|
Leukemia, Hairy Cell
|
D007943 |
[A neoplastic disease of the lymphoreticular cells which is considered to be a rare type of chronic leukemia; it is characterized by an insidious onset, splenomegaly, anemia, granulocytopenia, thrombocytopenia, little or no lymphadenopathy, and the presence of "hairy" or "flagellated" cells in the blood and bone marrow.
] |
|
Leukemia, Large Granular Lymphocytic
|
D054066 |
[A spectrum of disorders characterized by clonal expansions of the peripheral blood LYMPHOCYTE populations known as large granular lymphocytes which contain abundant cytoplasm and azurophilic granules. Subtypes develop from either CD3-negative NATURAL KILLER CELLS or CD3-positive T-CELLS. The clinical course of both subtypes can vary from spontaneous regression to progressive, malignant disease.
] |
|
Leukemia, Lymphocytic, Chronic, B-Cell
|
D015451 |
[A chronic leukemia characterized by abnormal B-lymphocytes and often generalized lymphadenopathy. In patients presenting predominately with blood and bone marrow involvement it is called chronic lymphocytic leukemia (CLL); in those predominately with enlarged lymph nodes it is called small lymphocytic lymphoma. These terms represent spectrums of the same disease.
] |
|
Leukemia, Lymphoid
|
D007945 |
[Leukemia associated with HYPERPLASIA of the lymphoid tissues and increased numbers of circulating malignant LYMPHOCYTES and lymphoblasts.
] |
|
Leukemia, Mast-Cell
|
D007946 |
[A form of systemic mastocytosis (MASTOCYTOSIS, SYSTEMIC) characterized by the presence of large numbers of tissue MAST CELLS in the peripheral blood without skin lesions. It is a high-grade LEUKEMIA disease with bone marrow smear of >20% MAST CELLS, multi-organ failure and a short survival.
] |
|
Leukemia, Megakaryoblastic, Acute
|
D007947 |
[An acute myeloid leukemia in which 20-30% of the bone marrow or peripheral blood cells are of megakaryocyte lineage. MYELOFIBROSIS or increased bone marrow RETICULIN is common.
] |
|
Leukemia, Monocytic, Acute
|
D007948 |
[An acute myeloid leukemia in which 80% or more of the leukemic cells are of monocytic lineage including monoblasts, promonocytes, and MONOCYTES.
] |
|
Leukemia, Myelogenous, Chronic, BCR-ABL Positive
|
D015464 |
[Clonal hematopoetic disorder caused by an acquired genetic defect in PLURIPOTENT STEM CELLS. It starts in MYELOID CELLS of the bone marrow, invades the blood and then other organs. The condition progresses from a stable, more indolent, chronic phase (LEUKEMIA, MYELOID, CHRONIC PHASE) lasting up to 7 years, to an advanced phase composed of an accelerated phase (LEUKEMIA, MYELOID, ACCELERATED PHASE) and BLAST CRISIS.
] |
|
Leukemia, Myeloid
|
D007951 |
[Form of leukemia characterized by an uncontrolled proliferation of the myeloid lineage and their precursors (MYELOID PROGENITOR CELLS) in the bone marrow and other sites.
] |
|
Leukemia, Myeloid, Accelerated Phase
|
D015465 |
[The phase of chronic myeloid leukemia following the chronic phase (LEUKEMIA, MYELOID, CHRONIC-PHASE), where there are increased systemic symptoms, worsening cytopenias, and refractory LEUKOCYTOSIS.
] |
|
Leukemia, Myeloid, Acute
|
D015470 |
[Clonal expansion of myeloid blasts in bone marrow, blood, and other tissue. Myeloid leukemias develop from changes in cells that normally produce NEUTROPHILS; BASOPHILS; EOSINOPHILS; and MONOCYTES.
] |
|
Leukemia, Myeloid, Chronic, Atypical, BCR-ABL Negative
|
D054438 |
[A myelodysplastic/myeloproliferative disorder characterized by myelodysplasia associated with bone marrow and peripheral blood patterns similar to CHRONIC MYELOID LEUKEMIA, but cytogenetically lacking a PHILADELPHIA CHROMOSOME or bcr/abl fusion gene (GENES, ABL).
] |
|
Leukemia, Myeloid, Chronic-Phase
|
D015466 |
[The initial phase of chronic myeloid leukemia consisting of an relatively indolent period lasting from 4 to 7 years. Patients range from asymptomatic to those exhibiting ANEMIA; SPLENOMEGALY; and increased cell turnover. There are 5% or fewer blast cells in the blood and bone marrow in this phase.
