What do Reed-Sternberg cells do?
What do Reed-Sternberg cells do?
Reed-Sternberg cells, the neoplastic cells of Hodgkin’s disease, express all membrane molecules required to function as antigen-presenting cells (APCs), such as major histocompatibility complex (MHC) class II antigens and the recently characterized B7 proteins, which are of critical importance for APC to adequately …
What is the difference between Hodgkin and non-Hodgkin lymphoma?
The primary difference between these two categories of lymphatic cancer is the type of lymphocyte that is affected. Hodgkin lymphoma is marked by the presence of Reed-Sternberg cells, which a physician can identify using a microscope. In non-Hodgkin lymphoma, these cells are not present.
What is the distinguishing feature of Hodgkin disease noted on histologic exam?
According to the Rye classification, Hodgkin lymphoma is divided into the histopathologic types of (1) nodular sclerosing, (2) lymphocyte predominant, (3) mixed cellularity, and (4) lymphocyte depleted. A characteristic feature of all forms of Hodgkin lymphoma is the presence of Reed-Sternberg cells.
How is Hodgkin’s lymphoma classified?
The current WHO classification of Hodgkin’s lymphoma (HL) generally distinguishes the relatively rare variant (approximately 5% of all cases of HL) of nodular lymphocyte predominant type from a second group, which comprises classical HL and is separated into four subtypes: lymphocyte rich type, nodular sclerosis type.
What is a Reed-Sternberg?
(rēd′stûrn′bûrg′) A large, abnormal, binucleated or multinucleated B cell that is characteristic of Hodgkin lymphoma. [After Dorothy M. Reed (1874-1964), American pathologist, and Carl Sternberg (1872-1935), Austrian pathologist.]
How do Reed-Sternberg cells arise?
Reed–Sternberg Cells☆ They build together with the mononucleated Hodgkin cells the tumor cell clone in Hodgkin lymphoma and derive from Hodgkin cells through incomplete cytokinesis. Reed–Sternberg cells originate from mature B cells, or in very rare instances from T cells.
Is Hodgkins or non-Hodgkin’s more serious?
Hodgkin’s lymphoma is recognized as one of the most treatable cancers, with over 90% of patients surviving more than five years. Non-Hodgkin’s, however, often arises in various parts of the body.
What type of cell is characteristic of Hodgkin lymphoma?
Classic Hodgkin lymphoma (cHL) accounts for more than 9 in 10 cases of Hodgkin lymphoma in developed countries. The cancer cells in cHL are called Reed-Sternberg cells. These cells are usually an abnormal type of B lymphocyte.
What is the treatment for early stage lymphoma?
Radiotherapy is most often used to treat early-stage non-Hodgkin lymphoma, where the cancer is only in 1 part of the body. Treatment is normally given in short daily sessions, Monday to Friday, usually for no more than 3 weeks.

Why is it called Hodgkin’s lymphoma?
Hodgkin’s lymphoma is a cancer of the lymphatic system that affects the B-lymphocytes, causing them to accumulate in the lymph nodes. The cancer is named after Thomas Hodgkin who first described abnormalities in the lymphatic system in 1832.
