We present a case of haematemesis and malaena, severe enough to require blood transfusion, caused by leech infestation from the southern region of Saudi Arabia. The site was the posterior pharyngeal wall. The common mode of presentation in leech endoparasitism is by nasal infestation and recurrent unexplained epistaxis. Leech endoparasitism should be considered as a cause in unexplained haematemesis in areas where aquatic leeches are commonly found.
我们报告一例来自沙特阿拉伯南部地区的因水蛭寄生导致呕血和黑便的病例，严重到需要输血。寄生部位是咽后壁。水蛭体内寄生的常见表现方式是鼻腔寄生和反复不明原因鼻出血。在常见水生水蛭的地区，水蛭体内寄生应被视为不明原因呕血的一个病因。
