  • 1Department of Parasitology, College of Medicine, Yonsei University, Seoul, Korea.


An imported case of rectal hookworm infection was diagnosed by stool examination and recovery of adult worms from the rectal mucosa by sigmoidoscopy. The chief complaints of a patient were diarrhea, abdominal pain and weight loss for about 1 month after returning from his travel abroad to the Southeast Asia. Leukocytosis(16,750/microliters) and peripheral eosinophilia(33.7%) were noticed without anemia. Typical hookworm eggs were detected by stool examination, and 3 worms were collected by sigmoidoscopy from rectal mucosa of this patient. Those worms were confirmed as adult worms of Ancylostoma duodenale(male:1, female:2) based on their morphological characteristics. The symptoms were relieved after treatment with anthelmintics. This case was considered as one of the imported parasitic infections in Korea, and a rare case of hookworm infection on human rectal mucosa.
