Auricular Perichondritis of an Unusual Etiology

Auricular perichondritis leading to perichondral abscess is an unusual complication of periauricular surgery. Early identification of the condition with aggressive and timely management is mandated to prevent permanent damage to the auricle. This article demonstrates the first reported case in literature of auricular perichondritis due to Neisseria flava. We discuss the presentation, diagnosis and management of auricular perichondritis in this patient and review mechanisms by which commensals acquire pathogenicity as seen in this report. An awareness of this unusual etiology and mechanisms of acquiring pathogenic nature by commensals will help guide clinicians in optimizing management of such conditions.
