Abstract
Strangulation of the vermiform appendix into the femoral hernia sac (de Garengeot hernia) is very rare. This article presents a case of a 63-year-old woman with this kind of hernia which contained a strangulated tumour of the appendix. The patient presented to the hospital with a 3-day-long history of a palpable lump in the right groin. She had no other significant complaints, but USG imaging showed suspicion of the strangulated femoral hernia containing a bowel. The patient was operated on. As the tumour was not suitable to remove via groin incision, laparotomy was performed, followed by a release of the appendix with the tumour and their resection together with a fragment of the caecum. The postoperative course was uneventful, and histological examination showed appendiceal mucinous neoplasm with high-grade dysplasia. After oncological consultation, the patient underwent prophylactic right hemicolectomy.
