A rare case of Campylobacter rectus pyogenic extensor tenosynovitis

Pyogenic extensor tenosynovitis is a severe inflammatory process of the extensor compartment of the hand. Common pathogens involved in this condition are Streptococcus and Staphylococcus; however, in immunocompromised patients, rare pathogens can be implicated.

Herein a rare case of a 61-year-old female who developed severe extensor tenosynovitis from Campylobacter rectus after a dog bite is presented. The patient required surgical debridement, four weeks of doxycycline and amoxicillin-clavulanate antibiotic therapy and physical therapy to successfully cure her C. rectus infection and preserve functionality.

This case reinforces the virulence of microaerophilic pathogens, the need for multidisciplinary management in complex cases and alternative treatments with morbid obesity. As well, this case adds to the paucity of data with respect to this pathogen causing infections outside periodontal disease.
