Patient case (clinical description): A 23-year-old female has prolonged oral bleeding immediately after a tooth extraction.  Despite several interventions, the bleeding persists for hours and stops only after desmopressin (DDAVP) administration.  The patient has heavy menstrual cycles each month.  She has no other medical problems and takes no medications.  Her mother and grandmother have also had excessive bleeding during menstrual period.  Review of systems is positive for mild bruising on his legs. Laboratory findings reveal a normal platelet count and an abnormal ristocetin cofactor assay, as well as CB <= 0.30 IU/mL and FVIII:C <= 0.40 IU/mL.

Patient's own account: I'm a 23 woman and I went to the ER because of non-stop bleeding after my tooth extraction. I tried to make the bleeding stop but it just kept going for hours and it finally stopped when I took some medication called DDAVP. I usually have heavy periods, just like my mom and grandma had. I don't have any other medical condition and I don't take any other medication. The doctor noticed the bruises on my legs. I had to do some lab tests. I had a normal platelet count but an abnormal ristocetin cofactor assay. I had low CB and FVIII:C levels.
