High prevalence of loss of Claudin‐18 expression in invasive non‐mucinous lung adenocarcinoma: Potential diagnostic implications in routine practice

Histopathology, Volume 89, Issue 1, Page 81-97, July 2026.
Loss of Claudin‐18 (Cldn18) expression is a frequent and specific feature of non‐mucinous lung adenocarcinoma (NM‐LUAD). Cldn18 immunohistochemistry may serve as an ancillary tool for distinguishing malignant from non‐neoplastic alveolar epithelium, as well as for differentiating NM‐LUADs with mucin production from M‐LUADs, particularly in small or ...
