Adenocarcinoma of Lung (Mucin Stain) • This is a view of a mucicarmine stain on an adenocarcinoma of the lung. • Despite the lack of central lumens in the nests of neoplastic cells (black arrows)there is vivid intracellular mucin staining (yellow arrows to magenta globules) . • Such extensive positivity identifies this neoplasm as an adenocarcinoma.
