what is purpura?
Question:
Answers:
Purpura is purplish discolorations in the skin produced by small bleeding vessels near the surface of the skin. Purpura may also occur in the mucous membranes (such as the lining of the mouth) and in the internal organs.
It is also known as blood spots or skin hemorrhages.
Common Causes:
Conditions that cause purpura are grouped into 2 categories: nonthrombocytopenic and thrombocytopenic. Some common purpuras include:
NONTHROMBOCYTOPENIC PURPURAS
Pressure changes associated with vaginal delivery of an infant
Vasculitis such as Henoch-Schonlein purpura (anaphylactoid purpura)
Congenital cytomegalovirus
Congenital rubella syndrome (changes in the baby that can occur when a pregnant woman has rubella)
Drug-induced platelet dysfunction (some drugs can affect the action of platelets)
Senile purpura (the blood vessels become more fragile as a person ages)
THROMBOCYTOPENIC PURPURAS
Idiopathic thrombocytopenic purpura (ITP)
Immune neonatal thrombocytopenia (a disorder that can occur in infants whose mothers have ITP)
Platelet consumption in hemangioma
Drug-induced thrombocytopenia (some drugs can prevent the formation of platelets)
Meningococcemia (an infection caused by meningococcus bacteria)

Purpura is a rash with small reddish-purple spots that do not blanch (or fade) with pressure. It is caused by small hemorrhages in the skin. There are several conditions that usually present with purpura: Henoch Schoenlein Purpura (a vasculitis seen mostly in children), Idiopathic Thrombocytopenic Purpura, and Thrombotic Thrombocytopenic Purpura.
