This article deals with non-haematologic malignant, i.e. metastases, and non-malignant lymph node pathology. An introduction to the lymph node is in the lymph nodes article.

Haematologic malignancies (in lymph nodes) are dealt with in other articles - see haematopathology and lymphoma.

Overview

Clinical:

  • Lymphadenopathy.

Differential diagnosis:[1]

  • Infectious - fungal, mycobacterial, viral, protozoal (Toxoplasma), bacterial (Chlamydia, Rickettsia, Bartonella)).
  • Neoplastic - lymphoma, carcinoma.
  • Endocrine - hyperthyroidism.
  • Trauma.
  • Autoimmune - SLE, RA, dermatomyositis.
  • Inflammatory - drugs (phenytoin).
  • Idiopathic - sarcoidosis.

Follicle location cortex cortex and medulla
Germinal center edge sharp/well-demarcated poorly demarcated
Germinal center density well spaced, sinuses open crowded, sinuses effaced/
compressed to nothingness
Tingible body
macrophages 		common uncommon

light/dark pattern 		normal abnormal

Lymph node metastasis

General

  • Determination of lymph node status is one of the most common indications for the examination of lymph nodes.
  • It is a good idea to look at the tumour (if available) ...before looking at the LNs for mets.
  • Lymph node metastasis, in the absence of other metastases, often up-stage a cancer from stage II to stage III.

Gross

  • Outside:
    • "Large" - size varies by site.
      • Neck >10 mm.[3]
    • Shape - round more suspicious than oval.
  • Sectioned:
    • White firm lesion with irregular border - classic appearance.
    • Non-fatty hilum.[3]

Microscopic

Features:

  • Foreign cell population - key feature.
    • Classic location: subcapsular sinuses.
  • +/-Cells with cytologic features of malignancy.
    • Nuclear pleomorphism (variation in size, shape and staining).
    • Nuclear atypia:
      • Nuclear enlargement.
      • Irregular nuclear membrane.
      • Irregular chromatin pattern, esp. asymmetry.
      • Large or irregular nucleolus.
    • Abundant mitotic figures.
  • +/-Cells in architectural arrangements seen in malignancy; highly variable - dependent on tumour type and differentiation.
    • +/-Gland formation.
    • +/-Single cells.
    • +/-Small clusters of cells.

Notes:

  1. Cytologic features of malignancy may not be present; some tumours, e.g. gallbladder carcinoma, do not always have overt cytologic features of malignancy.
    • The diagnosis is based on the fact that they are foreign to the lymph node and architecturally consistent with a well-differentiated malignancy.
  2. Lymph node metastases in sarcomas are uncommon; they are seen in <3% of cases.[4]
  3. Fatty lymph nodes (esp. fatty hilus[3]) are less likely to harbor metastases.[5]
