Abstract

Epithelial-myoepithelial carcinoma (EMC) is a rare malignant salivary gland neoplasm accounting for approximately 1% of all salivary gland tumors. EMC is typically found in the parotid gland. In this report, we present a case of double cancer with EMC in the submandibular gland and lung cancer.<br>The patient was a 57-year-old woman. She had been aware of a left submandibular mass for ten years. An elastic and hard thumb-sized mass in the submandibular region was palpated. CT examination revealed neoplastic lesions in the left submandibular gland and the left upper lung. In April 2008, based on the diagnosis of tumor of the left submandibular gland and metastatic lung cancer in the left upper lobe, excision of the submandibular gland tumor was performed. Subsequently, a left superior lobectomy was performed in the Department of Thoracic Surgery in our hospital in May 2008. Postoperative microscopic examination revealed that the submandibular tumor was characterized by a bilayer structure composed of outer clear myoepithelial cells and inner ductal cells. The pathological diagnosis was EMC. The lung tumor was diagnosed as bronchioloalveolar carcinoma, and the two lesions were independent of each other.<br>The postoperative course was uneventful. The patient has been well and free from the disease for 3 years postoperatively.
