Pilomatrixoma of the external auditory meatus.

Pilomatrixoma is a benign skin tumour arising from the outer hair root matrix. It is an uncommon tumour which favours the hair bearing area of the head and neck. The preauricular area is a well documented site, but to our knowledge, there are no reports of a pilomatrixoma arising in the external auditory meatus. We present such a case and discuss the historical background along with its pathological and clinical features.
