[Multiple lipomatosis and Recklinghausen's neurofibromatosis (author's transl)].

On the occasion of two separate observations of multiple lipomatosis on a 48 years old female patient and a neurofibromatosis on a 49 years old male patient, the differential diagnosis of these diseases was compiled with regard to the cutaneous and subcutaneous symptoms and to the relations to the nervous system and the inner organs. The differential diagnostical plan requires a series of clinical examinations for the clarification of these pathological conditions, which often comprise more than one disease or one syndrome.
