Pallor is a pale color of theskin that can be caused by illness, emotional shock or stress, stimulant use, oranemia, and is the result of a reduced amount ofoxyhaemoglobin and may also be visible as pallor of theconjunctivae of the eyes on physical examination.

Pallor is more evident on theface andpalms. It can develop suddenly or gradually, depending on the cause. It is not usually clinically significant unless it is accompanied by a general pallor (palelips,tongue, palms,mouth and other regions withmucous membranes). It is distinguished from similar presentations such ashypopigmentation (lack or loss of skinpigment) or simply a fair complexion.
