Reactive lymphoid hyperplasia is a condition in which the lymph tissues of the body (lymph nodes and spleen, primarily) enlarge as they respond to a viral or bacterial infection. The reason they enlarge has to do with the way that lymph tissues work. The lymph tissues of the body (also known as the reticuloendothelial system) are one of our lines of defense against outside invasion. Blood passes through these tissues, where it is monitored by specialized cells that live in the lymph tissues. If these cells detect an invader, they activate. In this activation process, the cells enlist the help of the reticuloendothelial system, causing it to produce millions of cells just like itself - all of which are capable of either (a) producing antibodies directed against the invader or (b) attacking the invader directly and phagocytizing ("eating") it. This distinction depends mainly on the type of pathogen detected; some pathogens provoke an antibody response and some provoke a cell-mediated response. In the process of reacting to the invasion and subsequent alarm, and while ramping up production of these cells, the lymph tissues enlarge. They do this because they become engorged with the immature cells before those cells can be released to do their job out in the body, and also partially because of the increase in blood flow and increase in metabolic activity in these tissues. The term hyperplasia comes from the Greek root words hyper-, which means an increase, and plastein, a verb which means to form or make. The combination of the two creates a word whose meaning is basically "to make bigger".
A polymorphous population of lymphocytes is usually a good sign; More of a reactive process. A monomorphic population is suspicious for lymphoma. Hope this helps.
Not exactly, it precancerous condition is estimated to progress to cancer in about 1/3 of the cases
It's a cancer which can't be cured. Joking .. I don't know either
There are several diseases and disorders that present as nodular mucosa of the duodenal bulb. Some examples are, heterotopic gastric mucosa, benign lymphoid hyperplasia, Brunner gland hyperplasia, Cronkhite-Canada syndrome and Peutz-Jeghers syndrome.small nodularity in the bulb of duodenum
Lymphoid tissue is what makes lymphoid organs so to answer your question, yes.
lymphoid organ in the chest
no, thyroid is not a lymphoid tissue but a gland.
hyperplasia is severe medical condition. Your organs swell and increase in size.
Lymphoid tissue is found in many organs, particularly the lymph nodes, and in the lymphoid follicles associated with the digestive system such as the tonsils
