Characteristics of splenic arteriolar hyaline with Azan stain. A: Representative images of 3 tinctorial patterns (upper panels, HE stain; lower panels, Azan stain; scale bars: 50 μm). Similar hyaline depositions on HE stain present 3 different staining patterns with Azan stain: red, blue, and a combination of the two. B: The number of cases demonstrating each tinctorial pattern among 82 forensic autopsy cases. The 3 patterns coexisted in various proportions in each case.
