The onset is sudden, with symptoms and signs depending on the platelet count. Bleeding is usually mild, unless the platelet count drops below 20,000/µL. With platelet counts from 20,000/µL to 50,000/µL, petechiae and ecchymoses are observed following mild trauma. With platelet counts less than 10,000/µL, generalized petechiae, ecchymoses, and mucosal bleeding occur. With platelet counts below 2000/µL, widespread ecchymoses, hemorrhagic bullae, and retinal hemorrhage occur.
