[Mucoepidermoid carcinoma with high level of serous carcinoembryonic antigen; report of a case].
We reported a case of mucoepidermoid carcinoma with a high level of the serum CEA. A 38-year-old woman was admitted because of abnormal chest shadow. Bronchoscopy revealed polypoid tumor occluding the lumen of right B3 bronchus. Bronchoscopic biopsy suggested a diagnosis of tubular adenocarcinoma. Chest computed tomography (CT) confirmed the mass in the right upper lung field and the swelling of right bronchial lymph node. The CEA level of serum elevated at 12.4 ng/ml. A right upper and middle lobectomy with mediastinal lymph nodes dissection was performed on August 26, 2003. Histopathologically, the polypoid tumor was a low grade mucoepidermoid carcinoma with partially extrabronchial extension. However, no lymph nodes metastasis were noted. The cytoplasms of about 45% of tumor cells showed positive for anti-CEA monoclonal antibody. Pathological stage was IB (T2N0M0). Seventeen months has passed with no evidence of recurrence and the CEA level of serum was in the normal range.
