Summary

• Chronic inflammatory skin disorder characterised by erythematous and greasy scaly patches.
• Patches are red, inflamed, and pruritic with micaceous scale. Circumscribed patches are found on the scalp, glabella, nasolabial fold, posterior auricular skin, and anterior chest.
• Variable course that seldom completely subsides. An infant form (cradle cap) usually resolves within the first few months of life.
• Tends to flare with stress. The adult scalp form is commonly termed dandruff or pityriasis capitis.
• Topical agents (corticosteroids, antifungals, calcineurin inhibitors, shampoos, and tar preparations) are used for mild and limited disease.
• Oral antifungals are reserved for severe and recalcitrant forms.
