title: Endometrial carcinoma in one horn of a bicornuate uterus.
abstract: BACKGROUND
  Tamoxifen therapy is related to endometrial adenocarcinoma. Bicornuate uteri are more common than assumed. There are a few reports of endometrioid carcinoma arising in a bicornuate uterus, but none of these discuss a serous papillary component or an association with tamoxifen therapy.
  
  
  METHODS
  This is a case of a mixed endometrioid and serous papillary endometrial carcinoma arising in one horn of a bicornuate uterus. Multiple benign polyps were also present.
  
  
  CONCLUSIONS
  Adequate tissue sampling of both horns is critical to arriving at a timely and accurate diagnosis of malignancy in patients with a bicornuate uterus.
