Abstract

Abstract : A 6-month-old girl was referred by an ophthalmologist because of postoperative bleeding. She was scheduled for operation because of persistent hyperplastic primary vitreous. Workups were done and prolonged partial thromboplastin time with normal platelet count, normal bleeding time, and prothrombin time were detected. There was negative family history of bleeding tendency in both maternal and paternal family, so at the first step, Factor XI assay was requested which was normal. Then, von Willebrand factor and factor VIII were assayed which was 127% and less than 1%, respectively. Severe factor VIII deficiency was not suspected in a girl unless in siblings of a hemophilic patient who gets married with her carrier cousin. Chromosomal study and genetic testing were requested and mosaic Turner syndrome (45 XO) with ring X (p22, 2q13) along with inversion 22 (hemizygote) was detected. Abdominal and pelvic sonography showed absence of both ovaries with presence of infantile uterus. Maternal genetic study was in favor of carrier of hemophilia (heterozygote inversion 22). To the best of our knowledge, this is the first case of association of Turner syndrome with severe hemophilia A and persistent hyperplastic primary vitreous.
