Introduction. Pityriasis versicolor is a dermatomycosis caused by lipophilic yeasts that infect the superficial layers of the stratum corneum of the skin, more frequently in areas of higher humidity and temperature. The majority of cases occur in adolescents and adults. In comparison with the typical presentation in adolescents and adults, pityriasis versicolor in children has atypical features. Case report. We report two infants aged 40 and 50 days who presented with annular macules in the nape. The lesions were hypopigmented or faint pink, and with faint scaling. Microscopic examination of the scales was diagnostic for pityriasis versicolor. Discussion. The presence of Malasezzia sp as an opportunistic pathogen in the skin since the first days of life explains the possibility of an infection at young ages. The characteristics of this infection in young children are the facial and cervical localizations, with typical hypopigmentation with minimal desquamation, and tendency to confluence. Infants receiving parenteral nutrition may develop a septic syndrome related to central line infection originating in the skin colonization.
