How is follicular hyperplasia diagnosed and treated?
An official diagnosis of follicular hyperplasia might include imagining such as a PET scan and a tissue biopsy, depending on the clinical location and also the location of lymphadenopathy. A common blood panel test may help rule out other possible diagnosis, such as lymphomas based on the number of red, white and platelet cells found in the blood.

Radiation. It kills cancer cells.The radiation comes from a high-energy beam, similar to an X-ray, or from material put inside your body in or near the cancer. Follicular lymphoma responds well to radiation. In some cases, it can cure the cancer. If yours is at an early stage, you may only need radiation.
What is caused by follicular hyperplasia?
The term follicular hyperplasia refers to an increase in the number and size of follicles, which show variation in shape. Fusion of adjacent germinal centers may result in large, bizarre geographic structures.

What is atypical follicular hyperplasia?
Atypical follicular hyperplasia is a descriptive term that describes a diagnostic dilemma rather than a specific diagnosis. Table 1 lists the main histologic differential diagnostic features between reactive follicular hyperplasia and follicular lymphoma 6). Note that there is no one pathognomonic histologic feature. Therefore, one should rather rely upon a constellation of characteristics. Even the history can be helpful. The older the patient, the more likely the diagnosis is follicular lymphoma. Generalized lymphadenopathy is also more commonly seen with follicular lymphoma than reactive follicular hyperplasia. The one single most useful histologic feature is the density of follicles (follicle:interfollicular ratio) on low magnification. The more the follicles and the less the interfollicular areas, the more likely is the diagnosis of malignant lymphoma. In fact, a complete back-to-back arrangement of the follicles is seen in over 75% of cases of follicular lymphoma, while only seen in the most florid cases of reactive follicular hyperplasia. The greatest exception to this rule is when there are areas of diffuse nodal effacement, another feature favoring follicular lymphoma. These areas are usually focal, but are mass forming, and not distributed evenly around individual follicles. Lymph nodes with floridly reactive follicles may also occasionally show one or more of the following features: extension of the process outside the capsule, the presence of follicles throughout the node, predominance of centroblasts, and absent or greatly diminished mantle zones (Figure 1). These latter two features are particularly common in florid reactive follicular hyperplasia occurring in childhood as well as in cases associated with human immunodeficiency virus infection.
What are the features of a lymph node with follicles?

Is follicular hyperplasia a sinus hyperplasia?
Follicular hyperplasia is usually associated with varying degrees of paracortical and/or sinus hyperplasia. Reactive follicular hyperplasia is particularly commonly seen in children and young adults, but may be encountered in all ages, including the very elderly 3).

To date, the causes of hyperplasia of lymph nodes are considered as the reasons for their increase, which is the immune response to any pathological process that makes changes both in the dynamics of tissue metabolism of the lymph node, and in the ratio of certain cells.
What is reactive lymph node hyperplasia?
Experts emphasize that reactive lymph node hyperplasia is characterized by significant proliferative activity and, as a rule, affects the lymph nodes in the neck and lower jaw. From the point of view of cytomorphology, the reactive form has three types, the most common of which is the follicular form.
What is the term for the process of increasing the volume of tissue?
In fact, hyperplasia (Greek - over education) is a pathological process associated with an increase in the intensity of reproduction (proliferation) of tissue cells of any kind and localization. This process can begin anywhere, and its result is an increase in the volume of tissues.
Is lymph node hyperplasia a disease?
However, it should be noted that lymph node hyperplasia is not a disease, but a clinic al symptom.

And the lymph nodes are known to increase in response to any infection and inflammation.
Does lymph node hyperplasia cause proliferation?
And in the case of oncology, lymph node hyperplasia can involve any of their cells in the pathological process of proliferation. This causes an increase in the size, a change in the shape and structure of the fibrous capsule of the lymph node.

Follicles in such infections will appear much larger than those observed in viral conjunctivitis. Follicular conjunctivitis due to molluscum lesions. This type of eye condition appears in response to the molluscum contagiosum virus. This virus causes lesions to form on and around the eyelid margins.
Why are my follicles pale?
Follicles will turn pale on the surface and red at the base. This is due to an accumulation of lymphocytes (white blood cells in the immune system).

Overview
Treatment
Factors that identify etiology of the patient include age, duration of lymphadenopathy, external exposures, associated symptoms and location on the body.
Beta blockers such as Atenolol or ACE inhibitors like Captopril, can cause certain lymphadenopathies for some individuals. Captopril is an analog to proline and completely inhibits angiotensin converting enzymes (ACE) and as a result decreases angiostatin II production. It can also inhibit t…
Signs & Symptoms
Lymphadenopathies such as follicular hyperplasia can show various symptoms such as fever, chills, night sweats, unexplained weight loss and prominent localizing symptoms are non age and non-gender specific.
Although human lymph nodes cannot be seen with the naked eye, if you press against the skin you can sometimes feel for swelling and pressure. Swelling of lymph nodes can range from pea size…
Causes
The following are examples of potential causes for reactive lymphadenopathies, all of which have predominantly follicular patterns:
• Rheumatoid arthritis
• Sjögren syndrome
• IgG4-related disease (IgG4-related lymphadenopathy)
Mechanism
The specific pathology of follicular hyperplasia has not been fully understood yet. It is known, however, that a stimulation of the B cell compartment and by abnormal cell growth of secondary follicles are key factors to the pathology of follicular hyperplasia. This typically occurs in the cortex without disrupting the lymph node capsule. It has also been described that the condition may stem from primary reactive lymphoid proliferations that may be triggered by an unidentified antige…
Diagnosis
Follicular hyperplasia can be distinguished among other diseases by observing the density of a lymph follicle on low magnification. Lymph nodes with reactive follicles contain extensions outside its capsule, follicles present throughout the entire node, obvious centroblasts and the absence or diminishing mantle zones. Immunohistochemistry can help distinguish a difference between a patient with follicular lymphoma to follicular hyperplasia. Reactive follicular hyperplas…
Prognosis
Typically follicular hyperplasia is categorized as a benign lymphadenopathy. This is usually almost always treatable, but only until it progresses into malignancy. Therefore, follicular hyperplasia patients tend to live a long life until their condition is either treated or goes away on its own. Follicular hyperplasia becomes problematic when left untreated by increasing the risks for developing various types of cancers.
Epidemiology
Follicular hyperplasia is one of the most common types of benign lymphadenopathies. It can be typically found in children and young adults however all ages are subject to follicular hyperplasia, including the elderly. Lymphadenopathies such as follicular hyperplasia, are usually localized but can also be generalized and are non gender specific. Over 75% of all lymphadenopathies are observed as local, usually involving specifically the head and neck regions. It has been estimate…
