The present WHO classification (3rd edition) has 2 critical problems. Bronchioloalveolar carcinoma is classified in the invasive adenocarcinoma category, even though its 5-year survival rate is 100%. Since the WHO adopted "mixed subtype" in invasive adenocarcinoma classification, over 90% of invasive adenocarcinoma was diagnosed as "mixed subtype". Recently, the IASLC proposed a multidisciplinary adenocarcinoma classification. "Adenocarcinoma in situ" is added in preinvasive lesion. Invasive adenocarcinomas are divided into 5 histological subtypes, based on their predominant structure.
key words: Adenocarcinoma in situ, Minimally invasive adenocarcinoma, Bronchioloalveolar carcinoma, Lepidic growth, Micropapillary growth
