Clinicopathological study of rhinosporidiosis with special reference to cytodiagnosis
The most prevalent location of the disease is the nasal cavity. It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide. The prognosis is excellent, with only occasional recurrences. Moreover, given the modern day propensity for travel and the ability of these agents to remain dormant for years, infections acquired by patients in restricted geographic regions can manifest symptoms outside of that area.
The present study was conducted in the pathology department of a rural medical college for a period of 2 years from March to February The Athlone Press; The causative organism has been identified by genetic techniques as a member of the aquatic Protista .
Nasal polyps need to be differentiated from those in allergic disease. Rhinosporidiosis is a chronic and localized infection of the mucus membranes and the lesions present clinically as polypoid, soft masses sometimes pedunculated of the nose, throat, ear, and even the genitalia in both sexes. Mature sporangium of Rhinosporidium seeberi.
We report a case of rhinosporidiosis with presentation as a mass extending up to the oropharynx. Analysis of 27 cases.
Light and electron microscopic findings in rhinosporidiosis after Dapsone therapy. This finding was evident in our series of cases as two of the three cases were in young adults and all three were males. The studies of Silva et al 86 further validated the idea that R.
Rhinosporidiosis – Wikipedia
The aim of this study is to present the clinicopathological features of rhinosporidiosis in a large series of cases and to asses the role of cytology in diagnosis. Hortaea werneckii Tinea nigra Piedraia hortae Black piedra. Ground water is considered to be the natural habitant of R. Rhinitis is readily recognizable clinically. Pathologic Features Gross Findings Rhinosporidiosis typically manifests as friable nasal polyps or masses, classically described as strawberry-like in appearance.
Nevertheless, rhinosporidiosis continues to be an enigma and a large number of further studies from endemic and non-endemic areas are needed. Infection probably develops as a result of direct exposure to stagnant water, although inhalation of spores may also play a role.
The phylogenetic studies of Silva et al 86 also found the presence of species-specific strains in the genus Rhinosporidiuma finding that could forecast the existence of novel host-specific species. Primary pulmonary coccidioidomycosis Histoplasma capsulatum Histoplasmosis Primary cutaneous histoplasmosis Primary pulmonary histoplasmosis Progressive disseminated histoplasmosis Rhinosporidiois duboisii African histoplasmosis Lacazia loboi Lobomycosis Paracoccidioides brasiliensis Paracoccidioidomycosis.

Un neuvo esporozoario parasito del hombre: Data on antimicrobial drug resistance in Rhinosporidium seeberi is lacking. Indian J Med Microbiol. Rhinosporidiosis has been known for over years since its first description in Rhijosporidiosis. Affects the mucous membranes of the sinonasal tract and less commonly conjunctiva, upper airway, genital tract, and other sites. There is some evidence that host-specific strains of R.

J Trop Med Hyg. Nasal rhinosporidiosis in two dogs native to the upper Mississippi river valley region. It was strawberry-like in appearance with occasional grayish areas. Rupture of sporangia can cause giant cell reaction. Patients of any age can be affected, but it is most commonly encountered in patients in their third and fourth decades.
