What does lymph node sinus histiocytosis mean?
Lymph nodes are small glands that function to filter the lymph (excess plasma that circulates around tissues in capillary beds); they are often the first place where infections and metastatic cancers are found. The sinuses of a lymph node are small open pockets between the lymphocytes where fluid can accumulate. Histiocytosis is an abnormal accumulation of histiocytes (also called macrophages). Therefore, lymph node sinus histiocytosis is an abnormal accumulation of macrophages within the open spaces of a lymph node. There are many potential causes of this, ranging from chronic infection to cancer. Your doctor will need to explain what the most likely cause is as well as treatment options and likely outcomes.

What are the roles of the thymus and the lymph nodes in immunity?
The thymus contains large numbers of T cells and scattered dendritic cells, epithelial cells and macrophages. Immature T cells migrate from red bone marrow to the thymus, where they multiple and begin to mature. Lymph nodes filter lymph, which enters a node through one of several afferent lymphatic vessels. As lymph flows through the node, foreign substances are trapped by reticular fibers within the spaces between cells. Macrophages destroy some foreign substances by phagocytosis and lymphocytes destroy other by a variety of immune responses. Plasma cells and T cells that have divided many times within a lymph node can also leave the node and circulate to other parts of the body.
What is reactive lymph node?
