Kimura disease is a rare disease with abundant eosinophils. It may show-up in a lymph node specimen.
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:[1]
- Angiolymphoid proliferation.
- Thick walled blood vessels with (plump) hobnail endothelial cells.[2]
- Eosinophils - abundant - key feature.
DDx:
- Drug reaction.
- Parasitic infection.
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:
- Kimura disease - very high mag. (WC).
- Kimura disease - high mag. (WC).
- Kimura disease - intermed. mag. (WC).
IHC
- Used to rule-out a clonal population.
