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.
起源于外耳道耵聍腺的良性肿瘤非常罕见，其组织学特征与其他部位的汗腺肿瘤相似。本文报告了一例外耳道结节被诊断为肌上皮瘤型汗腺腺瘤的病例。良性耵聍腺肿瘤有三种组织学类型：肌上皮瘤型、筛状型和混合唾液型。目前，外耳道汗腺腺瘤这一术语更为常用。
