THE COEXISTENCE OF A PRE-AURICULAR SINUS WITH POST-AURICULAR DERMOID CYST

A pre-auricular sinus will rarely present in coexistence with a post-auricular dermoid cyst. The coexistence of a discharging pre-auricular sinus with a post-auricular dermoid cyst presents a diagnostic challenge. Without meticulous history taking and physical exam, one would subject the patient to aggressive and unwarranted investigation and management modalities as though the infected post-auricular dermoid cyst were a mastoid abscess. We present a 15-year-old male who presented to the ENT clinic of Mulago National Referral Hospital and was diagnosed with an infected pre-auricular sinus with an infected post-auricular dermoid cyst.
