Abstract

A 78-year-old man was admitted to our hospital as a result of dyspepsia with a 2-month duration. Upon admission, the laboratory data showed a marked elevation in amylase activity in both the serum and urine. The pancreas and salivary glands were considered unlikely to have any clinical involvement in the hyperamylasemia. The chest PA revealed a right side pleural effusion, and the chest CT showed a heterogeneous enhancing mass on the subcarinal area. The patient was diagnosed bronchoscopically with a poorly differentiated squamous cell carcinoma. The amylase isoenzyme patterns indicated the salivary types, but lung cancer was strongly suspected to be the source. In most cases, lung cancers with hyperamylasemia have been diagnosed as adenocarcinomas. A squamous cell carcinoma is quite rare. We report an interesting case of squamous cell lung cancer with hyperamylasemia
