Hand-Foot and Mouth Dısease and Reactıve Arthritis: An Unusual Paediatric Case.

Reactive arthritis is defined as arthritis that occurs during or after an extraarticular infection. It is mostly difficult to determine the causative agent that causes inflammation in the joints. Initially, salmonella, shigella, chlamydiaand yersinia were considered to be pathogenic agents. But recently, in addition to demonstrated viral and bacterial agents, there are also other cases of reactive arthritis after vaccinations with Rubella and Influenza. Herein a 3-year old boy is reported with reactive arthritis of left knee that developed shortly after hand-foot and mouth disease. This report represents the first detailed description of a paediatric case in literature with reactive arthritis following hand-foot and mouth disease.
