Interrelation of a lymph node with surrounding tissues
means a collocation of a node and surrounding tissues: absence of a link or
preserving of a capsule, presence of a connective tissue between a lymph node
and other structures; adhesion or contact with an organ (vessel, etc.) without
breaching of its integrity; involvement into tumorous process.
In elderly people a reduction and hardening of lymph
nodes is detected, some of nodes merge together (in elderly people large nodes
are usually found). At the same time there is a replacement of large areas by
fatty tissue. Fatty infiltration destroys a capsule of a node in senile age.
Lymph nodes with fat (often peripheral ones) look like roundish or oval
structures with moderately chromogenic heterogeneous (sometimes netlike) central
part and relatively thin hypochromogenic frame. A capsule of a node may be seen
fragmentary.
