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".

What is the treatment for reactive lymphoid hyperplasia?
Treatment for reactive lymphoid hyperplasia depends on the symptoms and size of the lesions. In some cases, observation may be sufficient, while in other cases surgical excision or corticosteroid therapy may be required. Your healthcare provider will determine the best course of treatment based on individual circumstances.
What is polymorphous population of lymphocytes consistent with reactive lymphoid hyperplasia?
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.
What is a benign lymphoid?
A benign lymphoid refers to a noncancerous growth or condition involving lymphoid tissue, which is a part of the immune system that helps the body fight infections. Benign lymphoid conditions can include lymphadenopathy (enlarged lymph nodes), tonsillitis, and reactive lymphoid hyperplasia. These conditions are typically not life-threatening and do not spread like malignant lymphoid conditions, such as lymphoma.
What is lymphoid hyperplasia in the nasopharynx?
Lymphoid hyperplasia in the nasopharynx refers to an increase in the size or number of lymphoid tissues in that region. It can be a benign response to various infections or inflammations. However, in some cases, it may be associated with conditions like nasopharyngeal cancer.
Is lymphoid hyperplasia a cancer?
Not exactly, it precancerous condition is estimated to progress to cancer in about 1/3 of the cases
What is the difference between pseudoepitheliomatous hyperplasia and epithelial hyperplasia?
Pseudoepitheliomatous hyperplasia is a reactive proliferation of epithelial cells that resembles squamous cell carcinoma but lacks malignant characteristics, while epithelial hyperplasia refers to an increase in the number of epithelial cells in response to stimuli like inflammation or repair processes. Pseudoepitheliomatous hyperplasia can mimic malignancy clinically and histologically, whereas epithelial hyperplasia is a non-neoplastic proliferative process.
What is non-specific reactive hyperplasia?
Non-specific reactive hyperplasia is a non-neoplastic condition where there is an increase in the number of cells in an organ or tissue in response to a stimulus. It is a benign process that can occur in various tissues as part of an immune response or reaction to injury or inflammation. It is often reversible once the underlying cause is resolved.
Are lymphoid organs larger than lymphoid tissue?
Yes, lymphoid organs are larger and more complex structures that contain lymphoid tissue. Lymphoid tissue, on the other hand, refers to collections of immune cells found throughout the body, including in lymphoid organs such as the spleen, thymus, and lymph nodes.
Do lymphoid mass make lymphoid tissue?
Tonsil
Can you give me a sentence using the word hyperplasia?
hyperplasia is severe medical condition. Your organs swell and increase in size.
What is abnormal thickened soft tissues in the posterior nasopharynx?
Abnormal thickening of soft tissues in the posterior nasopharynx may indicate conditions such as lymphoid hyperplasia, adenoid hypertrophy, or a nasopharyngeal tumor. Further evaluation by an otolaryngologist may be necessary to determine the exact cause and appropriate treatment.
What is pseudo epitheliomatous hyperplasia?
oral lesion that may show pseudo epitheliomatous hyperplasia
