An extremely rare presentation of hybrid schwannoma/neuroma
Main Article Content
Abstract
Hybrid peripheral nerve sheath tumor(HPNST) is benign peripheral nerve sheath tumor which present as a soft tissue mass with or without neurologic symptoms. HPNST shows combination of more than one type of peripheral nerve sheath tumors such as schwannoma/perineurioma, neurofibroma/schawannoma and neurifibroma/ perineurioma. HPNST is rare disease that may be idiopathic or may occur in association with neurofibromatosis and schwannomatosis. HPNST have not been reported malignant transformation.
In this report, we present a case of HPNST that involve brachial plexus and never been reported in the previous literature.
