A 63-year-old female with two concurrent primary lung adenocarcinomas, one in the right middle lobe (lesion A) (a) and one in the right lower lobe (lesion B) (b). By CT, lesion A appeared as a pure ground glass opacity (GGO) nodule, and lesion B exhibited a mixed GGO with a lobulated border. Haematoxylin and eosin (H&E) staining (c, d) showed different histological adenocarcinoma types, and the ARMS method (e, f) revealed a 19_del mutation within exon 19 of the EGFR gene in the lower lobe tumour but not in the middle lobe tumour
