Pleomorphic adenoma (PA), originally called mixed tumour, is the most common neoplasm of the salivary glands. It is usually a benign, slow-growing and well-circumscribed tumour. However, PA may occasionally give rise to metastases that usually occur after a previous recurrence. These tumours display benign histological features in both primary tumours and metastases. Such tumours have been termed metastatic PA or metastatic mixed tumours. We report a case of metastatic PA of the submandibular gland with metastasis to the cervical lymph nodes.
多形性腺瘤（PA），最初称为混合瘤，是唾液腺最常见的肿瘤。它通常是一种良性、生长缓慢且边界清晰的肿瘤。然而，PA偶尔可能会发生转移，通常在先前复发后出现。这些肿瘤在原发性肿瘤和转移灶中均表现出良性组织学特征。这类肿瘤被称为转移性PA或转移性混合瘤。我们报告一例下颌下腺转移性PA伴颈部淋巴结转移的病例。
