In adults, purpura is usually a sign of an underlying condition but can also resolve without treatment. Children typically recover quickly and without treatment. It’s slightly more common in adults than in children. Purpura larger than 1 centimeter (cm) is called ecchymoses (or bruises). If the purpura spot is less than 4 mm wide, it’s called petechiae. Purpura is between 4 millimeters (mm) and 10 mm in diameter. What is the difference between petechiae and purpura? This type of purpura happens when our blood vessels become weak. If you have senile purpura, you may have bruises or spots on the skin due to age or sun exposure. Disseminated intravascular coagulation (DIC): Your blood over clots because proteins that control blood clotting are overactive.

Warfarin-induced skin necrosis: Your skin’s tissue dies after a negative reaction to the drug warfarin.Heparin-induced thrombocytopenia: Occurs when a negative reaction to the drug heparin makes your body clot too much.Other serious (but rare) types of purpura require emergency medical treatment. The cause of purpura isn’t related to your platelet level. A person with nonthrombocytopenic purpura has platelet levels in a normal range.A person with thrombocytopenic purpura has low platelet counts.Platelets help your blood clot and prevent severe bleeding.
