[Surgery on cylindroma of the external auditory canal].

Cylindromas are rare benign tumours arising from sweat glands in the skin. They occur as multiple tumours (as in Brooke-Spieglers syndrome) and solitary tumours. They most commonly occur on the head and neck and may appear in the external auditory canal causing hearing loss. We present such a case and discuss its pathological and clinical features. The patient was treated with local surgical excision.
