We describe the case of a 59 year old man with type 2 Diabetes Mellitus who presented to our hospital with right parotid abscess. The pus culture yielded S. enterica subsp. arizonae. Our patient was treated with intravenous Ceftriaxone 2 g/day addition to oral ciprofloxacin 1 g/day for twenty days and made a full recovery.
There are only few cases reported in which S. enterica subsp. arizonae causes infection in the head and neck. It is difficult to expose the likely route of transmission. S. enterica subsp. arizonae should be included in the differential diagnosis of head and neck abscesses in patients who are immunocompromised.
