A patient is presented whose large cell carcinoma of the lung was detected by an elevated β subunit human chorionic gonadotropin (HCG) titer 2 years after undergoing chemotherapy and remission for metastatic trophoblastic disease. The secretion of HCG was low (3.48 to 14.18 mIu/ml) and intermittent. Roentgenologic appearance of the lesion occurred 4 months after secretion of HCG was detected. HCG-producing tumors of nontrophoblastic origin should be considered when low titers are detected after complete remission of trophoblastic disease.
