title: Occult hemophilia: prolonged bleeding follows extraction.
abstract: A 51-year-old man had delayed and recurrent bleeding after tooth extractions. Occult hemophilia B was discovered. This case emphasizes the importance of evaluating patients for an underlying coagulopathy when bleeding greater than expected occurs. In this case, the patient had no personal or family history of bleeding.
