Hastan?n y?zeyel Doppler Ultrason g?r?nt?lemesinde (USG), sol rektus abdominis kas? inferior d?zeyinde yumu?ak doku lezyonu izlendi. Bunun ?zerine klini?imizde ?ekilen abdominal MRG' de solda rektus kas? i?inde 4x3.5x1.5 cm boyutlu hipervask?ler kitle tespit edildi. Kitle eksizyonu uygulanan hastan?n patoloji raporu rektus kas? endometriyozisi olarak sonu?land?.

We present a case of endometriosis in rectus abdominis muscle that has been diagnosed in a 36 year old woman. The extrapelvic implantation of endometrial tissue has been described in virtually every organ. The abdominal wall is an uncommon site of extrapelvic endometriosis, where it usually develops in an old surgical scar. Endometriosis in the rectus abdominis muscle is rare. The patient was admitted at gynecological outpatient clinic with pain in left inguinal region and dysmenorhea. Superficial Doppler Ultrasonography (USG) revealed a soft tissue lesion in left rectus abdominis muscle. Abdominal magnetic resonance imaging was reported as 4x3.5x1.5 cm hypervascular mass. Excision of the mass in the rectus abdominis muscle was done and she had no intraoperative or postoperative complications. The pathologic report was endometriosis in rectus abdominis muscle. Histological examination revealed areas of typical endometrial glands surrounded by stroma and bordered by vessels with occasional foci of haemosiderinladen macrophages typical of endometriosis. Then she was discharged. Result: Endometriosis should be thought as differential diagnosis in reproductive age of women who have a mass on anterior abdominal wall, especially women with history of abdominal or pelvic surgery.
