A case of De Garengeot's hernia with acute appendicitis and literature review.

Background: De Garengeot hernia is defined as femoral hernia containing appendix. An acute appendicitis in a femoral hernia is a extremely unusual surgical finding and occurs in 0.08%-0.013% of all cases.

Case Report: We report the case of an elderly woman, who presented with a typical clinical image of incarcerated femoral hernia and underwent open surgery. An infrainguinal incision was performed and after the dissection of hernia sac, an acute appendicitis within femoral hernia was revealed. Subsequently, appendectomy and hernioplasty were performed.

Conclusion: Acute appendicitis within femoral hernia should be included in differential diagnosis of patients presenting with clinical signs of an incarcerated femoral hernia and prompt surgical treatment is essential in order to avoid severe complications.
