Unusual presentation of De Garengeot hernia.

De Garengeot hernia describes a rare phenomenon in which a vermiform appendix is found in a femoral hernia sac. We describe a case of De Garengeot hernia presenting as a groin lump associated with loss of appetite, weight loss and fatigue. A 72-year-old woman was referred to our rapid access 2-week clinic as isolated lymphadenopathy with a 4-week history of a gradual right groin swelling accompanied by an unintentional weight loss, lethargy and anorexia. An urgent excisional lymph node biopsy was performed preceding the CT scan of the chest, abdomen and pelvis. The biopsy showed a shaving of appendix wall, and the CT scan revealed a right-sided femoral hernia with appendix as its content. The patient was urgently contacted for a laparoscopic appendicectomy and an open right femoral hernia repair. The patient recovered well postoperatively, and her systemic symptoms fully resolved when reviewed 10 weeks after the operation. © BMJ Publishing Group Limited 2019. No commercial re-use.
