BACKGROUND AND OBJECTIVE: @entity957 of the pinna seems to be associated with a worse prognosis as compared to other locations. @entity1 /METHODS: We studied 88 @entity1 treated between 1975 and 1990 for a @entity957 of the pinna. RESULTS: Lymph node @entity3 were present in eight cases (9%) prior to treatment. Treatment was intended to be curative in 83 @entity1 (94%). Tumor therapy was operative in all cases. Radiotherapy was instituted postoperatively in three @entity1 ; five @entity1 (5.7%) died due to the @entity5 . Of 83 curatively treated @entity1 , only 2 died of @entity5 progression. The survival rate was 98% after 2 years and 95% after 5 years. The recurrence rate was 7% after 1 year, 13% after 2 years, and 18% after 5 years. The outcome with @entity5 control and survival was significantly poorer when neck @entity3 were present. CONCLUSIONS: We recommend @entity5 excision with wide margins (5-10 mm) as first-line treatment. Neck dissection with parotidectomy is indicated when suspicious lymph nodes are detected by ultrasound sonography, the @entity5 diameter is > 4 cm, @entity3 is present, and vertical @entity5 thickness is > 5 mm.
