A Case of Auricular Schwannoma After Trauma / 대한이비인후과학회지

ABSTRACT

Schwannoma is a slowly-growing, benign tumor that originates from the Schwann cell and is rarely found in the auricle. In this article, we describe a 20-year-old male patient with an approximately 2 cm auricular mass located in the antitragus of the left ear. The mass was slowlygrowing following an auricular trauma. The mass was completely removed by local excision and the histopathologic review confirmed the diagnosis as an auricular schwannoma. Characteristic immunohistochemical findings may be helpful in differential diagnosis of other tumors. Herein, we present with a literature review a rare case of auricular schwannoma following a trauma.
