Rhinosporidiosis is due to fungal infection by Rhinosporidium seeberi, which affects predominantly the mucous membrane of the nose and nasopharynx. This disease is characterized by the formation of papillomatous and polypoid lesions and is known to be endemic in India and Sri Lanka. The first case of rhinosporidiosis in Japan is reported in this paper. A 25-year-old male Indian, born in India, living in Japan for a year, visited the outpatient clinic complaining of nasal obstruction and swallowing pain. A friable, irregular, reddish polypoid mass was found in the right nasal cavity. Endoscopy as well as plain X-ray and CT examination showed that the mass originated from the right inferior turbinate and extended into the choana without any sign of bone destruction. The mass removed under general anesthesia showed the typical feature of rhinosporidiosis, that is, papillomatous hyperplasia of the mucosa with sporangia full of spores in different stages of development. One year after treatment, no relapse has been seen in this case.
鼻孢子虫病是由西伯鼻孢子菌真菌感染引起的，主要影响鼻腔和鼻咽部的黏膜。这种疾病的特征是形成乳头状和息肉样病变，在印度和斯里兰卡为地方病。本文报道了日本首例鼻孢子虫病病例。一名25岁的印度男性，出生于印度，在日本生活了一年，因鼻塞和吞咽疼痛前往门诊就诊。在右侧鼻腔发现一个易碎、不规则、红色的息肉样肿物。内镜检查以及普通X线和CT检查显示，肿物起源于右下鼻甲并延伸至后鼻孔，无任何骨质破坏迹象。在全身麻醉下切除的肿物显示出鼻孢子虫病的典型特征，即黏膜乳头状增生，伴有充满处于不同发育阶段孢子的孢子囊。治疗一年后，该病例未见复发。
