Case Reports

Corynebacterium xerosis (C. xerosis) is a component of normal skin flora, which rarely causes invasive infection. We report a case of left knee septic arthritis due to C. xerosis, review 2 previously reported cases of C. xerosis septic arthritis, and discuss the importance of the physician's role in interpreting the significance of skin flora recovered from cultures of an otherwise sterile site.
