Disseminated Mycobacterium chelonae infection in a patient receiving an epidermal growth factor receptor inhibitor for advanced head and neck cancer

We report a case of disseminated cutaneous Mycobacterium chelonae infection in a patient with head and neck cancer on salvage chemotherapy, including the epidermal growth factor receptor inhibitor cetuximab. Mycobacterium chelonae should be considered in the differential diagnosis of cutaneous infections in cancer patients receiving epidermal growth factor receptor inhibitors.
