Abstract
Background
Thromboembolism with solid malignancies is a commonly associated feature, which is less common in hematological malignancies. Disseminated intravascular coagulation (DIC) causing thrombotic events is characteristically associated with certain hematological malignancies (e.g., acute promyelocytic leukemia (APL). Acute myeloid leukemia (AML) presenting as extensive thromboembolism is not a common clinical presentation. Anticoagulation in these subsets of patients remains a major challenge since patients often have thrombocytopenia and bleeding manifestations, requiring close monitoring.
Case Presentation
A 54-year-old male with a known case of ischemic heart disease on regular anti-platelet therapy presented with acute onset progressive shortness of breath with mild anemia. On further evaluation, the patient was diagnosed with bilateral pulmonary artery and venous thrombosis along with left complete renal and partial inferior vena cava (IVC) thrombosis. The patient was started safely on anticoagulant therapy with normal platelet counts. Later, peripheral smear and immunophenotyping by flow cytometry revealed the diagnosis of acute myeloid leukemia, and the patient started its treatment.
Conclusion
Extensive arterial and venous thrombosis at presentation of acute myeloid leukemia is an uncommon finding and needs anticoagulation therapy along with the treatment of the underlying disease. Close monitoring of bleeding and maintaining an adequate platelet count is required, especially in hematological malignancies.
