A 55 year old man presented with numerous round achromatic atrophic macules and patches varying in diameter from 0.5-1 cm on his both arms [Figure - 1]. The lesions first appeared 4 months earlier and gradually increased in number. The lesions later became atrophic. There was no history of using drugs and topical corticosteroids. The rest of his general examination was unremarkable. A potassium hydroxide preparation showed numerous pseudomycelial hyphae and yeast cells with typical ′spaghetti and meatballs′ appearance [Figure - 2].

Punch biopsies were done: One from the atrophic lesion [Figure - 3]a and the other from the normal skin. The biopsy specimen of the atrophic lesion revealed multiple short hyphae and spores in the cornified layer [Figure - 3]a whereas fungal elements were not observed from the normal tissue [Figure - 3]b. Retiform effacement, epidermal thinning, and mild periadnexal lymphocytic infiltration were present. Verhoeff′s elastic stain showed no alteration of elastic fibers in the dermis compared with that of normal tissue. The patient was treated with oral itraconazole (200 mg daily for 3 weeks) and showed improved atrophic lesions and mycological recovery.
