Eosinophilic fasciitis (EF) in childhood is a very rare, and it is characterized by diffuse fasciitis and peripheral eosinophilia. It has been reported that EF shows good recovery after systemic steroids. We report a case of 18 months old boy with eosinophilic fasciitis which affected the right lower extremity and flank. The case we present here differs from other published reports, in that the patient with eosinophilic fasciitis presented serious musculoskeletal complications such as muscle atrophy, osteoporosis, fracture, and inequality of limb length that were associated with chronic course of steroids therapy. Interdisciplinary approach is critical in preventing complications in children with eosinophilic fasciitis. (J Korean Acad Rehab Med 2009; 33: 493-497)
