Y. Sakurai et al., PRESCHOOL SARCOIDOSIS MIMICKING JUVENILE RHEUMATOID-ARTHRITIS - THE SIGNIFICANCE OF GALLIUM SCINTIGRAPHY AND SKIN BIOPSY IN THE DIFFERENTIAL-DIAGNOSIS, Acta Paediatrica Japonica Overseas Edition, 39(1), 1997, pp. 74-78
Preschool sarcoidosis occurring in children less than 6 years old is r
are and characterized by the triad of skin, joint and eye manifestatio
ns without any pulmonary lesion. Because of similar clinical manifesta
tions, the diagnosis of preschool sarcoidosis and juvenile rheumatoid
arthritis (JRA) is confusing. A girl with preschool sarcoidosis, initi
ally diagnosed and treated as having JRA, is reported here. Ophthalmol
ogic examinations revealed posterior involvement of the eye. A gallium
scintigram of the head showed panda appearance. Biopsy of the cutaneo
us lesion demonstrated non-caseating granuloma. Gallium scanning may b
e an important clue to correct diagnosis.
