Abstract

Background  The relationship between infantile seborrheic dermatitis (ISD) and infantile atopic dermatitis (IAD) is controversial.

Methods  Ninety-six children aged 2–12 months diagnosed with atopic dermatitis and a comparable control group of healthy children were evaluated. Demographic data, personal history of ISD and personal or family history of atopy was considered in both groups.

Results  A personal history of ISD was found in 49% of IAD cases and in 17% of controls (P < 0.05).

Conclusions  Our result and those of the literature do not demonstrate a relationship between ISD and IAD. However, a number of cases of AD have an ISD-like clinical picture. It is probable that ISD is a syndrome and not a disease.
