If the lymph node or similar tissue is reactive, or otherwise benign, it should possess a mixture of kappa positive and lambda positive cells. If, however, one type of light chain is significantly more common than the other, the cells are likely all derived from a small clonal population, which may indicate a malignant condition, such as B-cell ...
Liver function tests (LFTs or LFs), also referred to as a hepatic panel or liver panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin , bilirubin (direct and indirect), and others.
In CLL, the lymphocytes are all genetically identical since they are derived from the same B cell lineage. CLL cells can express the typical B-cell markers such as CD19 and CD20, as well as abnormal surface markers such as CD5 and CD23. [32] On a peripheral blood smear, CLL cells resemble normal lymphocytes, although slightly smaller.
The histopathology of FLC is characterized by laminated fibrous layers, interspersed between the tumor cells. Cytologically, the tumor cells have a low nuclear to cytoplasmic ratio with abundant eosinophilic cytoplasm. [1] Tumors are non-encapsulated, but well circumscribed, when compared to conventional HCC (which typically has an invasive ...
Cancer can be seen as a disturbance in the homeostatic balance between cell growth and cell death. Over-expression of anti-apoptotic genes, and under-expression of pro-apoptotic genes, can result in the lack of cell death that is characteristic of cancer. An example can be seen in lymphomas. The over-expression of the anti-apoptotic Bcl-2 ...
Stauffer syndrome causes abnormal liver function tests, especially those that reflect the presence of cholestasis, i.e. abnormal bile flow. Hepatosplenomegaly may also be observed. The symptoms and signs resolve if the renal cell carcinoma (or another associated tumor) is successfully ablated. It is due to release of IL-6 from cancerous cell. [1]
These cells lack antigen specific B or T cell receptor because of the lack of recombination activating gene. [2] ILC2s produce type 2 cytokines (e.g. IL-4 , IL-5 , IL-9 , IL-13 ) and are involved in responses to helminths , allergens , [ 3 ] some viruses, such as influenza virus [ 4 ] and cancer.
Liver cytology specializes in the study of liver cells. The main liver cells are called hepatocytes; however, there are other cells that can be observed in a liver sample such as Kupffer cells (macrophages). [2] The liver is the biggest gland of the body. It has a wide variety of functions that range from the destruction of old blood cells to ...
