Malignant melanoma of the external ear.

Twelve patients with primary melanoma of the external ear were treated during a 10-year period. Ten patients were males. Median melanoma depth was 2.1 mm and seven patients had lesions deeper than 2 mm. Eight of 12 lesions were either Clark level IV or V. Six patients had wedge excisions of the primary lesion and all developed recurrent disease (local: three). Six patients underwent wide excision and none developed local recurrence. All patients with primary disease less than 2 mm are alive. Only two of seven patients with lesions deeper than 2 mm have survived. The definitive excision for melanoma of the ear should encompass wide margins despite the cosmetic consequences. Lesser procedures inevitably lead to local recurrence. Melanoma deeper than 2 mm penetration on the ear in our series had a poor prognosis.
