Abstract

Mixed squamous cell and glandular papilloma is a rare pulmonary neoplasm typically occurring in the central lung area. Herein, we report a case of peripherally located mixed papilloma in a 54-year-old man with a complaint of dyspnea. Chest computed tomography demonstrated an infiltrative peripheral lung mass in the right middle lobe, measuring 1.5 cm in diameter. The resected lung tumor had papillary configuration lined by both squamous cell epithelium and mucin-containing glandular epithelium. The papillary stroma showed a fibrovascular core with inflammatory infiltrates. p63 immunostaining was positive in basal and parabasal tumor cells in papillary fronds.
