Kimura disease is a rare disease with abundant eosinophils. It may show-up in a lymph node specimen. It is similar to angiolymphoid hyperplasia with eosinophilia.[1]

General

  • AKA eosinophilic lymphogranuloma, Kimura disease.
  • Chronic inflammatory disorder - suspected to be infectious.

Clinical:

  • Usually neck, periauricular.
  • Peripheral blood eosinophilia.
  • Increased blood IgE.

Epidemiology

  • Males > females.
  • Young.
  • Asian.

Microscopic

Features:[2]

  • Angiolymphoid proliferation.
    • Thick walled blood vessels with (plump) hobnail endothelial cells.[3]
  • Eosinophils - abundant - key feature.

DDx:

Notes:

  • In a lymph node... it may be signed-out as reactive lymphadenitis with follicular hyperplasia and prominent eosinophils, see comment.
  • Abundant eosinophils: consider Langerhans cell histiocytosis.

Images

IHC

  • Used to rule-out a clonal population, i.e. lymphoma.
