[Familial neoplastic syndromes of the ovary. A family study].

The authors describe a case of Lynch II type familial ovarian cancer syndrome. The family was first observed following the almost contemporary manifestation of ovarian cancer in two sisters. A subsequent analysis of family history among first and second degree relatives showed the presence of ovarian cancer in two maternal aunts, carcinoma of the colon in the father and breast cancer in a sister of the patients. Surgical treatment was selected for ovarian cancer associate with polychemotherapy in both cases. The patients' only living sister underwent preventive ovariectomy at the end of her reproductive programme. The latter is still undergoing follow-up due to the risk of developing neoplasia starting from the peritoneum. The diagnosis of ovarian cancer should result in a careful analysis of the pedigree of the patient suffering from the disease in order to highlight cancer at an early stage in other members of the same family.
