Background: Herniation of the appendix into a femoral hernia--also called De Garengeot hernia--is a rare but well-recognized entity. It is typically discovered incidentally during hernia repair. Acute appendicitis in a strangulated femoral hernia is even more uncommon.
Aim: Report a new case.
Case: We report on a patient admitted for a painful groin mass. She underwent emergency surgery. Exploration identified acute appendicitis in a strangulated femoral hernia sac.
Management: Appendectomy associated with Mac Vay's herniorrhaphy were performed. The outcome was uneventful.
Conclusion: Surgeons should be aware of the existence of this infrequent and atypical presentation of appendicitis and femoral hernia.
