血吸虫病是一种广泛流行的寄生虫(蠕虫)感染性疾病,罹患者约占全世界人口的5%。血吸虫病在许多发展中国家尚是一较重要的卫生问题。血吸虫有曼氏裂体血吸虫、日本血吸虫和埃及血吸虫三种,前两者主要感染损害消化系和肝脏,后者主要侵犯泌尿系。其虫卵几乎在身体各器官内都有小量沉积,但因缺乏症状而可能被忽视。Lima曾报道对544例血吸虫病尸检结果,其中96例(17.6%)有“异位病损”。一般临床不常见的病损部位为神经系统、眼附属器或皮肤。广泛复习文献耳鼻喉科的血吸虫病罕见,仅有4例报道,2例位于咽后壁,1例在增殖体,1例在喉部。但据一次对埃及100例晚期血吸虫病的 Schistosomiasis is a widespread epidemic of parasitic (helminth) infectious diseases that affects about 5% of the world’s population. Schistosomiasis is still a more important health problem in many developing countries.

Its eggs accumulate in small quantities in almost every part of the body but may be overlooked due to lack of symptoms. Lima has reported on autopsy results of 544 cases of schistosomiasis, of which 96 (17.6%) had “ectopic lesions.” Common clinical lesions are not common parts of the nervous system, eye appendages or skin. Extensive review of literature ENT schistosomiasis is rare, only 4 cases reported, 2 in the posterior pharyngeal wall, 1 in the proliferation of body, 1 case in the throat.
