[Brenner tumor. Apropos of 3 recent cases]

In reference to three recent clinical cases, the authors review the literature regarding Brenner's tumors. It is a rare ovarian tumor (2 p. cent of ovarian tumors), often associated with other utero-adnexal pathological processes. Hormone secretions may be present in 50 p. cent of the cases. Malignant or "borderline" forms are rare. Its histogenesis is discussed.
