Hematology
Idiopathic Thrombocytopenic Purpura
An autoimmune bleeding disorder where the immune system destroys its own blood platelets, causing easy bruising and bleeding.
Pernicious Anemia
An autoimmune disease causing lack of intrinsic factor, preventing Vitamin B12 absorption, and resulting in severe anemia and progressive nerve damage.
Iron Deficiency Anemia
A lack of iron leading to a reduced number of healthy red blood cells, causing fatigue and weakness.
Acute Myeloid Leukemia
An aggressive cancer of the myeloid blood cells where immature myeloblasts rapidly fill the bone marrow, causing severe anemia, infections, and bleeding.
Aplastic Anemia
A condition where the body's immune system destroys its own bone marrow, stopping the production of all blood cells and leading to severe fatigue, bleeding, and infections.
Chronic Myeloid Leukemia
A clonal bone marrow disease driven by the Philadelphia chromosome (BCR-ABL1), leading to massive overproduction of white blood cells and curable with targeted tyrosine kinase inhibitors.
Acute Lymphoblastic Leukemia
A rapid-onset blood cancer where immature white blood cells (lymphoblasts) multiply uncontrollably in the bone marrow, crowding out healthy cells.
Hemophilia
A genetic bleeding disorder where the blood doesn't clot properly due to missing clotting factors, leading to frequent bleeding into joints and muscles.
Polycythemia Vera
A slow-growing blood cancer causing the bone marrow to make too many red blood cells, making the blood dangerously thick and prone to clotting.
Sickle Cell Disease
An inherited genetic blood disorder where abnormal hemoglobin causes red blood cells to become sickle-shaped, leading to severe pain episodes, chronic anemia, and organ damage.
Chronic Lymphocytic Leukemia
An indolent clonal B-cell leukemia characterized by progressive accumulation of mature-appearing but dysfunctional lymphocytes, leading to lymphadenopathy and bone marrow failure.
