Adenoid Cystic Carcinoma with Sebaceous Differentiation and MYB::NFIB Fusion Arising in the External Auditory Canal
摘要
Adenoid cystic carcinoma arising in the external auditory canal is rare, and even rarer are cases with sebaceous differentiation mimicking sebaceous carcinoma. This case with clinical, radiologic, gross, and histologic images exemplifies an unusual occurrence of adenoid cystic carcinoma in the external auditory canal with sebaceous differentiation, confirmed by MYB::NFIB fusion.
