Abstract
We present the case of a 4-year-old boy with annular, pruritic macules on the face, not responsive to the application of topical immunosuppressive therapy for atopic dermatitis. Clinically, annular, pruritic macules with cracked surface and crusted, raised borders, slowly enlarging were observed on the boy's cheeks. Dermatoscopy evidenced centrifugal extension and border hyperactivity, represented by multiple peripheral pustules, mainly follicular. At last, microscopy of skin scrapings, showing fungal hyphae, permitted the diagnosis of tinea incognita. We highlight the need for always suspecting tinea incognita in pruritic, annular macules, not responsive to immunosuppressants.
