Aims Pulmonary peripheral glandular papilloma (GP) and mixed squamous cell and glandular papilloma (MP) have very similar histological features to pulmonary ciliated muconodular papillary tumour (CMPT)/bronchiolar adenoma (BA). The underlying genetic relationships between GP/MP and CMPT/BA have rarely been characterised. We aimed to reveal the relationship between them. Methods and results We performed a clinicopathological review and next‐generation sequencing (NGS) study of two GPs and five MPs. Histologically, GPs/MPs showed similar cellular and architectural features to CMPTs/BAs, such as bilayered epithelium, bronchiole‐associated lesions and skipping (discontinuous) growth pattern. One MP showed partial and inconspicuous endobronchiolar growth and more glandular structures, which was very similar to the appearance of CMPT/BA. BRAF V600E mutation was detected in four papillomas (57.1%, one GP and three MPs). Conclusions Overlapping morphological features and comparable mutation profiles support that peripheral GPs/MPs and CMPTs/BAs are on the same disease spectrum. We propose expanding the concept of CMPT/BA and including GP and MP in the CMPT/BA family.
