Abstract

Pityriasis versicolor is a mild chronic superficial fungal infection, usually involving the seborrheic area of the neck, upper arms, and back. In a few instances, however, the eruption has been confined to highly atypical areas, such as one palm, the soles, the face, the scalp, the penis, and the groin. Inverse pityriasis versicolor refer to clinical disease located predominantly in flexural areas. We report three cases of inverse pityriasis versicolor in a 55-year-old man, in a 47-year-old man, in a 27-year-old man. The lesion were manifested by slightly scaly, brownish macules on the groin. Potassium hydroxide (KOH) prepatation showed numerous short hyphae and spores, and Wood's lamp examination showed yellowish brown fluorescence of involved skins. Fungal culture on Leeming and Notman's media grew out the typical colonies of M. globosa and M. sympodialis after 2 weeks at 34 degrees C. The patients were treated with 200 mg of itraconazole daily for 1 week and topical antifungals.
