Alternative titles and symbols : Boeck sarcoid; SARCOIDOSIS;
Description : Sarcoidosis is a granulomatous disorder associated with an accumulation of CD4 T
cells and a Th1 immune response. In childhood, 2 distinct types of sarcoidosis have
been described (Shetty and Gedalia, 1998). Usually the disease is detected in older
children by chest radiography, and the clinical manifestations are characterized by
a classic triad of lung, lymph node, and eye involvement, similar to those in adults.
In contrast, early-onset sarcoidosis (EOS; 609464), which usually appears in those
younger than 4 years of age, is rare and has a distinct triad of skin, joint, and
eye disorders, without apparent pulmonary involvement. Compared with an asymptomatic
and sometimes naturally disappearing course of the disease in older children, EOS
is progressive and in many cases causes severe complications, such as blindness, joint
destruction, and visceral involvement.;
Inheritance : Autosomal dominant;
Molecular basis : Susceptibility conferred by mutation in the major histocompatibility complex, class
II, DR beta-1 gene (HLA-DR1B, 142857.0001);
Laboratory abnormalities : Elevated erythrocyte sedimentation rate (ESR); Positive Kveim-Siltzbach skin test; Hypercalciuria; Elevated serum angiotensin-converting enzyme (ACE); Mononuclear cell noncaseating granulomatous inflammation on biopsy (lung, skin, lip);
