11) Some reported cases were associated with hypersplenism, such as thrombocytopenia, anemia, and pancytopenia, or hematologic conditions, including malignancy.
Chronic anemia in thalassemic patients is managed with blood transfusion, iron chelation, and splenectomy in cases of hypersplenism.
Background: Littoral cell angiomas are distinctive splenic tumors that present with signs of hypersplenism and splenomegaly or may be discovered during evaluation for coexisting clinical conditions.
Patients with thrombocytopenia of multiple origin (decreased production and increased destruction, hypersplenism, or myelodysplastic syndromes), who presented with both decreased production rates and increased platelet destruction, were not included in this study (n = 25).

On the other hand, in patients with hypersplenism and autoimmune hemolysis the aim is to decrease the sequestration and destruction functions of the spleen while preserving its immune functions.
Abstract: Hypersplenism is a known complication of portal hypertension secondary to cirrhosis of the liver.
18) Patients with acquired cytopenia included the following: 2 with immune-mediated thrombocytopenia and 1 each with thrombotic thrombocytopenic purpura, systemic lupus erythematosus, orotic aciduria, osteomyelitis, chronic renal failure, inflammatory bowel disease, anemia of chronic disease, hypothyroidism, and liver disease with hypersplenism.
However, in hospitalized patients, quantitative differences in blood analytes may be accentuated, particularly when intravascular erythrocyte destruction is expected to occur, such as in bacterial or viral infections (5), hypersplenism, cardiac and hepatic abnormalities (6), exposure to venoms and toxins (6), and the use of oxidant drugs (7).
