title: 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.
