A Case Report on Malignant Peripheral Nerve Sheath Tumor in Fascia with no Connection with Great Peripheral Nerves

peripheral nerve sheath tumor is a rare soft tissue tumor which originates from peripheral nerves and neurofibromatosis. This tumor has two types of low and high grade. There is a poor level of prognosis in high grade tumors. MPNST may show a variety of histology; therefore, the diagnosis of MPNST is often confused with other soft tissue tumors. The low grade has good prognosis, but the nature of these tumors has never been systematically assessed. In this article we present a low grade malignant peripheral nerve sheat tumor in a 20-year old man who presented himself with occasional pain in the antero medial surface of his right thigh (10 cm. above the knee) for several months. Neuroma was clinically suspected. He undertook a surgical operation and the complete resection of tumor resulted in a complete resolution of the symptoms.
