Invasive mucinous adenocarcinoma of lung is a subtype of invasive adenocarcinoma of the lung. It was formerly known as mucinous bronchoalveolar carcinoma.
Mucinous carcinomas originate from columnar mucus-containing cells (c.f. non-mucinous tumours which arise from Clara cells or type 2 pneumocytes). Mucinous carcinomas are thought to be more likely to be multicentric and tend to have a worse prognosis than non-mucinous types 3.
