A 65-year-old woman was urgently admitted to our hospital for antibiotic-resistant fever, hypoxemia, and hyperleukocytosis and was diagnosed with acute monoblastic leukemia. Chest computed tomography revealed interlobular septal thickening, central ground-glass opacity, and a nodular shadow in the left lower lobe. Although several treatments for infectious disease and acute heart failure were administered, they were less effective. Transbronchial lung biopsy was performed on day 7 of hospitalization, and subsequently, pulmonary leukemic infiltration was confirmed. Based on the diagnosis, we decided to start intensive chemotherapy. Consequently, the abnormal lung shadow on computed tomography vanished, and complete hematological remission was achieved. Although acute myeloid leukemia is frequently associated with lung infiltration during onset, it is often difficult to distinguish it from other pulmonary complications. In clinical practice, intensive chemotherapy is often initiated based on the clinical evaluation without pathological confirmation of the lung disease. Our patient was accurately diagnosed based on the pulmonary leukemic infiltration observed pathologically and recovered well. Here we report our case along with a discussion of the relevant literature.

Runt-related transcription factor-1 (RUNX1), also known as acute myeloid leukaemia 1 protein (AML1), is a member of the core-binding factor family of transcription factors which modulate cell proliferation, differentiation, and survival in multiple systems. It is a master-regulator transcription factor, which has been implicated in diverse signalling pathways and cellular mechanisms during normal development and disease. RUNX1 is best characterized for its indispensable role for definitive haematopoiesis and its involvement in haematological malignancies. However, more recently RUNX1 has been identified as a key regulator of adverse cardiac remodelling following myocardial infarction. This review discusses the role RUNX1 plays in the heart and highlights its therapeutic potential as a target to limit the progression of adverse cardiac remodelling and heart failure.

Pleural effusion is a rare presentation of plasma cell myeloma, occurring in around 6% of patients during the course of their disease, most commonly as a consequence of a concurrent disease process like heart failure secondary to amyloid deposition. Direct infiltration of the pleural fluid by malignant cells leading to myelomatous pleural effusion is a rare mechanism occurring in less than 1% of patients with plasma cell myeloma, and it is associated with a worse prognosis. There are few case reports of myelomatous pleural effusion as an initial presentation of multiple myeloma. Pleural fluid infiltration by monoclonal plasma cells in the absence of an underlying plasma cell myeloma was not reported before in the literature. Tuberculosis is a known cause of polyclonal gammaglobulinemia, however few case reports described the coexistence of monoclonal gammopathy of undetermined significance and tuberculosis. Here we present an interesting case of pleural fluid infiltration by an abnormal looking clonal plasma cells associated with active pulmonary tuberculosis and parapneumonic effusion in a patient with a background of acute myeloid leukemia. Interestingly, the clonal plasma cell proliferation was confined to the pleural fluid without any evidence of an underlying plasma cell neoplasms (including monoclonal gammopathy of undetermined significance and plasmacytomas). Since our patient had an underlying meyloid neoplasm, we though about the possibility of secondary malignancy. However, in almost all patients with coexisting myeloid and plasma cell neoplasms, myeloid neoplasms developed following chemotherapeutic treatment of plasma cell neoplasms not the other way around. Given that, one must conclude localized extramedullary (pleural) plasma cell proliferation probably represents a transient reactive process to pulmonary tuberculosis which is an extremely rare phenomenon and not described before.

Drug repositioning is a strategy to identify new uses for approved or investigational drugs that are used off-label outside the scope of the original medical indication. In this review we report the most relevant studies about drug repositioning in hematology, reporting the signalling pathways and molecular targets of these drugs, and describing the biological mechanisms which are responsible for anticancer effects. Although the majority of studies on drug repositioning in hematology concern acute myeloid leukemia and multiple myeloma, numerous studies are present in the literature on the possibility to use these drugs also in other hematological diseases, such as acute lymphoblastic leukemia, chronic myeloid leukemia, and lymphomas. Numerous anti-infectious drugs, chemical entities used for the therapy of neurological or endocrine diseases, oral antidiabetics, statins, medications used to treat high blood pressure and heart failure, bisphosphonate, natural substance such as artemisin and curcumin, have found a place in hematological diseases treatment. Moreover, seve.
