Abstract

INTRODUCTION: This report describes a "parasitic" endometriotic cyst of the small bowel. CLINICAL PICTURE: A menopausal woman with a pelvic mass presenting years after commencing hormone therapy. TREATMENT: We performed laparoscopic excision of a cystic tumour attached to the small bowel with a solitary vascular pedicle. OUTCOME: Histology confirmed it to be an endometriotic cyst of ovarian origin, probably resulting from spillage during previous surgery and reactivation with hormone therapy. CONCLUSIONS: We discuss the possible aetiology of this unusual presentation of endometriosis and review the literature on parasitic gynaecological tumours.
