Abstract
We present the case of a 5-year-old boy with no personal or family history of bleeding disorders, who suffered from recurrent post-tonsillectomy bleeds. The patient required multiple separate emergency visits to theatre in the 2-week postoperative period to achieve haemostasis. Initial baseline coagulation tests were found to be normal. However more extensive clotting studies revealed that the patient had an undiagnosed 'mild' haemophilia A.
