ABSTRACT
A 76-year-old man was admitted to our hospital with left-side pneumothorax and a solitary pulmonary nodule. The pneumothorax was not improved by drainage, so we performed a left upper lobectomy, both to treat the pneumothorax and to diagnose the nodule. A histological examination of the nodule showed choriocarcinoma with TTF-1 positive adenocarcinoma. Because we found no other primary lesion, we diagnosed primary pulmonary choriocarcinoma. The patient declined to undergo chemotherapy. At 47 days postoperation, he suffered rupture of a metastatic liver tumor and died from the recurrence. Despite its rarity, primary pulmonary choriocarcinoma should be differentially considered in appropriate cases because it requires early diagnosis for a good outcome.
