De Garengeot hernia masquerading as a painless groin lump: a case report

De Garengeot's hernia is a rare subtype of femoral hernia in which the appendix is located within the herniated sac. These cases are important to report as both the diagnosis and treatment are quite challenging. We present a case of a 68-year-old gentleman with few months history of a lump in the right groin that gave him mild discomfort but no other symptoms. Initial investigations with an ultrasound did not prove to be helpful and so a plan was made to surgically explore the lump. The appendiceal tip was incarcerated within the hernial sac. The appendix was removed using an open inguinal incision with repair of the defect using a light weight partially absorbable mesh. It is important to consider the possibility of a De Garangeot's Hernia as a differential diagnosis for patients presenting with a groin lump.
