Which stain is commonly used to visualize reticulin fibers in connective tissue?

Explanation:
Reticulin fibers form a delicate, branching network of type III collagen that needs a specialized stain to be seen clearly. The Gomori reticulin stain uses silver to impregnate these fibers, so they appear dark against a lighter background. This makes the fine reticular framework visible and helps evaluate tissue architecture, fibrosis, or cirrhosis patterns. Verhoeff specifically stains elastic fibers, not reticulin. Masson Trichrome highlights collagen but is not optimized for the fine reticular network, and H&E is a general stain that doesn’t reliably reveal reticulin fibers.
