Do the same infants who develop seborrheic dermatitis also develop atopic dermatitis?

EVIDENCE-BASED ANSWER Infants with infantile seborrheic dermatitis (ISD) are more likely to develop infantile atopic dermatitis (IAD) than infants without ISD (SOR: C, case series compared with historical controls). Similarly, infants with IAD are more likely to have had a history of ISD earlier in life than infants without IAD (SOR: B, case control study).
