area, there are cells like tiny T lypmphocytes, eosinophils, plasmacytoid dendritic cells.
In the hyaline-vascular type, affected lymph nodes are characterised by follicular and interfollicular
Stages Female Male Gametogenesis Walls of the follicles Within the follicles are not juxtaposed with along the wall, it is intra- and possible to distinguish interfollicular
There was prominent interfollicular
vascular proliferation with a pronounced plasma cell infiltrate.
Antibodies to this protein stain the germinal center cells in lymphoid follicles, follicular cells, and interfollicular
cells in follicular lymphoma, large B-cell lymphomas, and Burkitt's lymphoma, and the majority of the Reed-Sternberg cells in nodular lymphocyte-predominant Hodgkin's disease.
During embryonic development, melanocyte precursors that arise from the neural crest populate several areas including the interfollicular
epidermis and hair follicle bulge in the skin; the uveal tract of the eye; and the stria vascularis, vestibular apparatus and endolymphatic sac of the ear.
Increased numbers of IgG4 plasma cells are present in the interfollicular
areas, the germinal centers, or in both locations.
Vitiligo is an acquired, progressive disorder that destroys melanocytes in the interfollicular
epidermis and occasionally in the hair follicles.
Ao The skin has three different populations of cellsAuhair follicles, moisturizing sebaceous glands, and the tissue in between, known as the interfollicular
areas were expanded by a dense eosinophilic cell infiltrate that formed abscesses in places (figure 1, B).

Morphological features of the follicles and the interfollicular
area in multicentric Castleman's disease (MCD) are highly variable.
