Coexistence of Alopecia Areata and Seborrheic Dermatitis: A Case Report

Alopecia areata is an autoimmune hair disorder that causes bald patches. AA occurs at all ages with a slightly greater tendency in women. Diagnosis is usually clinical but in atypical cases such as ophiasis, supporting examinations such as trichoscopy or skin biopsy can be performed. Seborrheic dermatitis (SD) is an inflammatory skin disease with scales in areas full of sebaceous glands such as the scalp. Factors that play a role in the pathogenesis of SD include decreased immunity and the role of Malassezia. The diagnosis of SD is usually based on clinical. SD and AA can occur alone or together. In this report, a 44-year-old man came with complaints of patchy hair loss on the scalp for four years accompanied by itchy and scaly red patches on the scalp in the last one month. Based on the history and physical examination, the diagnosis of alopecia areata and seborrheic dermatitis was established. Intralesional corticosteroids, a combination cream of clobetasol and ketoconazole, and loratadine is given. After one week, improvement was seen with the disappearance of scales redness, and hair growth within four weeks of treatment. In conclusion, the treatment performed showed good results to overcome both conditions.
