A case of human chorionic gonadotropin (HCG)-producing squamous cell carcinoma of the lung is reported.A 47-year-old woman was admitted to our hospital with an abnormal shadow on chest X-ray without any symptom.Because of the high titer of HCG (urine HCG;1000IU/L, serum, β-HCG;l5ng/ml) and the past history of hydatidiform mole, it was suspected that the tumor in the left lung was a metastatic lesion from uterus choriocarcinoma.Chemotherapy, simple hysterectomy, and wedge resection of the left lung were performed.However, the resected specimen revealed no abnormalities in the uterine by pathological examination, and a definitive diagnosis of HCGproducing squamous cell carcinoma of the lung was made.
Left pneumonectomy and mediastinal lymphnode dissection were carried out.At 1 year 8 months after the operation, her clinical course is good and she is alive.
