Photomicrographs of sections stained with selected histochemical methods and microscopy in polarized light for the visualization of hyaline ring granulomas in the omental adipose tissue. a PAS-positive staining of plant matter (arrowhead) and hyaline structures (arrow) surrounded by the connective and adipose tissues. PAS, bar 50 μm. b Most hyaline ring-like structures stained blue with alcian blue. Bar 20 μm. Insets plant cells stained blue, partially lignified and stained magenta by AB. Bar 20 μm. c PAS-positive diastase-resistant staining (PASD) of plant material (arrowhead) associated with the presence of cellulose and hyaline structures (arrow). Bar 50 μm. d Plant particles showing birefringence under polarized light. The same plant structure is presented in Fig. 1d. Bar 20 μm
