Branching Dilated Vessels: A Possible Trichoscopic Clue for Diagnosis of Erosive Pustular Dermatosis of the Scalp in Children

Introduction: Erosive pustular dermatosis of the scalp (EPDS) is an inflammatory scalp condition that usually affects the elderly, while only few cases have been reported in childhood. In children, it may mimic fungal or bacterial infections, especially kerion. Case Presentation: We describe the usefulness of trichoscopy as a supportive diagnostic tool in 2 cases of pediatric EPDS. Discussion: Clinical distinction between EPDS and different types of alopecia in children is difficult, with a significant likelihood of diagnostic errors and delay in therapy. Trichoscopy may provide a noninvasive option that can help avoid invasive diagnostic procedures in children.
