LETTER TO THE EDITOR Reply: Rectal endometriosis and

prolactinoma We thank Dr Kurt and co-workers for providing a clinical example showing a possible link between hyperprolactinaemia and endometrio-sis, and the potential beneficial effect of dopamine agonists (DA) in the treatment of the disease. Several previous reports have focused on the association between hyperprolactinaemia and endometriosis (Gregoriou et al., 1999; Cunha-Filho et al., 2002). It has been postulated that the hyperprolactinaemic state could explain infertility related tomild andmoderate endometriosis, butperhaps thismisses themain point: hyperprolactinaemiamay increase angiogenesis and induce/maintain endometriotic lesions. Their letter describes a patient with rectosigmoid endometriosis and simultaneous galactorrhea and hyperprolactinaemia. She had recurrent rectal bleeding but, during the period of time that shewas underDA treatment, bleeding stopped and appeared again when the medication was discontinued.
