Lacrimal sac rhinosporidiosis

Rhinosporidiosis is a chronic mucocutaneous granulomatous disease caused by Rhinosporidium seeberi, involving primarily the nose and nasopharynx. Very rarely, the disease can affect the lacrimal sac. Here we report a 35-year-old male patient who had rhinosporidial involvement of the nose 5 years ago, for which he underwent endoscopic nasal surgery. Five years after the excision of the nasal mass, he presented with lacrimal sac involvement. The clinical presentation and the management of lacrimal sac rhinosporidiosis are discussed here.

Rhinosporidiosis in the Americas: A Systematic Review of Native Cases

Rhinosporidiosis is a chronic mucosal infection caused by Rhinosporidium seeberi, an aquatic protistan parasite. It presents as nasal or ocular polypoidal or vascularized masses. It is endemic in tropical and subtropical areas, especially in South Asia; R. seeberi´s endemicity in the Americas is often overlooked. The objective of this study was to describe the demographic and clinical characteristics of patients with rhinosporidiosis in the Americas, its management, and patient outcomes. This study is a systematic review of cases of human rhinosporidiosis in the Americas reported in the literature from 1896 to February 28, 2019. This review screened 1,994 reports, of which 115 were eligible for further analysis. The selected reports described 286 cases of human rhinosporidiosis between 1896 and 2019. Cases were diagnosed in Brazil (32.2%), Colombia (24.4%), Paraguay (12.6%), and the United States (11.9%). The majority of the cases (91%) occurred in geographic areas with altitudes < 1,000 m above sea level and in areas with median temperatures ≥ 25°C (67.3%). Most of the patients presented nasal (65%) and ocular involvement (35%). Surgical treatment was provided for 99.6% of patients, but 19.8% of them recurred. This review describes the under-recognized geographic distribution and clinical presentation of rhinosporidiosis in the Americas and highlights clinical differences to cases in Asia, specifically in reference to a higher prevalence of ocular disease and higher relapse rates.

Trends in Diagnosis of Hydrophilic Pseudofungal Organism Rhinosporidium seeberi- Old to Recent Approach

Rhinosporidiosis is a granulomatous disease with a chronic course, the etiological agent being Rhinosporidium seeberi which usually causes the development of localized lesion in the mucosa of the nose, conjunctiva, and urethra. The disease is prevalent in South India and Sri Lanka although case reports are evident from many parts of the world like Europe, America, and Africa. In the present study, we are reporting a case of rhinosporidiosis elaborating its clinical features, diagnostic modalities, and treatment. Since R.seeberi is not a successfully cultivable organism, in vitro susceptibility of drugs remains a concern. The main focus of the present study is on molecular detection of R. seeberi which can be helpful in the future for early diagnosis and prompt treatment of such cases.

Isolated epiglottic rhinosporidiosis: a rare case report

<p class="abstract">Rhinosporidiosis is a chronic granulomatous disease, caused by <em>Rhinosporidium seeberi</em>. More than 70% of cases are nasal. Usually extranasal rhinosporidiosis is associated with nasal rhinosporidiosis. Isolated extra nasal variety of laryngeal and tracheal rhinosporidiosis are very rare, 7 cases has detected till date. A 45 years male of LSES with habit of pond bath presented to ENT OPD, VIMSAR, Burla, with chief complain of intermittent blood vomiting for last 30 days, associated with foreign body sensation in throat without any dysphagia or dyspnea. On ILE, there is polypoidal pinkish mass studded with white spots found at lingual surface of epiglottis. Ant and post rhinoscopic examination found to be normal. UGIE guided biopsy shows rhinosporiodic mass. Under GA, DL had done mass was excised and base cauterised with bipolar cautery and send for HPE. HPE confirmed the diagnosis. Post operative follow up upto 10 months showed no recurrence. Epiglottic rhinosporidiosis may be one of the differential diagnosis of epiglottic growths especially in endemic zone. Laryngeal involvement of rhinosporidiosis has diagnostic and therapeutic challenges, due to the potential risk of bleeding, aspiration and recurrence.</p>

Raspberry-like tumor on the skin – A rare entity

Rhinosporidiosis is a chronic granulomatous infection, caused by Rhinosporidium seeberi, which frequently affects the nasal cavity and nasopharynx. Cutaneous rhinosporidiosis is rare and probably underreported. We report a case of cutaneous rhinosporidiosis in association with recurrent nasopharyngeal rhinosporidiosis in a 68-year-old male patient.

Lacrimal sac rhinosporidiosis mimicking soft tissue sarcoma: a case report

<div class="WordSection1"><p class="abstract">Rhinosporidiosis is a granulomatous disease caused by <em>Rhinosporidium seeberi</em>, usually affecting the nasal mucosa. Involvement of other sites of body in rhinosporidiosis especially, the lacrimal sac involvement is very rare. Hence, we report a case of lacrimal sac rhinosporidiosis in an adult male patient who presented with infraorbital swelling.</p></div>

Rhinosporidiosis in horses

ABSTRACT: Rhinosporidiosis is a disease caused by Rhinosporidium seeberi, an aquatic protist of the class Mesomycetozoa. It primarily affects the nasal mucosa and transmission is associated with contaminated water contact. This report describes seven cases of rhinosporidiosis in horses in Rio Grande do Sul covering the period of 13 years. The disease predominantly affected Crioulo and thoroughbred horses. No apparent gender predisposition occurs, and age ranged from two to 25 years, with a median of 10 years. The gross aspects were characterized by unilateral (85.7%, 6/7) or bilateral (14.3%, 1/7) polyps. These were soft to friable, whitish to pink, cauliflower-like, with an irregular, sometimes ulcerated surface, measuring 2.5 to 6.0cm in diameter. There was a severe inflammatory infiltrate of the submucosa was observed, associated with moderate proliferation of the epithelium, and numerous rounded structures were identified compatible with sporangia of R. seeberi. Rhinosporidiosis should be included in the differential diagnosis of other conditions affecting the respiratory tract of horses, and it is important to perform histopathology for diagnosis.

An atypical case of rhinosporidiosis: a case report

<p class="abstract">Rhinosporidiosis is an infective chronic granulomatous lesion caused by an organism rhinosporidium seeberi, which is seen endemic in some parts of Asia. This organism is difficult to culture and the diagnosis is based on histopathological examination. This disease is more commonly seen in men, in second to third decade..<strong> </strong>This case report is regarding a case of a 55 years old lady with history of recurrent rhinosporidiosis in nose. The lesion was found to arise from the inferior meatus and was pale smooth glistening in appearance, insensitive and does not bleed on touch. Site of origin of the polyp and the appearance was atypical of that of rhinosporidiosis. Patient was subjected for endoscopic excision and cauterisation of the base of the lesion and sent for histopathological examination .Biopsy confirmed the diagnosis of rhinosporidiosis.</p>
