Dermatite séborrhéique

Seborrheic dermatitis is a common facial dermatitis that affects 1 to 3 % of the adult population. The incidence of the disease is higher in some diseases such as HIV infection, Parkinson's disease or mood disorders. This dermatitis presents as red, flaking patches of skin located where seborrhoea activity is maximal. Two mechanisms are important to understanding seborrheic dermatitis: Malassezia yeasts and seborrhoea. Most of the time, topical treatment is successful. Controlled trials have demonstrated the efficacy of ketoconazole, ciclopirox olamine and lithium gluconate.
