Pustulotic arthro-osteitis (Sonozaki Syndrome): A rare case report.

Pustulotic arthro-osteitis is a rare disease involving the skin and musculoskeletal system that was first described by Sonozaki. Onset is frequently seen at age 30-40. The prevalences between the sexes are similar. Palmoplantar pustulosis and sternoclavicular joint involvement are the most typical findings. It may be difficult to distinguish seronegative spondyloarthropathies and SAPHO syndrome due to sacroiliac joint, vertebral column and peripheral joint involvement. Arthritis being non-erosive and short-lived in character and the absence of deformity or contracture in the joints are significant clinical characteristics. Anti-inflammatory and immunesuppressive drugs are used in the treatment of the disease, the course of which involves remission and flare-ups. We describe the case of a 43-year-old male patient diagnosed with pustulotic arthro-osteitis.
