Pleomorphic adenoma comprises about 80% of the benign salivary gland tumours and is characterised by a slow growth and a clinically benign course. This tumour is known to occur at various other anatomical locations apart from the major salivary glands. Case reports of this tumour arising from the nasal septum, tongue, turbinate, upper lip, lungs, trachea and lacrimal glands have been found in the literature. But case reports of pleomorphic adenoma from the external auditory canal have been extremely few.
多形性腺瘤约占涎腺良性肿瘤的80%，其特点是生长缓慢，临床过程呈良性。已知该肿瘤除主要涎腺外还可发生于其他各种解剖部位。文献中已发现有鼻中隔、舌、鼻甲、上唇、肺、气管和泪腺发生此肿瘤的病例报告。但外耳道多形性腺瘤的病例报告极少。
