Severe epistaxis from rhinosporidiosis: a case report.

Rhinosporidiosis is quite rare in Thailand, but the actual incidence may be higher than the numbers reflect. This is thought to be due to misdiagnosis by physicians who are unfamiliar with this disease entity or physicians who found a case but did not describe its presence. The authors report a case in a 17 year old male with the lesion involving both nasal cavities, nasopharynx and left maxillary sinus presenting with severe epistaxis, which was treated by complete surgical removal with electric cauterization of its base. We warn physicians who face this problem to be aware of this disease entity.
