Case Report on Endometriosis Associated Peritoneal Endometrioid Carcinoma

Endometriosis-associated neoplasms will develop in 0.7-2.5% of women with endometriosis. We present a rare case report of endometriosis associated endometroid carcinoma of peritoneum. We report a case of 43 years female with chief complaints of menorrhagia, dysmenorrhoea and dyspareunia. Her imaging revealed an endometriotic cyst of in left ovary along with iso to hyperechoic nodular area seen in right iliac fossa. Laparoscopic exploration validated it to be a case of grade IV endometriosis along with presence of peritoneal nodule of 5.5 × 4.5 cm in right iliac fossa. The peritoneal nodular lesion was removed with en bloc wide local excision with clinically disease-free margin. Histopathology report of peritoneal nodule shows endometrioid adenocarcinoma. Complete surgical staging for peritoneal cancer was performed and was not advised any adjuvant therapy. Patient is disease free since last 3 years.
