We report a case of pleomorphic adenoma of the parotid with metastasis to the liver, following resection for local recurrence, which has only been described once before. The diagnosis was made by fine needle aspiration and the lesion was resected without complications. The patient is free of disease 4 years later. Histological features of malignancy were not present in any specimens from the original resection, the local recurrence and the metastatic lesion. It is difficult to say which patients with pleomorphic adenoma should be observed for the development of treatable metastases, but metastases have been reported to occur mainly after repeated resections for local recurrences.
我们报告一例腮腺多形性腺瘤，在因局部复发切除后发生肝转移，此前仅有一次相关报道。诊断通过细针穿刺确定，病变切除无并发症。4年后患者无疾病迹象。原发切除、局部复发及转移病灶的所有标本中均未发现恶性组织学特征。很难说哪些多形性腺瘤患者应观察是否出现可治疗的转移，但据报道转移主要发生在因局部复发而反复切除之后。
