As widespread prophylaxis with anti-D Antibodies has dramatically diminished anti-D-associated hemolytic disease of the newborn (HDN), other antibodies-associated HDN has become relatively more significant. Two genes encode Rh proteins: the RhD gene coding for the D and the Rh CcEe gene coding for Cc Ee Antigens. D is a rare Rh phenotype in which RBCs lack Cc/Ee antigens while D antigen is strongly expressed. Anti R17 antibodies are important monomorphic antibodies acting against all previously mentioned antigens. It can pass through the placenta as a G immunoglobulin, leading to fetal or neonatal hemolysis. Here, we reported an immunized pregnant female with D- - phenotype and a history of intrauterine fetal death who had high titer of anti-Rh17 antibodies in her subsequent pregnancy. We would discuss our management strategy which led to good perinatal outcomes. To the best of our knowledge, this is the second case of HDN reported in English written literature in Iran.
