A case of Human Anisakiasis in Korea

Abstract

A case of human anisakiasis involving terminal ileum was reported. The lesion was incidentally found in a 23~year old Korean male during an operation for duodenal ulcer perforation. As far as one could detect no symptoms directly referable to the lesion were present. Histopathologically, the lesion was characterized by transmural necrotizing and granulomatous inflammation with central cavitations. One section disclosed a sectioned anisakid larval worm, which was measured 208 X 118pm in diameters and was characterized by thick cuticle, thin hypodermis with Y-shaped lateral chords, large oesophagus, and polymyarian, coelomyarian musculature. The present case is the second human anisakiasis reported in Korea.
