Abstract

SAPHO syndrome is a rare entity that compromises the skeletal system (arthritis - osteitis) and is associated with various dermatological conditions such as palmoplantaris pustulosis (PPP) and acne. We present the case of a 39-year-old man with invalidating arthritis derived from a SAPHO syndrome and hypothyroidism (after radioiodine treatment for a Graves' disease). Due to the severity and refractoriness of his disease, we decided to use infliximab. He showed a prompt and prolonged response of his joint and cutaneous manifestations after three doses of a tumor necrosis factor alpha (TNF-α) blocker. Interestingly, he also decreased his levothyroxine requirements after TNF-α blockade therapy. © Clinical Rheumatology 2007.
