Preauricular sinuses are common congenital malformations .They are usually asympto-matic but in some cases can get infected and present with intermittent discharge and ab-scess formation. We present a case of a 30yr old lady presenting with continuously dis-charging preauricular sinus which was not responding to antibiotic therapy. Surgical ex-cision in the presence of infection was consid-ered. This case report documents a rare presentation of a calculus in the Preauricular sinus tract as a predisposing factor for persis-tence of infection. The review of literature regarding Preauricular sinus and factors con-tributing to recurrence after surgery are also discussed in the article.
