title: A case of extragastrointestinal anisakiasis involving a mesocolic lymph node.
abstract: In a 43-year-old Korean man who underwent radical gastrectomy due to a malignant stromal tumor, was found to have an enlarged lymph node at transverse mesocolon. The lymph node exhibited histologically necrotizing eosinophilic granuloma formed around a track containing sections of a nematode larva. The well preserved nematode sections revealed polymyarian muscle cells, Y-shaped lateral cord, a large excretory gland cell, intestine and eosinophilic cuticle. The nematode sections were identified as a larva of Anisakis species. In Korea, this is the first case of extragastrointestinal anisakiasis.
