Blau syndrome (BS) is a rare systemic inflammatory disease characterized by early onset granulomatous arthritis uveitis and skin rash. BS now refers to both the familial and sporadic (formerly early-onset sarcoidosis) form of the same disease. The proposed term pediatric granulomatous arthritis is currently questioned since it fails to represent the systemic nature of the disease.
