Malignant schwannoma of the planta.

Schwannomas (neurilemmomas) are common tumors originating in the sheaths of peripheral nerves. The tumor may have the appearance of a reddish-brown or pale papule that is painful or itching. The surface is usually smooth but may be ulcerated or verrucous. Malignant reversal is rare. The authors present the case of a twenty-year-old patient with a malignant schwannoma of the plantar portion of the heel. They describe the surgical approach, the results of histopathological examination and subsequent follow-up.
