Melanoma of the external ear.

Management of melanoma of the external ear is controversial. Thirty-one patients treated for this disease were identified at our institution between January 1, 1974 and December 31, 1989. Follow-up was an average of 7.12 years (range 1-15). Local therapy performed included 16 wedge resections, 3 split thickness skin grafts after excision to the perichondrium, 10 partial and 2 total amputations. There were two local recurrences, four metachronous cervical metastases, and four distant metastases. Three elective and five therapeutic neck dissections were performed. Survivors at 1, 5, and 10 years were 93, 77, and 47%, respectively. There was no relationship between DNA ploidy, local surgical therapy, and eventual recurrence. Clinical stage and tumor thickness demonstrated a statistically significant correlation with likelihood of recurrence (P = .02 and .05). There is no evidence that melanoma of the ear has a poorer prognosis or different prognostic factors than melanoma at other cutaneous sites. In selected cases, local disease can be controlled by excision and skin graft rather than the more aggressive current procedures.
