Periorificial and acral dermatitis in a newborn having milk intolerance.
A 2-week-old infant born at 36-week gestation developed diarrhea and metabolic acidosis when he was put on formula feeding. He was treated for sepsis and was screened for metabolic diseases. Blood and cerebrospinal fluid cultures were clear. The diarrhea and metabolic acidosis settled but recurred when formula feeding was resumed. He developed a florid erythematous rash involving the palms, feet, perioral and perineal regions. Zinc deficiency was confirmed and zinc replacement resulted in prompt resolution of the skin rash. The patient was put on Pepti-Junior and remained well. This case illustrates that zinc deficiency must be sought and treated in an infant with a typical rash involving the palms, feet and body orifices.
