Acquired thrombocytopenia

Acquired thrombocytopenia is a hematologic condition defined by an abnormally low circulating platelet count—typically below 150,000 per microliter—that develops postnatally rather than from an inherited genetic defect Clinically, affected individuals may remain asymptomatic or present with mucocutaneous bleeding, petechiae, ecchymoses, and an increased risk of severe hemorrhage depending on the degree of platelet reduction

Acquired thrombocytopenia is a hematologic condition defined by an abnormally low circulating platelet count—typically below 150,000 per microliter—that develops postnatally rather than from an inherited genetic defect Affecting both pediatric and adult populations, it arises through diverse pathophysiologic mechanisms, including impaired bone marrow megakaryopoiesis, accelerated peripheral destruction, abnormal consumption, or splenic sequestration Etiologies encompass immune-mediated destructi...
