Abstract

A schwannoma is a benign soft tissue tumor derived from Schwann cells of the nerve sheath. The lateral femoral cutaneous nerve is a sensory nerve originating from the second and third lumbar vertebra nerve roots, passing under the inguinal ligament and dividing into anterior and posterior branches. The anterior branch which is a major division and the main nerve that causes meralgia paresthetica supplies the knee joint from the anterior thigh. In addition, the posterior branch supplies the lateral thigh at the greater trochanter level. This paper reports the case of a 52-year-old woman with a very rare schwannoma in the terminal twig of posterior branch of the lateral femoral cutaneous nerve of right thigh protruded through the fascia lata with literatures review.
