Cavitating Adenocarcinoma and Squamous Cell Carcinoma in the Same Lobe of the Lung / 대한흉부외과학회지

Synchronous primary lung cancers in the same lobe are rare. Cavitating adenocarcinoma as single lung lesion is unusual. We experienced cavitating adenocarcinoma and squamous cell carcinoma in the same lobe of the lung. The patient was a 64-year-old male with chief complaints of hemoptysis. CT scan showd a central mass in right upper lobar bronchus, obstructive pneumonia, and lung abscess in the right upper lobe. Pathologically, the central mass was a 2.3x1x1 cm sized squamous cell carcinoma, and lung abscess was revealed as a 3x2x2 cm sized adenocarcinoma. The patient was discharged without any specific problem after right peumonectomy.
