Hookworm is one of the most common parasites in the world, but can be missed on stool examination. We report a 31-year-old man who was complaining of epigastric discomfort, with laboratory findings of iron-deficiency anemia and eosinophilia. He was found to be infected with hookworm (Ancylostoma duodenale), which was directly detected and retrieved from the duodenum with biopsy forceps during upper gastrointestinal endoscopy. We eliminated his infection successfully by the Damaso de Rivas-Kihara modified method and oral administration of pyrantel pamoate. This report indicates that it is important to check carefully even in the distal duodenum at routine upper gastrointestinal endoscopy whenever parasitic disease is suspected but is hard to diagnose because of a limited number of eggs in feces.
钩虫是世界上最常见的寄生虫之一，但粪便检查时可能会漏诊。我们报告一名31岁男性，他主诉上腹部不适，实验室检查发现缺铁性贫血和嗜酸性粒细胞增多。在上消化道内镜检查期间，通过活检钳直接从十二指肠中检测并取出钩虫（十二指肠钩口线虫），发现他感染了这种寄生虫。我们通过达马索·德·里瓦斯-木原改良法和口服噻嘧啶成功消除了他的感染。本报告表明，在怀疑寄生虫病但因粪便中虫卵数量有限而难以诊断时，即使在常规上消化道内镜检查时仔细检查十二指肠远端也很重要。
