Orbital and childhood sarcoidosis.
Orbital infiltration, anterior uveitis, disc edema, choroiditis, erythema nodosum, and polyarticular arthritis due to sarcoidosis occurred in a five-year-old child who presented with unilateral proptosis. Diagnosis was enhanced by computerized tomography of the orbit, and confirmed by synovial biopsy findings. This patient's course illustrates the importance of thorough and frequent ocular examinations in childhood uveitis associated with systemic disease and demonstrates an unusual finding of orbital sarcoidosis. Childhood sarcoid arthritis may be misdiagnosed as juvenile rheumatoid arthritis. Familiarity with the ocular and systemic findings may lead to the correct diagnosis.
