[Pathognomonic presentation of Kingella kingae infection].

Kingella kingae is an important and probably under-recognized pathogen in children. It has a predilection for bones, joints and vascular endothelium, but can also cause bacteraemia alone. We present a case of Kingella kingae that manifested itself by presternal soft tissue infection, and suggest that infection of the lower sternum and the junction between the manubrium and the xyphoid process are typical, if not pathognomonic for the organism.
