Rash diagnosis algorithm
Calculation requires an answer to the question:
"Fluid filled or solid?"
Fluid filled or solid?
If fluid-filled, is it clear or pustular?
Is it red?
Is it scaling?
If non-red, what color is it?
If non-scaling and red, is it dome-shaped or flat-topped?
If red and scaling, is there epithelial disruption (erosions, weeping, crust, fissures, or yellow scale)?
