title: Expression of Rh0(D) antigen in choriocarcinoma of the uterus in an Rh0(D)-negative patient: report of a case.
abstract: Choriocarcinoma of the uterus developed in an Rh0(D)-negative woman six weeks after delivery of a normal Rh0(D)-positive child. Although the patient's medical history did not show any previous sensitization, a strong anti-Rh0(D) antibody was detected during evaluation preceding surgical removal of the tumor. The tumor was considered the most probable cause of the Rh0(D) sensitization, since large Rh0(D)-positive areas of tumor were demonstrated by the immunoperoxidase method. This finding indicates that the Rh0(D) antigen is not restricted to erythrocytes, as commonly assumed, but can also be expressed on other tissue, such as tumor tissue.
