Abstract
This article represents the first reported case in the external auditory canal of epithelioid fibrous histiocytoma (EFH), a rare benign cutaneous epithelioid neoplasm. Immunostaining revealed uncommon negative staining for anaplastic lymphoma kinase (ALK) expression. This case and literature review outline the diagnostic strategy for this highly unusual neoplasm.
