Malassezia folliculitis in an infant.

Malassezia folliculitis commonly affects the adolescents and the young adults. We describe an unusual case of Malassezia folliculitis which is particular in age of patient and scare evolution of lesions. The patient was a three-month-old immuno-competent boy. On clinical examination, 1- to 2-mm superficial follicular pustules were observed on his face, neck and upper trunk. Direct microscopy of pustule scrapings and hair follicles showed numerous Malassezia yeast cells. Based on the clinical and mycological data, the diagnosis of Malassezia folliculitis was made. The possible predisposing factors in our patient were heat and sweating, caused by the excessive heat of the summer season in Tunisia. Treatment with topical ketoconazole promoted cure with depressed varioliform scars.
