Solitary Pulmonary Mixed Squamous Cell and Glandular Papilloma - A Brief Case Report

초록

Pulmonary mixed squamous cell and glandular papillomas are extremely rare-only a few cases have been reported worldwide. We report a case of mixed squamous cell and glandular papilloma that presented as a solitary pulmonary nodule in a 53-year-old man. The tumor was located in the peripheral small bronchus of the posterobasal segment of the right lower lobe. Microscopically, the tumor was composed of papillary structures lined by squamous and glandular epithelium with mucous material. The fibrovascular cores showed lymphoplasmacytic infiltrates.
