Sebaceous epithelioma is a rare skin tumor with sebaceous differentiation. Histopathologically, it is composed of undifferentiated basaloid cells, differentiated sebaceous cells and transitional cells. Our patient was an 80 year-old man with an asymptomatic tumor in the right external auditory canal. The tumor was 1.2×0.8cm and had a stem at the lower wall of the external auditory meatus and could be completely resected. During a one-year follow-up period, there was no recurrence of the tumor.
Key words : sebaceous epithelioma, external auditory canal
