Abstract
Abdominal wall endometriosis is a vvell-circumscribed mass composed of endometrial gland and stroma which may develop after a gynecologic surgery such as a cesarean section, at the scar of incisions. Since they usually appear as a mass at the inci-sion area which can be mistaken for incisional hernia, patients submit to general surgeons. Correct pre-operative diagnosis is difficult. İn the light of current literatüre, we would tike to discuss the diagnosis and treatment planning of abdominal wall endometriosis, which is a rare lesion, by means of a case treated in our clinic. A 36-years-oid female patient who underwent a cesarean section four years ago presented vvith ongoing abdominal pain and mass at the left lovver quadrant since last year. Superficial ultrasonography showed a 14 mm x 12 mm hypoechoic nodular lesion vvith calcifications. Approximately 1 cm dia-meter nodular soft tissue was detected at computerized tomography. Fine needle aspiration biopsy was not diagnostic so exci-sional surgery was planned. The lesion in the left rectus abdominis muscle which was 2 cm in diameter was excised vvith safe margins. Histopathological report was endometrioma. As a result, history of previous gynecologic surgery especially cesarean section and periodic pain during the menses in woman patients vvith abdominal pain and abdominal vvall mass should raise sus-picion of endometrioma.
