Malignant schwannoma.

This paper reports a patient suffering from a malignant peripheral nerve sheath tumor, also known as a Schwannoma or neurilemoma. The patient demonstrated an increase in left thigh circumference, without apparent trauma. The report establishes the relationship of the lack of trauma and relatively mild symptomatology with malignant conditions, as well as the need for chiropractors to do thorough history, physical and radiological examinations. A brief review of pathophysiology and incidence is given.
