Abstract
Schwannomatosis is a rare disorder, still not quite well defined, seldom described in the literature. In this paper we report the case of male. Patient, 52 years old, who in the last 30 years developed five subcutaneous tumors within his limbs peripheral nerves, which histologically proved to be schwannomas. A brain computed tomography showed a partially calcified tumor in the left temporal lobe which most likely was a meningioma. A thorough clinical examination was unable to find signs of type I or type II neurofibromatosis. The present condition, probably a form of phacomatosis, has to be distinguished from neurofibromatosis and is considered as an independent clinical entity whose origin still awaits further detailed investigations.
