Atopic eczema, or atopic dermatitis, affects up to 20% of children and often presents in infancy. Cow’s milk allergy can also manifest as eczema and gastrointestinal (GI) symptoms. Food allergy should be suspected if there is a clear history of a reaction to a food in infants with moderate to severe eczema not responding to standard treatment, in infants with very early onset eczema (under 3 months) and those with GI symptoms. Seborrhoeic dermatitis is often an early manifestation of atopic eczema. Naevus simplex is a common congenital capillary malformation occurring in up to 40% of newborns. Port wine stains are less common, affecting about 0.3% of infants.
