Heart failure complicating with SAPHO syndrome.

A 65-year-old man was referred to our hospital with dyspnoea due to acute heart failure. He presented with swelling in the left clavicle and pustulosis on both soles. An antihypertensive drug and non-invasive positive pressure ventilation improved his condition rapidly. Since all his physical symptoms were compatible with the criteria of SAPHO (synovitis, acne, pustulosis, hyperostosis, osteomyelitis) syndrome, we suspected that the SAPHO syndrome might cause acute heart failure. The aetiology between SAPHO syndrome and heart failure is unclear. Further studies are needed to clarify their relationship.
