Eccrine acrospiroma of the external auditory canal.

Tumors of the external auditory canal include osteomas, ceruminomas, sebaceous cysts, keloids, basal cell carcinomas, squamous cell carcinomas, and, in rare cases, eccrine acrospiromas. We describe an eccrine acrospiroma arising from the distal external auditory canal, which was associated with decreased hearing on the affected side. Surgical resection of the tumor resulted in improved hearing.
