Combined occurrence of both congenital pulmonary airway malformation (CPAM) and esophageal cyst is rare and its diagnosis requires a carefully pathologic examination. Differential diagnoses include malignant neoplasms of pulmonary origin, pulmonary inflammatory pseudotumor, bronchogenic cysts and other congenital lesions of esophagus and lung. This paper presented a rare case report of a 31-year-old adult male with combined type III CPAM and an esophageal cyst. The patient was misdiagnosed and treated for pneumonia and tuberculosis before being admitted to our hospital. To eliminate symptoms and make an accurate diagnosis, the patient received a right upper lobectomy and a complete excision of the cyst lesion via thoracotomy. The patient remained uneventful during 1-year follow-up observation.
