title: [Hidradenoma of the external acoustic meatus: ceruminoma].
abstract: Benign tumour originating from the ceruminous glands of the external auditory meatus are quite rare and present similar histological features to sweat gland tumours elsewhere. The paper reports the case of a nodule in the external auditory meatus diagnosed as a myoepitheliomatous-type hidradenoma . Three histological forms of benign ceruminous gland tumours are recognised: the myoepitheliomatous, cribriform and mixed salivary type. Currently, the term hidradenoma of the external ear is preferred.
