Primary myelofibrosis (PMF) is a rare bone marrow blood cancer. [1] It is classified by the World Health Organization (WHO) as a type of myeloproliferative neoplasm, a group of cancers in which there is activation and growth of mutated cells in the bone marrow. This is most often associated with a somatic mutation in the JAK2, CALR, or MPL genes.
Myeloma bone disease is due to the overexpression of receptor activator for nuclear factor κ B ligand by bone marrow stroma. RANKL activates osteoclasts , which resorb bone. The resultant bone lesions are lytic (cause breakdown) in nature, and are best seen in plain radiographs, which may show "punched-out" resorptive lesions (including the ...
Myeloproliferative neoplasms (MPNs) are a group of rare blood cancers in which excess red blood cells, white blood cells or platelets are produced in the bone marrow. Myelo refers to the bone marrow, proliferative describes the rapid growth of blood cells and neoplasm describes that growth as abnormal and uncontrolled.
Dysplasia can affect all three lineages seen in the bone marrow. The best way to diagnose dysplasia is by morphology and special stains used on the bone marrow aspirate and peripheral blood smear. Dysplasia in the myeloid series is defined by: Granulocytic series [citation needed]:
In hematology, essential thrombocythemia (ET) is a rare chronic blood cancer (myeloproliferative neoplasm) characterised by the overproduction of platelets (thrombocytes) by megakaryocytes in the bone marrow. [3] It may, albeit rarely, develop into acute myeloid leukemia or myelofibrosis. [3]
Multiple myeloma is a hematologic cancer, originating in the bone marrow, which also frequently presents as one or more bone lesions. [10] Germ cell tumors, including teratoma, often present and originate in the midline of the sacrum, coccyx, or both. These sacrococcygeal teratomas are often relatively amenable to treatment. [11]
Harvey Weinstein is battling cancer behind bars. Weinstein, 72, was diagnosed with chronic myeloid leukemia, a rare form of bone marrow cancer, NBC News reported on Monday, October 21. The ...
Chronic myelomonocytic leukemia (CMML) is a type of leukemia, which are cancers of the blood-forming cells of the bone marrow. In adults, blood cells are formed in the bone marrow, by a process that is known as haematopoiesis .
