The name of the pathology can mean several options, for example: inflammation of the lymphoid tissue or lymph node, this name can also be considered as a result of the proliferation of lymphoid cells in other organs, or the proliferation of lymphoid tissue in the form of a node of various sizes, which impedes the movement of surrounding tissues and causes constant pain. Until now, the exact reasons for the formation of infiltrates have not been studied; there are suggestions about possible infections, general poisoning, injuries, joint diseases or problems with the health of the immune system. Regardless of the reasons, if infiltrated lymphoid is diagnosed, a medical examination and further treatment, which may be surgical, is required.
