RHINOSPORIDIOSIS Ở MŨI: BÁO CÁO CA BỆNH VÀ TỔNG QUAN Y VĂN

Abstract

Objective: We present a rare case description of a 49 year old male with a polypoid nasal rhinosporidiosis. Method: Case report and review of the world literature. Results: Rhinosporidiosis is a chronic granulomatous disease affecting the mucous membrane primarily and is caused by Rhinosporidium seeberi, a pathogen currently considered a fungus-like parasite of the eukaryotic group Mesomycetozoea. It is usually a benign condition, with slow growth of polypoid lesions, with involvement of the nose, nasopharynx, or eyes. Nasal rhinosporidiosis is uncommon disease in our environment which mimics neoplasm in its clinical features. The organism is difficult to culture and the diagnosis is based on microscopy and histological examination of the lesion. The treatment of choice is complete surgical excision along with cauterisation of base to prevent the recurrence. Dapsone that interferes with maturation of spores has been used in preventing the recurrence. Conclusion: Nasal rhinosporidiosis lesions may largely mimic other ordinary nasal polyps. Diagnosis was confirmed by histopathological examination. The patient was successfully treated by complete surgical excision.
