Polymorphous low-grade adenocarcinoma is an unusual tumor that has been described as occurring in the minor salivary glands, particularly of the palate. To our knowledge, there is only one previous report that has documented the occurrence of this type of lesion in the major salivary glands. We describe an elderly patient with polymorphous low-grade adenocarcinoma arising in the parotid gland that was originally diagnosed as carcinoma ex pleomorphic adenoma.
多形性低度恶性腺癌是一种罕见的肿瘤，曾被描述为发生于小唾液腺，尤其是腭部。据我们所知，之前仅有一份报告记录了这种类型的病变发生于大唾液腺。我们描述了一位老年患者，其腮腺发生多形性低度恶性腺癌，最初被诊断为多形性腺瘤恶变。
