Unusual Palm Creases and Unusual Children

Abstract
Inspection of palm creases should be a routine part of the pediatric physical examination. Any variation in the basic configuration should be cause for concern, irrespective of the age of the child. Is the "nor mal" child with an SPC, SL, or other type C palm really normal? Will time or psychologic evaluation uncover an unsuspected abnormality? An otherwise normal infant with palmar crease abnormalities should be considered at risk of developmental problems appearing later.
