Three Cases of Pityriasis Versicolor in Infancy / 대한피부과학회지

ABSTRACT

Pityriasis versicolor is a benign chronic superficial fungal disease of young adults, but it is rarely observed in infancy. We report three cases of pityriasis versicolor in infancy in a 5-month-old boy, a 4.5-month-old boy, and a 7.5-month-old girl. The lesions were manifested by slightly scaly, hypopigmented macules on the face and scalp. Potassium hydroxide(KOH) preparation 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. sympodialis and M. globosa after 2 weeks. The isolates grew well at 34degreeC. The patients were treated topically with ketoconazole twice a day for 4 weeks.
