Pleomorphic adenomas are benign salivary gland tumours that mostly affect the superficial lobe of the parotid gland. They are commonly found incidentally as rigid, unilateral, painless masses, growing gradually. Ninety percent of pleomorphic adenomas occur in the parotid gland, while 10% appear in minor salivary glands. The incidence of the parotid tumour is 2.4 in 10,000 per year. We describe the case of a 53-year-old woman presenting with a gradually growing retroauricular mass on the left side of the ear. Radiographic imaging and histopathological findings suggested a pleomorphic adenoma of the parotid gland. The tumour was removed and the patient recovered well upon follow-up.
多形性腺瘤是良性涎腺肿瘤，主要影响腮腺浅叶。它们通常作为坚硬、单侧、无痛的肿块偶然被发现，逐渐生长。90%的多形性腺瘤发生在腮腺，10%发生在小涎腺。腮腺肿瘤的发病率为每年每 10000 人中 2.4 例。我们描述了一位 53 岁女性的病例，她在左耳后逐渐出现一个生长的肿块。影像学和组织病理学检查提示为腮腺多形性腺瘤。肿瘤被切除，患者在随访中恢复良好。
