[Phaeochromocytomas in neurofibromatosis (author's transl)]

Neurofibromas and phaeochromocytomas derive ultimately from ectodermal tissue. It is therefore not surprising that there is an increase in the incidence of phaeochromocytomas in Recklinghausen's neurofibromatosis. When investigating hypertension in patients with neurofibromatosis one must therefore consider the possibility of a phaeochromocytoma as well as vascular involvement by neurofibromatosis. Two patients with neurofibromatosis and phaeochromocytomas are described.
