FIGURE 4.
Paraffin section hematoxylin and eosin (H&E) slides. While recognizable in cryosections, a variety of systemic and infectious diseases may be more readily detected in H&E-stained paraffin sections of muscle biopsies. (A) Vasculitis, in this case eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome). (B) Amyloidosis in a patient with monoclonal gammopathy. (C) Trichinella myopathy (Trichinellosis). The scale bar in panel C is 200 µm for panels A and C; 50 µm for panel B.
