Massive Hemoptysis Due to the Rupture of Thoracic Aortic Aneurysm Caused by Leukemic Cell Infiltration in a Patient With Chronic Myelomonocytic Leukemia.

Massive Hemoptysis Due to the Rupture of Thoracic Aortic Aneurysm Caused by Leukemic Cell Infiltration in a Patient With Chronic Myelomonocytic Leukemia. J Clin Med Res. 2019 Feb;11(2):145-150 Authors: Tanaka H, Yano M, Kuwabara C, Kume A, Tamura Y, Murakami M, Shimizu R, Saito H, Suzuki Y Abstract Hemoptysis is occasionally experienced in patients with hematological malignancies who have respiratory tract infection and severe thrombocytopenia. Thrombocytopenia due to hematological disease is one cause of hemoptysis. Chronic myelomonocytic leukemia (CMML) is a clonal hematopoietic malignancy characterized by both a myeloproliferative neoplasm and a myelodysplastic syndrome. This malignancy often infiltrates various extramedullary organs and has a poor prognosis. An 84-year-old Japanese man with CMML was suffered from hemoptysis and dyspnea. When he arrived at the emergency room, hemoptysis stopped. His white blood cell count was 866 × 109/L with 3.5% blast cells and 36.5% monocytes; hemoglobin was 6.7 g/dL; platelets count was 19 × 109/L; and C-reactive protein was 16.23 mg/dL. Chest X-ray examination revealed an invasion shadow near the mediastinum in the left upper lung field. Chest computed tomography revealed a tumorous lesion in the left upper lobe, which had progressed to the mediastinum and formed an infiltration shadow around it. He was administered the antibiotics and the hemostatic agents under hospitalization. He also re...
