| Abstract |
Chronic Non-bacterial Osteomyelitis (CNO) is an autoinflammatory bone disorder that causes non-bacterial and non-neoplastic osteomyelitis. CNO appeared to the long bone, clavicle, pelvis, and spine on children commonly. This time, we report a case with osteomyelitis of the mandible for the adult-onset. A 25-year-old woman presented pustulosis palmaris/pustular psoriasis after the extraction of the lower right tooth 1 year before hospitalisation. She felt pain and swelling of the right jaw and an antibiotic, NSAIDs, and glucocorticoids were ineffective. The cortical osteotomy of right mandibular bone was carried out 2 months before hospitalisation, but the symptom was not improved and she was admitted to our hospital. For pustular psoriasis with CNO, we treated her with adalimumab and the pain and swelling in her right jaw disappeared immediately. One and two years after the treatment, osteolytic and sclerotic bone lesion and osteomyelitis were improved in both Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). An anti-TNF-α antibody may be an effective therapy for CNO resistant to conventional treatment.
