Table 1 Characteristic findings suggestive for necrotizing fasciitis. Typical findings that can indicate necrotizing fasciitis during incision biopsy for macroscopic findings and findings on the fresh frozen section and Gram staining
From: Triple diagnostics for early detection of ambivalent necrotizing fasciitis
Macroscopy | Fresh frozen section | Gram stain |
|---|---|---|
