Both ultrasonic scan and CT scan showed that the lower half of left pleural cavity was occupied by the polycystic structure. The echo-guided percutaneous needle aspiration yealded 1500ml of intracystic fluid. Laboratory studies revealed increased CEA value of 157.3ng/ml in aspirated fluid and normal CEA level in serum. On left thoracotomy, thin-walled polycystic tumor measuring 25×15×15cm, in which the small solid mass protruded, was successfully removed. Histologically, the wall of the cyst and the surface of solid mass were covered with stratified squanous epithelium with sebaceous gland and hair follicles. Thymic tissue, bronchial structure, intestinal structure and pancreatic tissue which contained mainly exocrine elemant were also found in the solid tumor. CEA stained by PAP method revealed that pancreatic ductal epithelium was a only tissue that had CEA activity, and its exocrine secretion seemed to result in high level of CEA in cystic fluid.
