摘要：

Myoepithelial carcinoma, arising in a recurrent or in a pre-existing pleomorphic adenoma of the parotid gland is an extremely rare cancer. We herein report the case of myoepithelial carcinoma occurring in a recurrent pleomorphic adenoma, which showed a high metastatic potential. A 53-year-old male, who had undergone a superficial parotidectomy of the pleomorphic adenoma 2 years previously, presented with recurrent parotid swelling and with multiple coin lesions in the lung. A total parotidectomy and a thoracoscopic biopsy of the lung lesion revealed both lesions to be myoepithelial carcinoma. The patient died about 12 months later despite undergoing intensive chemotherapy. (C) 2008 Elsevier Ireland Ltd. All rights reserved.
