There are many case reports about double primary cancers, but few about double primary cancers of the liver and the lung. We experienced a case of subsegmentectomy of the liver and right upper lobectomy of the lung for synchronous double primary cancers of the liver and the lung at the same time. A 62-year-old man complained of a sense of general fatigue. Abdominal computed tomography (CT) revealed a space-occupying lesion in the S₅ area of the liver. Ultrasonography (US), magnet resonance imaging (MRI) and hepato-arteriography were performed. Hepatocellular carcinoma was suspected from several examinations. On admission, a coin lesion was revealed in the right upper pulmonary field by chest X-ray. Chest CT and chest X-ray tomographies were studied. Squamous cell carcinoma of the lung was suspectd. Our final diagnosis of this case was synchronous double primary cancers of the liver and the lung. We performed right upper lobectomy of the lung and S₅ subsegmentectomy of the liver at the same time. Histologically, the cancers were moderately differentiated squamous cell carcinoma and Edmondson-II hepatocellular carcinoma. Recently double primary cancers have increased, and many reports discuss their etiology and their treatment. We must determine the stage of each cancer and general condition of the patient, and select the method and order of the operation. We conclude that the synchronous double primary cancers should be operated on radically at the same time if possible.
