January Case of the Month

Clinical History: A PET-positive 1.5-cm solitary central pulmonary nodule was resected in a 67 year-old woman (non-smoker). The clinical suspicion was malignancy. Macroscopically, the nodule was tan-white and well demarcated. As depicted in Figure 1 (H&E) and Figure 2 (EvG), histologically the nodule was predominantly endobronchial with minimal alveolar extension and consisted of a papillary tumor. There was an acute inflammatory infiltrate between the fibrovascular cores. The surrounding lung parenchyma showed mucostasis and lympho-follicular inflammation, which could be attributed to a post-obstructive complication. The fibrovascular cores were lined by glandular epithelium with pseudostratified ciliated and non-ciliated cuboidal to columnar mucin-filled cells (Figure 3) and interspersed areas of acanthotic squamous epithelium (Figure 4, H&E; Figure 5, p40). There was no atypia, karyorrhexis or necrosis.
