The causes of false-negative diagnosis are, inappropriate selection of portion of polyps containing scanty or no rhinosporidial tissue, though other portions contain rhinosporidial bodies, absence of well-developed bilamellar thick rninosporidiosis of sporangia, presence of only fragments of outer wall without endospores, and absence of typical rhinosporidial bodies as a result of possible rhknosporidiosis reactions. CT Scan of paranasal sinuses axial cut showing soft tissue density mass filling the left nasal cavity, maxillary antrum and extending into the nasopharynx.

Fine needle aspiration cytology FNAC of the lesions was available in only a few cases. In arid countries most infections are ocular and dust is postulated to be a vector. Charles, in Diagnostic Pathology of Infectious Disease Second EditionRhinosporidiosis Rhinosporidiosis is caused by infection with the fungus Rhinosporidium seeberiwhich leads to the formation of a distinctive highly vascular, polypoidal, or pedunculated mass of the mucous membranes studded with white, subepithelial sporangia Fig.


These features are in accordance with the observations of other workers and is a possible reflection of more outdoor activities.

Primary cutaneous rhinosporidiosis diagnosed on FNAC: Blastomyces dermatitidis Blastomycosis North American blastomycosis South American blastomycosis Sporothrix schenckii Sporotrichosis Penicillium marneffei Penicilliosis. After inoculation, the organism replicates locally, resulting in hyperplasia of host tissue and localised immune response.

Interestingly, as is the case in R.

Clinicopathological study of rhinosporidiosis with special reference to cytodiagnosis

In our series, 17 cases were initially evaluated on cytology either by aspiration or with combined aspiration and scrape cytology. The only drug appearing to have clinical promise is Dapsone [ 18 ]. Epidemiology Frequency United States. Gautam Bandyopadhyay 1 Department of Pathology, R.

Although the infection is more commonly diagnosed in Asia, rhinosporidiosis was first reported in South America by Guillermo Rodolfo Seeber in two Argentine patients studied by him in72 but he did not name the rhinowporidiosis.

Fungal infection and mesomycetozoea B35—B49— Diagnosis was confirmed by demonstration of endospores and sporangia, as reported by other workers.

It arrests the maturation of sporangia and promotes fibrosis in the stroma, when used as an adjunct to surgery [ 2 ]. Initially thought to be a parasite, for more than 50 years R seeberi had been considered a water mold. Allergic rhinitis in cattle must be differentiated from maduromycosis, rhinosporidiosisand infection with the pasture mite Tyrophagus palmarum. Papillomatous hyperplasia and increased vascularity may also be seen in these lesions.

Abstract Rhinosporidiosis is a disease caused by Rhinosporidium seeberi which rhinosporidiosix affects the mucosa of the nose, conjunctiva and urethra. This organism was previously considered to be a fungusand rhinosporidiosis is classified as a fungal disease under ICD Excised mass Click here to view. Lesions increase in size over months to years to form friable pedunculated masses, typically in the nose, upper airway, or conjunctiva.

Isolated cases of dissemination involving deep organs have been rarely reported. The most prevalent location of the disease is the nasal cavity. It usually presents as a soft polypoidal pedunculated or sessile mass.
