Abstract:
Atrophying pityriasis versicolor is a rare variant of pityriasis versicolor. Clinically, atrophying pityriasis versicolor is characterized by well defined, slightly scaly, depressed macules and patches with minimal symptoms. The etiology of the atrophy is unknown, though several hypotheses have been suggested, including immune reaction to antigens of Malassezia species. A 23-year-old male was presented with multiple, slightly brown colored macules and patches on the chest and back. In the potassium hydroxide preparation, lots of yeasts and hyphae were found. A histopathologic study showed multiple yeasts and hyphae on the stratum corneum, focal epidermal thinning, and perivascular lymphocytic infiltration on the upper dermis. The patient was treated with 100 mg itraconazole a day with topical antifungal agents. After 3 weeks of treatment, clinical improvement and mycological improvement were achieved. We present an additional case of atrophying piryriasis versicolor developed on the chest and back with the review of the relevant literature.
