Carcinosarcoma of the uterus in a woman with Down syndrome.

There are only a few reports of uterine cancers in women with Down syndrome, whose tumor profile is marked by a reduced risk for solid neoplasms. There are no reports of a uterine carcinosarcoma arising in a woman with Down syndrome. in our case, a delayed diagnosis of uterine carcinosarcoma was confirmed in a 38-year-old, nulliparous, single, obese woman with Down syndrome, who presented with irregular vaginal bleeding. Although uterine cancers are underrepresented in women with Down syndrome, uterine malignancy should be considered in the differential diagnosis of abnormal vaginal bleeding. A timely and complete gynecological examination will preclude a delay in diagnosis.
