Lung, Alveolar/Bronchiolar Epithelium - Hyperplasia - Gallery

Image of alveolar/bronchiolar epithelial hyperplasia in the lung from a male B6C3F1/N mouse in a chronic study
Lung, Alveolar/bronchiolar epithelium - Hyperplasia in a male B6C3F1/N mouse from a chronic study. This low-magnification image shows the distribution of the lesion.

Lung, Alveolar/bronchiolar epithelium - Hyperplasia in a male B6C3F1/N mouse from a chronic study. This lesion occurs adjacent to bronchioles and alveolar ducts.

Lung, Alveolar/bronchiolar epithelium - Hyperplasia in a male B6C3F1/N mouse from a chronic study. Secondary alveolar epithelial hyperplasia associated with inflammation is present at the bronchiolar-alveolar duct junction.
