Pallor describes paleness of the skin and mucous membranes. It may be a result of reduced blood flow, abnormal pigmentation or anaemia.
Pallor is best assessed by examining the conjunctivae and mucous membranes. It is a poor index of the extent of anaemia.
Pallor due to abnormal pigmentation may be considered in terms of:
- generalized hypomelanosis
- white patches on the skin, or leukoderma
