EBV-positive reactive lymphoid hyperplasia (or EBV-positive reactive lymphoid proliferation) is a benign form of lymphadenopathy, i.e. swollen, often painful lymph nodes. The disorder is based on histologic findings that occur in the lymphoid tissue of mainly older individuals who were infected with EBV many years earlier.
Within the immune system, Follicular B cells (FO B cells) are a type of B cell that reside in primary and secondary lymphoid follicles (containing germinal centers) of secondary and tertiary lymphoid organs, including spleen and lymph nodes. Antibody responses against proteins are believed to involve follicular B cell pathways in secondary ...
Tonsillitis usually affects both tonsils, but can result in uvula swelling because of the infection and inflammation. “At times, one tonsil is infected and an abscess can occur that causes one ...
In situ lymphoid neoplasia (ISLN, also termed in situ lymphoma) is a precancerous condition newly classified by the World Health Organization in 2016. The Organization recognized two subtypes of ISLN: in situ follicular neoplasia (ISFN) and in situ mantle cell neoplasia (ISMCL). [1]
The palatine tonsils are located in the isthmus of the fauces, between the palatoglossal arch and the palatopharyngeal arch of the soft palate.. The palatine tonsil is one of the mucosa-associated lymphoid tissues (MALT), located at the entrance to the upper respiratory and gastrointestinal tracts to protect the body from the entry of exogenous material through mucosal sites.
