Postauricular pilonidal sinus: a case report with literature review

Abstract

Introduction: Pilonidal sinus disease (PSD) usually occurs in sacrococcygeal region, with the rare extracoccygeal pilonidal sinus form representing only 2.2% of all pilonidal sinuses. We report a rare postauricular pilonidal sinus with literature review.Methods: Case report.Results: A 25-year-old man, presented with a postauricular nodule with chronic discharge for last three months. On examination, there was a 1 x 1 centimeter firm, tender nodule at the left post auricular area. Under local anaesthesia, the nodule was excited in toto and the wound closed primarily. Histopathological examination confirmed the diagnosis of PSD.Conclusion: The post-auricular region is another rare area of atypical PSD occurring. It may present as a chronic nodule, and excision with primary closure under local anaesthesia may lead to uneventful recovery
