Microfilaria in lymph node mimicking Kimura disease

In tropical and subtropical countries, parasitic infections are very rampant causing peripheral blood and or tissue eosinophilia. Here, a case of microfilaria in lymph node that produced intense eosinophil infiltrate is being reported. The dense eosinophil collection in the lymph node raised a possibility of Kimura's disease because no worms were seen in the initial sectioning of the tissue. Extensive sampling and diligent search revealed sections of microfilaria embedded in the eosinophil abscess along with foreign body giant cell reaction to its sheath material, leading to the correct diagnosis of this case.
