title: Preschool sarcoidosis manifesting as juvenile rheumatoid arthritis: a case report and a review of the literature of Japanese cases.
abstract: Nine Japanese cases of sarcoidosis in children of 4 years of age or younger have been reported in the literature, including the case presented here. Clinically, preschool sarcoidosis is distinctly different from that of older children; it is characterized by a triad of skin, joint and eye lesions without pulmonary involvement. It is easily confused with juvenile rheumatoid arthritis which also presents the symptoms of arthritis and uveitis. We report on a patient with preschool sarcoidosis who was initially diagnosed as having juvenile rheumatoid arthritis. We recommend prompt skin biopsy to differentiate between these conditions.
