ABSTRACT
Tinea faciei is a rare dermatophyte infection of the face that most often appears as a facial rash, followed by patches of small and raised bumps. Since it is uncommon in children and has similar rash patterns with various skin diseases, it is likely to be misdiagnosed as herpes simplex infection, contact dermatitis, disc-shaped lupus erythematosus, acne, and atopic dermatitis. In this case, siblings aged 3 and 4 were hospitalized due to skin rashes that occurred after traveling to Vietnam, and were administered antiviral drugs and systemic steroids under suspicion of herpes simplex infection with atopic dermatitis. Despite administration of these drugs, skin lesions did not show improvement. Serum beta-Dglucan assays were elevated in both patients, and after approximately 2 weeks, Trichophyton interdigitale was cultured in the older sister's skin fungal culture test. Both patients recovered after local and systemic antifungal therapy, without relapse or side effects. Skin lesions on the face, which do not respond to the existing treatment in children, should be checked for the possibility of tinea faciei through repeated fungal tests, and the beta-D-glucan assay can be a useful tool in diagnosing tinea faciei.
