lymph node necrosis

lymph node necrosis

A nonspecific finding consisting of necrosis within nodal tissue, which can be divided into:
(1) Focal necrosis—usually benign, and seen in infection by bacteria, cat-scratch disease, EBV, fungemia, LGV, toxoplasmosis, tuberculosis, tularemia, trauma, vascular compromise, post-vaccination lymphadenitis or autoimmunity (e.g., SLE), mucocutaneous lymph node syndrome or Kawasaki’s disease, necrotising lymphadenitis or Kikuchi’s disease; and
(2) Global necrosis, 80% of which is associated with lymphoma.

A neoplastic cause is excluded by the lack of mediastinal or apical lung lesions on the CT scan, the presence of central lymph node necrosis, and the good response to TB treatment.
The histologic differential diagnosis for Kikuchi-Fujimoto disease includes systemic lupus erythematosus (SLE) and malignant lymphoma, which both exhibit lymph node necrosis and karyorrhexis.
