Abstract Chronic nonbacterial osteomyelitis (CNO) is a bone disease with nonbacteria osteitis of unknown etiology. Symptoms, including pain, swelling, fever, etc, always result in misdiagnosis and wrong therapy. This study aims to introduce the clinical features and the therapy of patients with CNO accompanied with mucocutaneous disease. The authors retrospectively reviewed the patients who presented to our hospital from 2000 to 2016, the final sample including 3 patients with CNO accompanied with mucocutaneous disease, who presented repeated severe pain of bone, swelling, tenderness, and fever during attack stage with no evidence of bacterial infections. One patient underwent surgery, and all of them took the therapy of nonsteroidal anti-inflammatory drugs and immunosuppressive agents. There was no significant effect after taken surgery, but good results with drugs. The study suggested us that medical therapy sometimes better than surgery in CNO accompanied with mucocutaneous disease.
