“…Prior to the general use of MMS, invasive SCC of the ear was a severe disease with a high recurrence rate, metastasis, and morbidity. Until 1983, the reported recurrence rate of SCC treated with conventional simple excision was 14 to 16.6% 1,3,4,13 . In the treatment of invasive SCC, MMS provides the maximum tissue conservation and statistically superior cure rates 14–16 .…”

Background. Squamous cell carcinoma (SCC) of the ear compared with SCC occurring at other skin sites has an increased incidence of recurrence following treatment. Objective. To determine the following variables: patient age and gender, life status, tumor location, and recurrence rate following Mohs micrographic surgery (MMS). Methods. The charts of 117 patients with 144 invasive SCCs of the auricle were reviewed. The patients were contacted by telephone to confirm tumor recurrence and patients' life status. The range of follow‐up was 7 to 67 months (average 34.6 months) after MMS. Results. The patients' ages ranged from 34 to 90 years (mean age 71 years). The male to female ratio was 22:1. The helix was the most common site of occurrence (50.7%). Local recurrence after MMS was found in four patients (five tumors). MMS was performed on these five recurrent tumors, with no further recurrences. Telephone confirmation was obtained on 91 patients (26 patients could not be contacted) with 122 tumors, which included the 4 patients with 5 recurrent tumors. There were no additional recurrences. Of these 122 tumors, 35 were followed for less than 2 years (average 16.6 months), and 87 were followed for 2 years or more (average 41.8 months). From the chart review and telephone contact, the 2‐year local recurrence rate was 5.7% (5 of 87 tumors) after MMS. The average size of these 87 tumors was 3.5 cm2. Twelve of 91 patients had died with evidence of active disease from causes unrelated to SCC. Conclusion. Invasive SCC of the ear was once a formidable disease with a severe prognosis. The course of this disease has been appreciably improved by early diagnosis and treatment with MMS. SIRUNYA SILAPUNT, MD, S. RAY PETERSON, MD, AND LEONARD H.

“…Cutaneous neoplasms of the ear often behave in an aggressive manner. Fredrichs, 11 Blake and Wilson, 12 and Pless 13 reported a 16% tumor recurrence rate in studies of ear tumors treated with standard surgical excision. When less aggressive tumor margins were used or when radiation therapy was applied as primary treatment, local tumor recurrence rates of 25%‐50% were found.…”

Thirty-four patients with tumors in the conchal bowl were treated with Mohs micrographic surgery. Twenty-six patients had basal cell carcinoma and 8 patients had squamous cell carcinoma. Thirty-three of 34 patients achieved a tumor-free margin during initial therapy. All patients remain free of recurrence and metastasis at an average follow-up period of 2.9 years. Thirty-three of 34 patients were allowed to heal by second intention. Only one patient required reconstruction to avoid stenosis of the external auditory canal.

“…M alignancies on the external ear , that is, the pinna, external auditory meatus, tragus, and immediate periauricular structures, constitute about 7% of all cutaneous cancers, averaging reported series whose figures range from 4.6% to 9.7%,. Basal‐cell and squamous‐cell carcinomata are the most common malignant neoplasms that develop on the external ear; other types of malignancy are uncommon there ,. A review of several series with a total of 780 patients shows that 55% had squamous‐cell carcinomas; 40%, basal‐cell carcinomas; and 5%, other types of malignancy (see Table ).…”
