The patient's mother thinks the eruption may be pruritic because the infant is not sleeping well and is constantly rubbing his hands and feet. The mother describes the lesions as "coming in waves." Other members of the family are not itching. 

What is the most likely diagnosis?

A. Acropustulosis of infancy

B. Congenital syphilis

C. Scabies

D. Sucking blisters

E. Contact dermatitis





The correct answer is A. 

The infant has acropustulosis of infancy. Acropustulosis of infancy is a very pruritic eruption on the palms, soles, and lower extremities.
