Synchronous double primary cancers of lung and liver

Although reports of multiple primary malignant tumors have increased recently, cases of synchronous double primary tumors of lung and liver are rare. A 73-year-old man suffered from chronic cough. His chest x-ray showed segmental atelectasis of the right upper lobe. Bronchoscopy revealed a mass occluding the orifice of the anterior segmental bronchus of the right upper lobe, and a biopsy showed a squamous cell carcinoma A synchronous hepatic mass was found by ultrasonography. However, F18-FDG-PET showed no evidence of a distant metastasis. The liver biopsy revealed a hepatocellular carcinoma A right upper lobe lobectomy and a sleeve resection were performed for the lung cancer, and radiofrequency ablation was performed for the hepatocellular carcinoma.
