Leukemia patients may have a lot of red spots on their bodies, which are due to bleeding of the skin and mucous membranes caused by bone marrow infiltration that hinders normal hematopoiesis and a decrease in platelets. In addition, the use of chemotherapeutic drugs in the treatment of leukemia can also inhibit bone marrow function, causing a further decline in platelet levels, which can also exacerbate bleeding.
Leukemia patients due to leukemia cells proliferation, infiltration of bone marrow, inhibit the normal hematopoietic function, resulting in a decline in the number of platelets. Platelets are important blood cells for hemostasis, with adhesion, aggregation and contraction functions, which can form platelet thrombi to block damaged blood vessels and help initiate the coagulation process.
Thrombocytopenia caused by bone marrow infiltration in leukemia patients may lead to bleeding of skin and mucous membranes, red and purplish-red hemorrhages all over the body, and in severe cases, it may lead to internal bleeding and even fatal intracranial hemorrhage.
If severe thrombocytopenia is found, attention should be paid to strict bed rest to prevent injury and bleeding, and blood transfusion should be given to support treatment when necessary.
