Keratosis punctata of the palmar creases. 
Nineteen cases of keratosis punctata of the palmar creases are presented.  This entity, currently regarded as a variant of keratosis punctata of the palms and soles, is seen almost exclusively in blacks.  It is benign, mostly asymptomatic, and sometimes familial without any sex predilection.  The clinical lesions are pits and keratotic papules confined to the creases of the palms and volar surfaces of the fingers.  The soles are rarely affected but a new finding reported here is the involvement of the side of feet in eight of the nineteen cases.
