Abstract

Gray patch type of tinea capitis is one of clinical manifestations of dermatophytosis in scalp and hair that usually occurs in tropical areas such as Lombok, mainly taking place in 6-month-old to 12-year-old children and could cause hair loss. The risk factors are direct contact with microorganisms from animals, humans, and soil. In addition, indirect contact with fomite and inappropriate use of topical corticosteroid. We are reporting two cases, two siblings, a 7-yearold girl and 11-year-old boy with gray patch tinea capitis. The risk factors in these two patients were exposure to cats, sleeping in the same bed, and the use of betamethasone valerate cream. On Wood's lamp examination, a yellow-green fluorescent was found and on 20% potassium hydroxide (KOH) examination, an ectothrix spore was found. The systemic therapy given to both patients was ultramicrosize griseofulvin, vitamin D3, cetirizine, and topical therapy, which is terbinafine cream 1%. Identification of risk factors in this case is the main thing in determining effective and efficient management.
