Latest revision as of 15:16, 16 February 2021

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.
