Figure Lengend Snippet: Histological and immunohistochemical features of the ALK‐positive INMA cases (A) Examples of weak or strong ALK positivity (middle and right), with the left panel demonstrating negative staining. (B) H&E‐stained sections demonstrating histological patterns: lepidic (left), acinar (middle), and papillary (right). (C) Representative H&E‐stained sections showing cribriform (left), micropapillary (middle), and complex glandular (right) patterns. (D) H&E staining of an example of solid growth pattern (left); IHC staining shows tumor cells positive for TTF‐1 (middle) and negative for p40 (right). (bar = 100 μm). ALK, anaplastic lymphoma kinase; H&E, hematoxylin and eosin; IHC, immunohistochemistry; INMA, invasive non‐mucinous adenocarcinoma.
