title: Endometriosis-associated intestinal tumours: a consequence of long-term unopposed oestrogen?
abstract: A case of malignant transformation in an extra-ovarian site, 13 years after total abdominal hysterectomy and bilateral salpingo-oophorectomy, is discussed in a patient on long-term oestrogen implants, which highlights the potential risks surrounding the use of long-term oestrogen replacement therapy.
