Purpura

Purpura refers to hemorrhagic skin/mucosal spots 3 mm-1 cm in diameter that do not blanch on pressure. It is divided into thrombocytopenic purpura (low platelets) and non-thrombocytopenic/vascular purpura (normal platelets, vascular fragility).

Causes and Pathogenesis

Causes: (1) thrombocytopenia/function defect; (2) vascular fragility (allergic/senile/toxic); (3) coagulation-factor deficiency; (4) mechanical/stasis.

Treatment

Treat underlying cause; platelet transfusion if low; corticosteroids for immune causes

Preventive Measures

Early diagnosis; treat underlying disease; avoid trauma/aspirin.
