title: [Sarcoidosis as an uncommon cause of articular pathology in pediatric patients].
abstract: We present two cases of sarcoidosis with chronic arthropathy presenting clinical and imaging findings compatible with chronic juvenile arthritis. One patient suffered from chronic nephropathy, with anomalous US pattern and sarcoid granulomas demonstrated at renal biopsy. Throughout the illness, the patient suffered from cutaneous lesions that proved to be sarcoid granulomas after biopsy. US and color-Doppler US were useful in detecting the lesions and in the follow-up of the chronic articular pathology in these children. Although sarcoidosis is uncommon, it is important to consider this disease in the diagnosis of chronic arthropathy in children. We analyze these two cases and comment on the clinical and imaging characteristics of pediatric articular sarcoidosis.
