The distribution of intestinal capillariasis has been extended continuously through Asian countries. The first case in Korea was reported in 1993, and here we add 2 more cases. One case is a 41-year old man who was diagnosed by both eggs in the feces and worms in the biopsy specimen of the ileum. This case was supposedly infected in Indonesia. The other is a 78-year old man, who has not been abroad, and suffered from intractable diarrhea. He was diagnosed by eggs in the feces, and several juvenile worms were collected after anthelmintic treatment. In both cases the treatment was successful by albendazole.
