A2 - Appachi, Elumalai PY - 2015 T2 - The Color Atlas of Pediatrics AB - A 3-month-old African American boy is brought to the clinic with white spots on his face for one month (Figure 135-1). The child is otherwise in great health, eating well and gaining weight. The mother was negative for HIV during pregnancy. On physical exam, there are hypopigmented patches on the face especially at the hair line and under the eyebrows. There is visible scale in each of these patches. The hypopigmentation occurs secondary to the toxic effect of the Malassezia (Pityrosporum) on the melanocytes (as seen in tinea versicolor). The diagnosis of seborrheic dermatitis is made and treatment is begun with appropriate topical agents to treat the inflammation and the Malassezia. The mother is told to shampoo the infant’s hair with a selenium-based shampoo every 1 to 2 days and to apply 1 percent hydrocortisone cream to the hypopigmented areas twice daily for the next 2 weeks. At a 2-week follow-up, the scale is gone and the hypopigmentation is resolving.
