• Generalized blanchable redness of the skin that may be associated with desquamation.
  • Desquamation is a normal process in which the cornified (outermost) layer of the epidermis is sloughed in fine scales or sheets.
  • Erythema and erythroderma will blanch because the color (“redness”) is due to increased blood flow, not leakage of blood into the skin, as in purpura.
