2. Definition
• Paleness
• Pallor is the absence of the normal reddish
color of the skin and mucous membranes
imparted by blood in the superficial
vessels.

3. sites
• palpebral conjunctivae (specifically the
anterior rim),
• the oral mucosa (tongue and soft palate)
• palmar creases
• the face in general, although absence of
pallor does not exclude anaemia.
• Nail-bed pallor lacks diagnostic value for
predicting anaemia but is still often
assessed by clinicians.

7. causes
Pallor can be produced by
 edema or
 myxedematous tissue surrounding the
super cial blood vessels,
 vasoconstriction,
 anemia,
 or any combination.

8. CLINICAL OCCURRENCE
• Localized Pallor: Cold exposure, vaso-
constriction (e.g., Raynaud phenomenon),
arterial insufficiency (narrowed lumina,
thrombosis, embolism), edema;

10. • Generalized Pallor: Generalized vaso-
constriction—exposure to cold, severe
pain, hypoglycemia, volume depletion or
low cardiac output states;

11. • Chronic Pallor: Normal in some persons,
anemia, renal failure (anemia may
contribute);
• Paroxysmal Pallor: Apneic periods in
periodic breathing, hypertensive periods
rom pheochromocy-toma, vertiginous
periods in Ménière disease, migraine,
syncope;

12. • Obscuration of Skin Vessels: Edema,
myxedema (anemia may contribute),
scleroderma.

13. Clinical grading of pallor
• Mild: pallor of conjunctiva and/or mucous
membrane.
• Moderate: pallor of conjunctiva and/or
mucous membrane + pallor of skin.
• Severe: pallor of conjunctiva and/or
mucous membrane + pallor of skin + pallor
of palmar creases.
