In other areas of the lymph node scattered residual reactive follicles were present with preserved mantle zonesIn a few cases 4 of 32 the mantle was greatly attenuated and focally absent and the atypical cells in the marginal zone blended with the residual germinal centers imparting a vaguely nodular growth appearance on low power Fig.

The lymph nodes are organized lymphoid organs that contain lymphocytes within a fine reticular stromaThe structures within a lymph node include the capsule subcapsular sinus cortex B cell zone with follicles and germinal centers paracortex T cell zone medullary sinuses medullary cords and hilus.

Lymphocytes are highly controlled and not just a series of random stochastic events and how it occurs is now leading to a fundamental change in our understanding of the behaviour of the malignant counterparts of these cells10It is becoming clear that several shared ligands and their receptors are responsible for controlling the circulation and migration of lymphocytes particularly the integrms Table 4 and the selectins and some members of the immunoglobulin superfamily Table 5.

Lymphoid depletion or atrophy is the sequela to chronic necrosis or apoptosisIt can occur in any lymph node and there can be differences in the presence and severity of lymphoid depletion between lymph nodes in the same animalLymphoid depletion is typically characterized by a decrease in the number and size of follicles with few to no germinal centers andor depletion of paracortical lymphocytes Figure 1FWith a depletion of paracortical lymphocytes the stromal cells may become more prominent Figure 1G.

Mantle cell lymphoma MCL is a type of nonHodgkins lymphoma NHL comprising about 6 of NHL casesThere are only about 15000 patients presently in the United States with mantle cell lymphomaIt is named for the mantle zone of the lymph nodes.

Mantle zone definition of mantle zone by Medical dictionary.

Mantle cell lymphoma is a Bcell lymphoma that develops from malignant Blymphocytes within a region of the lymph node known as the mantle zoneAs previously mentioned the signs and symptoms of MCL are dependent on the extent of the region of the body that is affectedAlthough the exact underlying cause is unknown researchers have.

Mantle zone expansion may be seen in benign such as Castleman disease and malignancy iMCL is a subtype of Bcell lymphoma due to CD5 positive antigennaive pregerminal center Bcell within the mantle zone that surrounds normal germinal center follicles.

Mar 11 2021nbsp018332A lymph node contains a cortex a paracortex a medulla sinuses a hilum and a fibrous capsuleThe cortex is a Bcell area which contains primary nonstimulated lymphoid follicles composed of small mature lymphocytes and secondary activated follicles with germinal centers composed of a mixture of small cleaved lymphocytes centrocytes.

Synonymous names for this lesion are lymphangiectasia lymphatic cysts cystic lymphatic ectasia and sinus dilatationA group of pathologists that are associated with the National Toxicology Program were surveyed for the preferred terminology for this lesionThe 2 favored terms were x0201clymphatic sinus ectasiax0201d and x0201clymphangiectasiax0201d Lymphatic sinus ectasia more clearly defines the lesion location.

The mantle zone also contains some memory B cellsA secondary follicle is made up of a germinal center and surrounding mantle zoneSlide 5 In this lowpower image of a lymph node the hilar vessels are visible on the left side of the photographThe cortex is seen on the right side of the image and is composed of B cell follicles.

The mantle zone of the follicles contains resting and memory BcellsThe paracortex of the lymph node is a Tcell zoneOne feature of this region is the high endothelial venule where circulating lymphocytes leave the bloodstream to enter the nodeThese postcapillary HEVs can be distinguished by their cuboidal.
