A 33–year-old woman was visited at the dermatological clinic of Loghman-e-Hakim Hospital with multiple hypopigmented patches on her right arm, buttocks and flanks. Her lesions developed over the past year with no regression. Lesions were resistant to multiple antifungal therapies. Clinical examination revealed multiple circular or oval patches on the right arm, flank and sacral area. There was no erythema but fine scales were observed on the lesions (Figure1). No cutaneous sensory deficit was detected and no abnormality was found on physical examination. Also, there was no family history of similar problems. Abdominal ultrasonography and chest x-ray were normal. We performed biopsy from one of the lesions.
