Adenocarcinoma of Lung (Mucin Stain)

Adenocarcinoma of Lung (Mucin Stain) • This is a view of a mucicarmine stain on an adenocarcinoma of the lung. • The magenta granular staining (yellow arrows) seen in most neoplastic cells is mucin. • This finding must result in a diagnosis of adenocarcinoma, which in this case is poorly differentiated.
