An unexpected presentation of endometriosis--a "parasitic" cyst of the bowel in a menopausal woman on hormone therapy.
BACKGROUND
This report describes a "parasitic" endometriotic cyst of the small bowel.


METHODS
A menopausal woman with a pelvic mass presenting years after commencing hormone therapy.


METHODS
We performed laparoscopic excision of a cystic tumour attached to the small bowel with a solitary vascular pedicle.


RESULTS
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.
