Blau syndrome is a rare autosomal dominant monogenic auto-inflammatory disorder characterized by triad of granulomatous polyarthritis, dermatitis, and uveitis. However, it may be difficult to recognize this syndrome in the absence of all three characteristic clinical manifestations. A 3-year-old girl presented with early onset symmetric polyarthritis and developed granulomatous uveitis at 13 years of age. However, Blau syndrome was suspected at 21 years of age when she was diagnosed to have disseminated granulomas in liver and kidneys. Diagnosis of Blau syndrome was confirmed by finding a mutation in NOD2 gene (p.Arg334Gln; FP2678). She was initiated on adalimumab therapy and she showed good response to this treatment. We did a literature search to find out all reported cases of Blau syndrome with disseminated granulomatous inflammation and all cases of Blau syndrome that were treated with adalimumab therapy. Seventeen patients with Blau syndrome have been reported to have granulomas at unusual locations (liver; kidneys; lungs; salivary glands; intestine; and lymph nodes). Adalimumab has been reported to be used in 33 patients with Blau syndrome. The indication to initiate adalimumab in large majority of these patients was persistence of uveitis. A possibility of Blau syndrome should be considered in all children presenting with early onset arthritis (especially with the presence of boggy swelling) and granulomatous uveitis. Granulomas in the liver and kidney are uncommon disease manifestations. Adalimumab may be an effective treatment for patients with Blau syndrome who are resistant to other forms of therapy.
