17 May Rhinosporidiosis is a disease caused by the organism Rhinosporidium seeberi, which was once thought to be a fungus but is now believed to. 18 May Nasal cavity, paranasal sinuses, nasopharynx – Rhinosporidiosis. Rhinosporidiosis is a chronic infective disorder caused by Rhinosporidium seeberi. It usually presents as a soft polypoidal pedunculated or sessile mass.

Clinicopathological study of rhinosporidiosis with special reference to cytodiagnosis

Aspirations were done by using standard methods with gauge needles to reduce the chance of bleeding. Indian J Med Microbiol. The disease is endemic in wet tropical and subtropical environments, uncommon in North America and Africa, and rare in Europe.

J Submicros Cytol Pathol. Primary lacrimal sac rhinosporidiosis with grossly dilated sac and nasolacrimal duct.

The patient was discharged and was later lost to follow up. Webarchive template wayback links Infobox medical condition. After inoculation, the organism replicates locally, resulting in hyperplasia of host tissue and localised rhinopsoridiosis response.

Pathology Outlines – Rhinosporidiosis

These features are in accordance with the observations of other workers and is a possible reflection of more outdoor activities. This study rhinosoridiosis and reports for the first time the incidence of nasal rhinosporidiosis in the region of East Delhi. The affected patient usually develops pedunculated, unilateral, polypoid masses in the nasal cavity inferior cornet, septum, nasal floor, medium cornet, meatus and nasal roof which can be lobulated and confluent.

Secondary bacterial infection can cause morbidity. The whole mass was sent for histopathological and microbiological study and the patient was placed on Dapsone, mg once daily, for 6 months.

Charles, in Diagnostic Pathology of Rhknosporidiosis Disease Second EditionRhinosporidiosis Rhinosporidiosis is caused by infection with the fungus Rhinosporidium seeberi rhinospporidiosis, which leads to the formation of a distinctive highly vascular, polypoidal, or pedunculated mass of the mucous membranes studded with white, subepithelial sporangia Fig.


The most common age group affected was years [ Table 1 ].

It usually presents as a soft polypoidal pedunculated or sessile mass. Rhinosporidiosis is a chronic infestation by the fungus Rhinosporidium seeberi rhinosporidiosos, which predominantly affects the mucus membranes of the nose and nasopharynx.

A study that resolves etiologic controversies. We use cookies to help provide and enhance our service and tailor content and ads.

Though now related to a group of fish parasites referred to as the DRIP clade, most microbiologists initially considered it a fungus on the basis of its property to be stained by fungal stains such as GMS and PAS [ rhinowporidiosis ]. Conclusion Morphological appearance alone in a few cases failed to give diagnosis of rhinosporidiosis. Fine needle aspiration rhinosporidiosi FNAC of the lesions was available in only a few cases. Mucorales Mucormycosis Rhizopus oryzae Mucor indicus Lichtheimia corymbifera Syncephalastrum racemosum Apophysomyces variabilis.

Rare sites of involvement in our series were lip, palate and urethra. CT picture shows bilateral nasal mass with bilateral maxillary sinus haziness Click here to view.

Cutaneous lesions are usually associated with other affected sites and present with a soft variegated consistency, which may ulcerate when pedunculated. Mature sporangium with multiple endospores. Cutaneous lesions are rare, even in India, Sri Lanka, and South America, where the causative agent, Rhinosporidium seeberiis endemic. The name Coccidium seeberia was a binomial given to this pathogen by Seeber’s former adviser Wernicke.

Characterization of Candida species isolated from the hands of the healthcare workers in the neonatal intensive care unit.

Nasal rhinosporidiosis. – PubMed – NCBI

Rhinosporidiosis rhinos;oridiosis caused by Rhinosporidium seeberi, which causes slow-growing tumor-like masses in the nasal cavity. Please review our privacy policy. Data on antimicrobial drug resistance in Rhinosporidium seeberi is lacking.


There is a slight male predominance in patients with nasal disease. Nil Conflict of Interest: With no significant travel history to the known endemic states of India for rhinosporidiosis, nor having any contact with infected patients as per the history given by them, we presumed that the patients in our cases acquired the infection locally.

The etiological agent is Rhinosporidium seeberiwhose taxonomy has been debated in the last decades since the microorganism is intractable to isolation and microbiological culture [ 3 ]. Rhinosporidiosis is a chronic, usually painless localized infection of the mucous membranes.

Collapsing rhinosporidioxis or main-stem bronchus Trauma, rhinisporidiosis, foreign body, neoplasia Small airway disease Feline asthma Bronchitis Smoke inhalation Bronchopneumonia.

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. Phylogenetic analysis of Rhinosporidium seeberi’s 18S small-subunit ribosomal DNA groups this pathogen among members of the rhinosporidoisis Mesomycetozoa clade. Histopathology in rare instances may fail to diagnose rhinosporidiosis. Phylogenetic position and ultrastructure of two Dermocystidium species Ichthyosporea from the common perch Perca fluviatilis Archived at the Wayback Machine.

The differential diagnoses include coccidioidomycosis, myospherulosis and pyogenic granuloma. Although once thought to be a fungus, molecular methods have identified this organism as an aquatic protistan parasite class Mesomycetozoea. Uncommon features noted in our cases were warty growth in the lips, palate and urethra, nasal infection with abscess formation, and anosmia.
