Background. Mucoepidermoid carcinoma of the thymus is an extremely rare malignant mediastinal neoplasm. Case. We herein report the case of an asymptomatic 29-year-old man with mucoepidermoid carcinoma of the thymus. Chest radiography revealed an anterior mediastinal mass. Computed tomography of the chest demonstrated multiple 62×38×74 mm cystic masses with a focally-enhanced solid portion. Tumor resection was performed, and the pathological diagnosis was mucoepidermoid carcinoma of the thymus with a thymic cyst. Conclusion. We experienced a case of mucoepidermoid carcinoma of the thymus with a thymic cyst. At the time of writing, the patient remains alive without recurrence at 16 months after surgery.
