically not unequivocally malignant tumors of the bladder with positive results in the EM-test should be submitted to an exacter examination and control.
