1. Histology:
- the normal pattern of the lymph node structure is lost due to the presence of multiple merging foci and foci of necrosis caused by mycobacterium tuberculosis and occupying a significant area;
- necrosis foci are represented by structureless detritus in the form of an eosinophilic homogeneous mass; small layers of the remaining lymphoid node tissue are visible between the necrosis foci;
- clusters of large epithelioid cells and giant Pirogov-Lankhgans cells are clearly visible on the periphery of the necrosis foci; the node capsule and fatty tissue are unchanged.
2. Anatomy:
the lymph node is of a dense consistency, enlarged in size, and on the incision it is represented by crumbling masses of yellow-gray color, with a cheesy appearance.
