A healthy adolescent girl presented with a prolonged dermatitis of both feet characterized by pruritus and accompanying desquamation (Figure 1). Physical examination revealed well-demarcated desquamative patches with scales on both distal feet, showing a sandal appearance. No local heat, swelling, or discharge from the skin lesions was noted. The patient’s medical history was otherwise unremarkable and she had no known history of atopic dermatitis. A fungal smear skin test with potassium hydroxide preparation was performed on the lesion, which showed negative findings.
