Reflex sympathetic dystrophy in children.

Reflex sympathetic dystrophy is a syndrome characterized by pain in one or more extremities, usually associated with vasomotor changes. Its occurrence in childhood has long been thought to be rare. We describe six cases of pediatric reflex sympathetic dystrophy and suggest that this syndrome could be underdiagnosed in children and adolescents. Psychologic problems frequently play a role in this disorder, which often can be treated conservatively. We also point out that the diagnosis is mainly clinical. An early diagnosis can avoid unnecessary tests and potentially can improve response to treatment, and prognosis.
