Abstract
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.

Figs. 1-4 Photographs of the biopsied mucosa of the terminal ileum in the Case I. HE stain. Fig. 1. Three sectioned worms are in the epithelial layer. The villi are severely atrophic, and the crypts are hypertropic. Original magnification, ×200. Fig. 2. The worm sections show stichocytes in the thin body wall. One section includes an egg. Original magnification, ×400. Fig. 3. Oblique sections show a chain of stichocytes. Original magnification, ×400. Fig. 4. An egg is found in the lamina propria surrounded by numerous inflammatory cells. Oirginal magnification, ×400.
