Masson's Trichrome Stain

A stain used to highlight the collapse of liver plate architecture, distinguishing between normal and abnormal tissue structures in liver mass assessment.

Reticulin Stain

Helps distinguish between liver cell necrosis and fibrosis; disrupted reticulin fibers indicate necrosis, while preserved fibers indicate fibrosis.

Schiff's Reagent Stain

Highlights bile in tissues, showing a pink to red color.

Hematoxylin Stain

Used as a counterstain to bile stain, highlighting nuclei and other structures in blue.

Toluidine Blue Staining

A basic dye that stains acidic structures like mast cell granules, appearing purple due to metachromasia.

Acidified Toluidine Blue Solution

Enhances staining of mast cell granules by increasing the dye's affinity for acidic structures, aiding in highlighting granule contents effectively.

Masson's Trichrome Technique

A staining process involving Weigert's iron hematoxylin, Biebrich scarlet-acid fuchsin, and aniline blue to differentiate tissue components like collagen, muscle fibers, and connective tissue in histological analysis.
