De Garengeot hernia: appendicitis within a femoral hernia.

Many surgeons are familiar with Amyand hernia, which is an inguinal hernia sac containing an appendix. However, few surgeons know of the contribution of Rene Jacques Croissant de Garengeot, an 18th century Parisian surgeon, to hernias. He is quoted in the literature as the first to describe the appendix in a femoral hernia sac. We discuss the case of an 81-year-old woman who presented with appendicitis within a femoral hernia, a rare finding at surgery that is almost never diagnosed preoperatively. We also propose crediting Croissant de Garengeot by naming this condition after him. Although his full last name is Croissant de Garengeot, for convenience we suggest the simple diagnosis of "de Garengeot hernia."
