: An Uncommon Pathogen in an Immunocompetent Adolescent with Chronic Osteomyelitis.

represents an uncommon pathogen in human infections. As a veterinary pathogen, causes canine ear and skin infections. Chronic osteomyelitis is a progressive process characterized by bone destruction and the formation of sequestrum. It may be a sequela of untreated or undertreated acute osteomyelitis or septic arthritis. Descriptions detailing the pathogenicity and virulence of osteomyelitis were limited to a few case reports. Among the three reported cases of osteomyelitis, immunosuppression, malignancy, and recent surgical procedures were comorbidities. Compared to those who are immunosuppressed, immunocompetent individuals are generally not susceptible to uncommon microorganisms. Early detection of osteomyelitis, aggressive appropriate prolonged antimicrobial treatment and a multidisciplinary approach contribute to optimal recovery. We report the first case of chronic osteomyelitis in an immunocompetent adolescent.
