Skin Cancers of the Auricle: A Retrospective Analysis of 41 Patients.

OBJECTIVE: Skin cancers of the auricle usually present with challenges because of the unique anatomy and topography of the auricle and the behavior of the tumor. The purpose of this study was to evaluate the clinical and histopathological characteristics and the surgical outcomes in patients with skin cancer of the auricle.
METHODS: Medical records of patients who underwent surgery for a skin cancer of the auricle at two different tertiary medical centers during 2010 to 2020 were reviewed retrospectively. Sociodemographic data of patients, tumor location and size, histopathological type and subtype, T-stage, recurrence, and reconstructive technique were evaluated.
RESULTS: The study included 41 patients with skin cancers of the auricle. Thirty-six (87.8%) were male and five (12.2%) were female; with a male-to-female ratio of 7.2:1. The mean age of the patients was 71.4 (46-92) years. Eighteen (43.9%) tumors were basal cell carcinoma (BCC) and 17 (41.5%) tumors were cutaneous squamous cell carcinoma (cSCC). The most common subunit for tumor location was the helix (n=17, 41.5%). Wedge resection plus primary closure was the most common surgical technique (58.5%). Recurrent disease was detected in five patients (12.1%).
CONCLUSION: The frequency of the skin cancers of the auricle was remarkably high in men, and the helix was the most common subunit. Both BCC and cSCC were the most common histopathological types. Poor prognostic factors such as lymph node metastasis, perineural invasion, and recurrence were relatively common in patients with cSCC of the auricle. © Copyright 2020 by Official Journal of the Turkish Society of Otorhinolaryngology and Head and Neck Surgery.
