Bone metastases result in lesions or injury to the bone tissue. There are two types of lesions: lytic lesions, which destroy bone material; and blastic lesions, which fill the bone with extra cells.

Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are the same disease, but in CLL cancer cells are found mostly in the blood and bone marrow. In SLL cancer cells are found mostly in the lymph nodes. Chronic lymphocytic leukemia/small lymphocytic lymphoma is a type of non-Hodgkin lymphoma.

Low-grade chondrosarcomas often show endosteal scalloping and a small degree of osteolysis. Intermediate and high-grade lesions demonstrate more aggressive radiographic features, such as osteolysis, medullary expansion, cortical thickening, cortical disruption, and the presence of a soft-tissue mass.

In CLL, the abnormal cells develop from early blood cells called the lymphoid blood stem cells. The cancerous white blood cells are B lymphocytes, also called B cells. In CML, the abnormal leukaemia cells develop from early blood cells called the myeloid blood stem cells. They become myelocytes.

Lytic lesions of the skull include a wide range of diseases, ranging from benign conditions such as arachnoid granulations or vascular lacunae, to aggressive malignant lesions such as lymphomas or metastases.

Which of the following statements best describes the difference between virulent phages and temperate phages? Virulent phages can go through only the lytic cycle, whereas temperate phages can undergo either the lytic cycle or the lysogenic cycle.

These lesions may become eroded, crusted, ulcerated, or even occasionally infected. With light trauma, they can bleed easily. A pyogenic granuloma is shown in the image below.

Lymphocytes: If there is an elevation in the level of lymphocytes, the condition is known as lymphocytic leukocytosis. This may occur as a result of a virus or an infection, such as tuberculosis. It may also be linked to specific lymphomas and leukemias.

Item 117 Solution Lytic granules generally are released from CTLs when the T-cell receptors on these cells bind specifically to: A ) viral antigens presented on the surface of virus-infected cells. ... As the name implies, cytotoxic T cells kill cells that are infected with viruses or other pathogens.

Lytic lesions are areas where bone has been destroyed, leaving a hole in the bone. These lesions in the spine are common, and when severe, can lead to one or more vertebral compression fractures, which can be painful and even disabling.

A leukemoid reaction is a reactive neutrophilia that occurs in response to an infection, inflammatory process, or malignancy. Leukemia is mimicked by the extent of neutrophilia (usually < 35x109/L) and by the presence of circulating immature WBC'S. Most common differential point is leukemoid reaction vs.

In most cases, the infection is caused by the Staphylococcus bacteria. It is sometimes known as a hordeolum. Although uncomfortable and incredibly common, styes are not generally a cause for concern. Often the lump is red and painful and looks like a boil or pimple.

the difference between B-cell lymphocytes and T-cell lymphocytes is that B cells produce antibodies, and T cells destroy infected cells.

What is the difference between the shape of a bloodstain that impacts a surface at a low angle and one that impacts at a higher angle? the high angle the drop is smaller due to the spatter . Origin: where blood was projected form (shows position of the victim or suspect when the stain producing event took place.)

In mammals the blastula is referred to as a blastocyst. The blastocyst contains an embryoblast (or inner cell mass) that will eventually give rise to the definitive structures of the fetus, and the trophoblast, which goes on to form the extra-embryonic tissues.

Blastic plasmacytoid dendritic cell neoplasm, or BPDCN, is a rare, aggressive blood cancer, with features of both lymphoma and leukemia.
