From: Solitary glandular papilloma of the peripheral lung: a report of two cases
Imaging and pathological findings in Case 2. a) Chest computed tomography (CT) shows a 1.0 × 0.8-cm nodule in segment 9 of the left lung (arrowhead). b) Low-power histologic view of the resected tumor (hematoxylin-eosin staining). The tumor is composed of a fibrovascular core and papillomatous fronds lined by pseudostratified columnar epithelium. c) High-power view of b (hematoxylin-eosin staining). The pseudostratified columnar epithelium consists of ciliated columnar cells and numerous mucous cells, with no cytologic or architectural atypia.
