A rare case of schwannomatosis
نویسندگان
چکیده
Schwannomas are benign,slowly growing, encapsulated peripheral nerve tumors. Schwannomas are homogenous tumors and consist of only Schwann cells. They develop outside of the nerve, but may push it aside or against adjacent structure causing damage to the nerve. Most schwannomas occur as solitary lesions. Presence of multiple schwannomas in a single patient suggeststumorogenesis and a possible association with one of the syndromes such as neurofibromatosis 2 or with Schwannomatosis. Schwannomatosis is diagnosed in the presence of multiple pathologically proven schwannomas in the absence of neurofibromatosis2 (NF2). We report a very rare case of multiple schwannomasin the absence of typical signs and symptoms of NF1 and NF2. Key word: Multiple schwannomas, Schwannomatosis,Schwannoma, Neurofibromatosis
