An example of multifocal GG/L lung cancer, a kind of lung adenocarcinoma subtype which often occurred in Asian women or non-smoker recently according to the IASLC Lung Cancer Staging Project in 2016. A 61-year-old woman had a 2.8 cm part-solid nodule in LUL, and another one pure GGN nodule 1.4 cm in RLL. The patient underwent sequentially video-thoracoscopic wedge resection of RLL and LUL. Further pathologic report demonstrated invasive adenocarcinoma in LUL, and adenocarcinoma in situ in RLL. Synchronous multiple primary lung cancer was diagnosed according to the diagnostic criteria proposed by Martini and Melamed. Abbreviations: RLL = right lower lobe; GGN = groundglass nodule; LUL = left upper lobe
