Reactive lymphoid hyperplasias, also known as reactive lymphoid proliferations, refer to an abnormal and excessive growth of lymphoid tissue in response to an immune system reaction or stimulus. It is a condition characterized by the enlargement of lymphoid organs or tissues, such as lymph nodes, tonsils, or spleen, due to the accumulation of lymphocytes.
In these cases, the immune system reacts to various triggers, including infections, autoimmune disorders, inflammatory conditions, or even certain medications. As a result, the body produces an increased number of lymphocytes, which are the white blood cells responsible for fighting infections and maintaining immune function.
Reactive lymphoid hyperplasias can present in different ways depending on the affected organ or system. Common symptoms may include swollen lymph nodes, sore throat, fever, fatigue, night sweats, weight loss, and enlarged spleen.
Diagnosis of reactive lymphoid hyperplasias usually involves a thorough medical history assessment, physical examination, and specific diagnostic tests like blood tests, imaging studies (ultrasound, CT, MRI), or even a biopsy in certain cases.
Although reactive lymphoid hyperplasias are typically benign and not a cause for significant concern, it is crucial to evaluate the underlying trigger or condition responsible for the abnormal tissue growth. Treatment options may involve managing the primary cause, such as treating an infection or controlling an autoimmune disorder. In some cases, if the hyperplasia causes significant discomfort, complications, or damages surrounding structures, surgical removal of the affected lymphoid tissue may be recommended.
