Lymphoid hyperplasia is the rapid proliferation of normal lymphocytic cells that resemble lymph tissue which may occur with bacterial or viral infections. [1] The growth is termed hyperplasia which may result in enlargement of various tissue including an organ, or cause a cutaneous lesion .
Follicular hyperplasia (FH) is a type of lymphoid hyperplasia and is classified as a lymphadenopathy, which means a disease of the lymph nodes. It is caused by a stimulation of the B cell compartment and by abnormal cell growth of secondary follicles .
Lymphocytosis is an increase in the number or proportion of lymphocytes in the blood.Absolute lymphocytosis is the condition where there is an increase in the lymphocyte count beyond the normal range while relative lymphocytosis refers to the condition where the proportion of lymphocytes relative to white blood cell count is above the normal range.
Cutaneous lymphoid hyperplasia refers to a groups of benign cutaneous disorders characterized by collections of lymphocytes, macrophages, and dendritic cells in the skin. [ 2 ] : 725 Conditions included in this groups are: [ 2 ] : 725
The definition of the condition includes the requirement that the duodenal histological appearances are otherwise unremarkable, specifically with normal villous architecture. [2] In coeliac disease (also known as gluten-sensitive enteropathy), duodenal lymphocytosis is found in untreated or partially treated cases. This is the least severe type ...
Lymphoproliferative disorders are a set of disorders characterized by the abnormal proliferation of lymphocytes into a monoclonal lymphocytosis. The two major types of lymphocytes are B cells and T cells, which are derived from pluripotent hematopoietic stem cells in the bone marrow.
The mantle zone (or just mantle) of a lymphatic nodule (or lymphatic follicle) is an outer ring of small lymphocytes surrounding a germinal center. [1] It is also known as the "corona". [2] It contains transient lymphocytes. [3] It is the location of the lymphoma in mantle cell lymphoma.
Macrophages that contain debris from ingested lymphocytes are characteristic of a reactive follicular center in benign reactive lymphadenitis. Other accompanying signs of a benign follicular hyperplasia are well developed germinal centers with dark and light zones, in addition to numerous mitotic figures.
