Abnormal bleeding
Abnormal bleeding follows a pattern defined by the
underlying defect. Platelet abnormalities are associated
with spontaneous bleeding from the membranes of the
nose, mouth, and gastrointestinal and urogenital tracts.
Petechiae, purpuras, and ecchymoses are medical terms
denoting different sizes of hemorrhage into the skin.
In purpura there is an unexplainedand abnormal fragility
of the capillaries, resulting in pinpoint hemorrhages
in the skin and mucous membranes.
