[A case of rhinosporidiosis].
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.
