Endometriosis is a common clinical problem in women of reproductive age. Endometriosis usually involves pelvis, peritoneum, ovaries, pouch of Douglas, and uterosacral ligaments, in addition to abdominal wall, albeit rarely. Meshes are frequently implanted today for the purpose of hernia repair. Synthetic mesh placement has been growing in number with an intent of improving success of certai n surgical procedures and prolonging treatment response. With increasing use of meshes, however, mesh-associated complications are coming to light. Such complications cover a broad spectrum including chronic erosion, dyspareunia, pain, infection, injury to rectum, bladder, and vessels. Here, we present a case who previously had undergone surgery due to umbilical hernia and was implanted with a mesh for whom total laparoscopic hysterectomy was indicated as she had uterine myoma and menometrorrhagia refractory to medical treatment. During her surgery, mesh in- fection was suspected upon which excision was performed and pathology report, in turn, revealed endometrioma.
