Localized Langerhans cell histiocytosis (LLCH), also known as eosinophilic granuloma, represents 50 to 60% of all cases of Langerhans cell histiocytosis. The standard treatment for LLCH has been lesion curettage or resection. Cases treated with intralesional corticosteroid injections combined with curettage have been described.We report the case of a three-year-old patient diagnosed of LLCH with extensive zygomatic bone involvement, who was treated with corticosteroid infiltrations and subsequent curettage of the lesion. One year after treatment, the patient is asymptomatic with zygomatic reossification evidenced on computed tomography. © 2010 SECOM.
