SAPHO syndrome is a rare entity, composed of dermatologic and osteoarticular manifestations. There are no validated diagnostic criteria and treatment is empirical, with a recent focus on biologics. Herein, we present a 50-year-old woman who developed palmoplantar pustulosis and sternoclavicular osteitis, with typical findings on bone scintigraphy. Treatment with bisphosphonate, low-dose systemic corticosteroid, and cyclosporine allowed complete resolution of the articular and dermatologic manifestations with no side effects.
