Currently, the term bronchioloalveolar carcinoma should correctly be used only to diagnose a small, purely lepidic cancer that does not invade into the alveolar interstitium or other tissues.
A final diagnosis of bronchioloalveolar carcinoma (BAC) was made.
One of the most important changes in terminology is the designation of neoplasms previously classified as bronchioloalveolar carcinoma as adenocarcinoma in situ to emphasize that they tend not to spread to regional lymph nodes or to metastasize.
The diagnosis of bronchioloalveolar carcinoma was made after a fibreoptic bronchoalveolar lavage.
These relate to the discontinuation of the terms bronchioloalveolar carcinoma and adenocarcinoma, mixed subtype, as well as the introduction of micropapillary as a new histologic subtype, the term lepidic pattern for the former bronchioloalveolar carcinoma growth pattern, and the specific term invasive mucinous adenocarcinoma for overtly invasive tumors previously classified as mucinous bronchioloalveolar carcinoma.
6) Bronchioloalveolar carcinoma shows morphologic overlap with AAH, and it has been suggested that these lesions are part of the continuum in the adenoma-carcinoma sequence of the development of lung adenocarcinoma.
Comparison of the immunophenotypes of signet-ring cell carcinoma, solid adenocarcinoma with mucin production, and mucinous bronchioloalveolar carcinoma of the lung characterized by the presence of cytoplasmic mucin.

The cytologic differential diagnosis includes well-differentiated adenocarcinoma, particularly bronchioloalveolar carcinoma, and the similarities between the two have led to misdiagnosis of malignancy.
