Thalidomide may be an effective drug for Blau syndrome: a case report.

Blau syndrome (BS) is a monogenic autoinflammatory disease caused by mutations in nucleotide-binding oligomerization domain containing 2 (NOD2). BS is characterized by the clinical triad of granulomatous dermatitis, arthritis and recurrent uveitis. Due to the low incidence of BS and the lack of treatment studies with large samples, a specific treatment scheme has not been established.
