A Case of Early Onset Sarcoidosis Masquerading as Juvenile Rheumatoid Arthritis / 대한피부과학회지

ABSTRACT

Sarcoidosis is a chronic multisystemic granulomatous disorder of unknown cause that occurs rarely in children. There are 2 types of sarcoidosis in children: early onset in children less than 4 years old and late onset in children 8 to 15 years old. The clinical manifestation of late onset sarcoidosis in children is similar to that of adults. Early onset sarcoidosis is difficult to diagnose however because its symptoms mimic those of juvenile rheumatoid arthritis (JRA). Early differentiation of sarcoidosis from JRA is important in planning treatment strategies and in counseling patients and families. Here we present a case of early onset sarcoidosis resembling JRA.
