What is the primary advantage of combining special stains (e.g., PAS, trichrome, mucicarmine) with routine H&E when evaluating a tissue biopsy?
Show answer and explanation
Correct answer: They reveal specific components—glycogen, mucin, collagen—poorly shown by H&E
Special stains target biochemical or structural components (e.g., glycogen, mucins, collagen) that may not be differentiated clearly on H&E; thus, they complement H&E and enhance diagnostic accuracy, especially in pathologic conditions.
