        When there is a decrease in plasma
         levels or defect in the von Willebrand
         factor, the ability of the blood to clot
         decreases leading to a heavy and
         continuous bleeding after an injury.
               Clinical Manifesation
    Bleeding most often involves the mucous
     membranes.
    Nosebleeds, heavy menses, easy bruising,
     and prolonged bleeding from cuts and
     surgical sites are common.
    Soft tissue and joint hemorrhages are not
     seen often, unless the patient has type 3
     vWD.
    As laboratory values fluctuate, so does
     bleeding.

NHLS CAN BE CATEGORIZED AS:

remains localized or causes few symptoms
2. Aggressive fast-growing cancer that spreads
rapidly and causes significant morbidity
