Pleomorphic adenoma (PA) is by far the most common salivary gland tumor. It is well known that PA can undergo malignant transformation. However, in rare occasions it can metastasize preserving its benign phenotype. Metastasizing pleomorphic adenoma (MPA) constitutes an extremely rare tumor. Here we are reporting an unusual MPA affecting the mandible that was preceded by a submandibular gland pleomorphic adenoma.
多形性腺瘤（PA）是迄今为止最常见的涎腺肿瘤。众所周知，PA可发生恶变。然而，在罕见情况下，它可在保持良性表型的同时发生转移。转移性多形性腺瘤（MPA）是一种极其罕见的肿瘤。在此，我们报告一例累及下颌骨的罕见MPA，其之前存在下颌下腺多形性腺瘤。
