“…Ocular recurrences are typically rare, with 1% rate for the conjunctiva, and between 2 and 40% for the lacrimal sac [26, 27, 32]. The causes: are incomplete excision of the lesion and spreading of endospores to the adjacent sites during a surgical procedure [14, 33]. The ineffective cauterization of the base of the lesion and failure to use dapsone in the postoperative period may make the lesion more susceptible to relapses.…”

BackgroundOculosporidiosis (ocular rhinosporidiosis) accounts for 15% of cases of rhinosporidiosis, which is a chronic granulomatous disease and is endemic in India and Sri Lanka. In Brazil, the climatic and hydrographic similarities to these endemic areas and the presence of riverside populations contributes to an increase in the incidence of rhinosporidiosis particularly in the State of Maranhão. This study, therefore, aimed to identify the number of diagnosed cases of oculosporidiosis and describe its the clinical epidemiology, laboratory, histopathology, and therapeutic characteristics.MethodsThe study is descriptive, observational, and cross-sectional, and reports the prevalence and clinical epidemiological characteristics of oculosporidiosis in the State of Maranhão, Brazil. A retrospective analysis of the paper and electronic records for a period from 1999 to 2017 was conducted in the University Hospital of Federal University of Maranhão (HU-UFMA), located in the northeastern region of Brazil.ResultsThirty patients were diagnosed with rhinosporidiosis, eight of them had oculosporidiosis and seven of these met the criteria to be included in the study. Of the cases (23.3% of all 30), five were men (71.4%) and two women (28.5%), with an average age of 16.4 ± 15.6 years. In terms of race, four patients (57.1%) declared themselves white and three (42.9%) as brown. The north of the state, the mesoregion, had the most diagnosed cases accounting for 57.1% of the total. Left eye was the most affected site, reported in six patients (85.7%), while the conjunctiva was affected in all patients. Rhinosporidiosis and papilloma were the predominant diagnostic hypotheses (28.5 and 28.5%, respectively), followed by chronic scleritis, granuloma, and chalazion (14.25, 14.25, and 14.25%, respectively). All these cases were treated with lesion excision, and only two patients (28.5%) progressed with recurrence.ConclusionIt was verified that there was a male predominance, with only one eye reported as an infected site, with no bilateral involvement. The younger age group (between 1 and 2 years of age) was more affected by oculosporidiosis, and histopathological examination was necessary for a conclusive diagnosis.

“…The first case of rhinosporidiosis of the parotid duct was reported by Topazian RG in the year 1966 [7] . Involvement of the stensen's duct is rare and only few cases reported in the literature in last 10-years [8][9][10][11][12][13] . In most of the the published case reports, patients usually presented with a cystic swelling in the cheek and were provisionally diagnosed as stensen's duct cyst [7,[8][9][10][11][12][13][14][15] .…”

“…The sporangia and sporangiospores of the organism can be highlighted by typical fungal stains such as Gomori Methenamine Silver(GMS), Periodic Acid-Schiff (PAS), and mucicarmine as well as with standard haematoxylin and eosin stain. Mucicarmine is particularily helpful in differentiating Coccidioidesimmitis as its sporangia and spores do not stain positively [9] . Also intrasporangial endospores of R.seeberi are larger and more numerous than in C.immitis [5] .…”

Rhinosporidiosis is a chronic granulomatous infective disease caused by fungi, Rhinosporidium seeberi. It occurs universally and is endemic in India, Sri Lanka and in South Asia. Rhinosporidiosis classically involves anterior nares, nasal cavity, nasopharynx, larynx and soft palate and presents as a localized polypoid mass. However Rhinosporidiosis involving parotid duct is rare. The case discussed here is of a 55-year-old male who presented with a sudden onset of unilateral facial swelling associated with on and off pain during mastication. Cytological findings was inconclusive and was suggestive of retention cyst. Although rhinosporidiosis was not taken into consideration in the clinical differential diagnosis, histopathological diagnosis confirmed the case to be rhinosporidiosis.

“…Soft palatal lesions are common in oral rhinosporidiosis cases. Few reports have been reported with parotid duct involvement [ 76 , 79 ]. Cases that show proliferative growth in parotid papillae regions should be suspected for oral rhinosporidiosis [ 76 ].…”

The frequency of fungal infections is increasing due to immunodeficiency viruses and immunosuppressive drugs. The most common fungal infection of the oral cavity is candidiasis. The existence of Candida can be a part of normal commensal; hence, the isolation of Candida in the absence of clinical symptoms should exclude candidiasis. The pathogenicity of Candida is witnessed as opportunistic when immune status is compromised. Oral fungal infections are uncommon, but when identified, these infections are associated with greater discomfort and are sometimes destruction of tissues. Cytology and tissue biopsy are helpful in confirming the clinical diagnosis. The management of oral fungal infections must strategically focus on signs, symptoms, and culture reports. This article reviews information on diagnosis and therapeutic management of aspergillosis, cryptococcosis, histoplasmosis, blastomycosis, mucormycosis, and geotrichosis.
