Surgery, open or laparoscopic, is the only definitive treatment. We present a case of a 71-year-old woman with GH (initially misdiagnosed as a lipoma), its approach, and treatment. We performed a hernioplasty with two meshes (preperitoneal and subaponeurotic position) by an open approach: Sandwich technique. This technique is safe, feasible, and associated with no short-term complications or relapses.engHernia AbdominalHernia, AbdominalGrynfeltt Hernia (GH): A Rare Case of Herniajournal article10.7759/cureus.42478
