Malignant Peripheral Nerve Sheath Tumor of Thigh Region - A Case Report

Malignant peripheral nerve sheath tumor (MPNST) is derived from Schwann cells or pluripotent cells of the neural crest. MPNSTs (Malignant Peripheral Nerve Sheath Tumor) commonly arise in adult patients ranging from 20 to 50 years of age. They originate from a major or minor peripheral nerve branch or its sheath. The common sites of origin include the extremities and trunk. We reported a case of MPNST in 35 years old female patient with rapidly growing mass in her left thigh. Histopathological examination and immunohistochemistry confirmed the diagnosis of MPNST. This case report of Malignant peripheral nerve sheath tumor (MPNST) is presented because of its rarity.
