Tumors of the peripheral nervous system are classified according to the specific origin of cell differentiation. Schwannomas (neurilemmomas) are benign nerve sheath tumors slowly growing, often solitary, arising from the nerves' Schwann cells that are not generally associated with malignant degeneration. The cause is unknown. The authors present a case of a 37-year-old woman with a lump formation located at the anterior aspect of the knee joint, inducing a burning-like sensation around the knee and up the whole hip. The pain increased through motion of the knee joint and during palpation. Prior to these complaints, the patient does not recall any trauma or degenerative knee conditions.

Keywords: peripheral nerve system tumors, Schwann cells, hypersensitivity, paresthesia neoplasm, neurilemmoma,
