Laparoscopic excision of a cystic retroperitoneal adenocarcinoma arising in a focus of extra-ovarian endometriosis

Abstract

We report an unusual case of a retroperitoneal cystic adenocarcinoma arising in a focus of extra-ovarian retroperitoneal endometriosis. The lesion was completely excised using a transperitoneal laparoscopic approach without the need for any adjuvant chemotherapy or radiation therapy. The patient remains clinically well with no evidence of recurrent or metastatic disease after 3 years of follow-up. To our knowledge, this is the first reported case of this type of rare extra-gonadal endometriosis-associated neoplasm with successful laparoscopic excision.Can Urol Assoc J 2010;4(3):E71-E73

Malignant transformation of superficial peritoneal endometriosis lesion

“…Recently, a laparoscopic excision of a cystic retroperitoneal adenocarcinoma arising in a focus of extraovarian endometriosis was described without the need for any adjuvant chemotherapy or radiation therapy. The patient remains with no evidence of recurrent or metastatic disease after 3 years of follow-up 13. In addition, a complex cyst in a postmenopausal woman with increased CA-125 must be removed with caution.…”
