Abstract

Background and Objectives Various distinct types of tumors can develop in the auricles;however, those have not been thoroughly studied clinically. The aim of the study is to assessthe clinical nature of auricular tumors. Subjects and Method We retrospectively reviewed medical records and pathological findingsin patients with auricular tumors who underwent surgical interventions at a single institutionfrom January 2011 to October 2023. Cases in which the location of the tumor could beidentified and pathological results were confirmed were included. We analyzed age, sex, tumorlocation and size, tumor occurrence period and causes, recurrence, and pathological results. Results A total of 98 auricular tumors were included in the study. Auricular tumors weremost commonly found on the lobule (32.3%), followed by the helix (30.1%) and the posteriorauricle (15.1%). The most prevalent pathological type of auricular tumors was an epidermalcyst (45.2%), followed by keloid (21.5%). A single case of squamous cell carcinoma was reported. Eight tumors recurred following surgical resection, with five cases of keloid, two casesof epidermal cyst, and one case of squamous cell carcinoma, with an average recurrence intervalof 6.1 months. Conclusion The present study assessed the largest number of auricular tumors collected ina single institution. Tumors with diverse clinical characteristics can develop in the auricle, andcosmetic considerations must be taken into account before undergoing surgical treatment. Thefindings of the present study could provide proper approaches to the auricular tumors.
