We report a case of a 79-year-old woman with a previous history of polycythemia vera, glaucoma and hypertension. Her previous surgeries included a cholecystectomy with an incidental finding of a gallbladder carcinoma with following partial liver resection and a hysterectomy. The surgery department was consulted regarding this patient due to abdominal pain in her lower abdomen and tumor in her right groin. A CT scan of the abdomen was obtained that showed a hernia with the appendix vermiformis in the hernia sac. She was operated with a preperitoneal open approach and an inflamed appendix from a femoral hernia sac was removed and a herniorrhaphy with a mesh was performed. The patient was discharged the day after the surgery. Femoral hernia with the appendix in the hernia sac is a rare type of hernia first descriped by Rene-Jacques De Garengeot in 1731 and now bearing his name.
