Femoral hernia accounts for only 3% of all the hernias and in only 0.5%-5% of the events, the appendix can travel through the femoral hernia which is called De Garengeot hernia, and the incidence of appendicitis in this type of hernia is as low as 0.08%-0.13%. We present a case of a 69-year-old healthy woman who was referred to the emergency department by her general practitioner for CT-proven appendicitis in the femoral canal. On initial assessment, she was found to have a hard, tender lump in her right groin below the inguinal ligament, and open appendectomy and herniorrhaphy were performed. Surgery is the mainstay of treatment of this type of hernia but due to the rarity of this condition, there is no specific guideline as for the surgical procedure. This article demonstrated a case of De Garengeot hernia which was diagnosed preoperatively and managed surgically.
