Red Blanchable : Erythroderma

A 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 (ie, redness) is due to increased blood flow, not leakage of blood into the skin, as in purpura.
