Sarcoidosis in young children.

Sarcoidosis in children less than 6 years of age is a rare occurrence. Affected patients, however, have a characteristic triad of involved organs-skin, joints, and eyes. Cutaneous changes usually take the form of asymptomatic eczematous or infiltrated plaques and papules. Swollen synovium produces articular changes which are much more visible than symptomatic-pain is minimal and range of motion is usually not substantially impaired. Involvement of the eye may produce much more severe and permanent damage, however. Chest and joint x-rays are usually normal.
