OBJECTIVES Pure bronchioloalveolar carcinoma (BAC) is considered the early stage of lung adenocarcinoma, and is even regarded as lung adenocarcinoma in situ. This study was designed to investigate the differences in the gene expression of pure BAC and that of adenocarcinoma with bronchioloalveolar features and explore the mechanism of BAC progression to adenocarcinoma with bronchioloalveolar fe...

Discussion Bronchioloalveolar carcinoma is one of the four recognised subtypes of lung adenocarcinoma. The dramatical increase in the incidence of lung adenocarcinoma in the last decade, being in some series the most frequent histological type among all lung malignancies, seems to be mostly due to the raising incidence of bronchioloalveolar carcinoma. Its distinctive pathological feature is gro...

This is a brief case report of invasive multicentric mucinous adenocarcinoma presented at a rather young age with bronchorrhea and persistent consolidation that ended up with the patient demise; nevertheless, we demonstrate relevant radiological and pathological features with emphasis on the new classification of bronchioloalveolar carcinoma, a term that should no longer be in use.
