Abstract

Seborrheic dermatitis (SD) is a common chronic skin condition characterized by well-defined, salmon-pink, scaly patches and plaques. The disease is mainly found in areas of increased sebum production. SD may be associated with several other chronic conditions such as Parkinson’s disease and AIDS. Changes in sebaceous gland activity and skin microbiota, immune dysregulation, and genetic predisposition play a role in pathogenesis of the disease. Diagnosis is based on the characteristic features and location of the rash. The goal of treatment is to alleviate symptoms and prevent flare-ups, with topical treatment being preferred. However, the precise pathogenesis of SD and its pathogenetic connections with other chronic diseases remain unclear and further research would help improve the diagnosis, treatment, and prognosis of the disease.
