Amputation neuroma following radical neck dissection--report of 3 cases.

Amputation neuroma occurred in three cases among 111 cases of oral cancer patients after radical neck dissection. All of three cases appeared as a small nodule at superior neck around the carotid artery with accompanying tenderness. The lesions were located in continuity with the proximal end of nerve at excision. Although the incidence of amputation neuroma is low, critical examination is required to distinguish this from recurrent tumor after cancer surgery.
