From: Solitary glandular papilloma of the peripheral lung: a report of two cases
Imaging and pathological findings in Case 1. a) Chest computed tomography (CT) shows a 0.8 × 0.8-cm nodule in segment 9 of the left lung (arrow). b) Low-power histologic view of the resected tumor (hematoxylin-eosin staining). The tumor consists of a fibrovascular core and papillomatous fronds lined by pseudostratified columnar epithelium. c) High-power view of b (hematoxylin-eosin staining). The columnar epithelium consists of ciliated columnar cells, goblet cells and basal cells with no cytologic or architectural atypia.
