Multiple Primary Lung Carcinomas in the Same Lobe.

Multiple primary lung cancers are unusual but important to identify, since the therapy protocol and the prognosis will be different when compare with metastatic tumors. We present the case of a 64-year-old man with synchronous lung tumors of different histo-pathological patterns in the same lobe. Radiological investigation revealed two areas of high-intensity fludeoxyglucose uptake of varying size within the left upper lobe. He underwent left upper lobectomy. Histological analysis confirmed these lesions as adenocarcinoma and moderately differentiated squamous cell carcinoma. [ABSTRACT FROM AUTHOR]
