Fibromyalgia (fibrositis) in children.

The features of fibromyalgia (fibrositis) in children are similar to those in adults with the syndrome. Both juveniles and adults report diffuse musculoskeletal aches and/or stiffness with typical modulating factors. Moreover, they have no systemic manifestations, and routine laboratory studies yield normal results. On physical examination in both children and adults, multiple soft-tissue tender points are evident at characteristic, symmetric sites but with no evidence of arthritis.
