- Increased white blood cell count (neutrophil leukocytosis)
- Skin biopsy: shows in depth many neutrophil granulocytes that are a type of white blood cell (neutrophil dermatosis) and disturbed cells (leukocytoclastic), as well as edematous endothelial cells in blood vessels (vasculitis)
Course of disease
One or more red and tender knots in or under the skin that increase in size and last for several weeks. Skin changes may also have blisters (pustules), ulcers (ulcers) and may fade in the center. Can sometimes look like pyoderma gangrenosum
