Histopathologically confirmed ocular rhinosporidiosis in two Canadians

Case report: In India and Southeast Asia, rhinosporidiosis is a common infectious disease, but it has rarely been reported in western countries. Infrequently, isolated ocular rhinosporidial infections have been reported, but to our knowledge, there are no reported cases in Canada. Two cases of rhino...

Description
Summary:Case report: In India and Southeast Asia, rhinosporidiosis is a common infectious disease, but it has rarely been reported in western countries. Infrequently, isolated ocular rhinosporidial infections have been reported, but to our knowledge, there are no reported cases in Canada. Two cases of rhinosporidiosis have been recently diagnosed and managed at our university-based hospital. Comments: Rhinosporidiosis presents with certain characteristic clinical features; however, the diagnosis is confirmed histopathologically. The presence of typical sporangia and spores in a fibrovascular stroma infiltrated by acute and chronic inflammatory cells including granulomas is diagnostic. Surgical excision is the treatment of choice, and recurrence is possible but rare. Observation: La rhinosporidiose est une maladie infectieuse courante en Inde et en Asie du Sud-est, mais rarement rapportée dans les pays occidentaux. Il est peu fréquent qu’on fasse état d’infections oculaires de cette nature et, à notre connaissance, on n’en a signalé aucun cas au Canada. Deux cas de rhinosporidiose ont été diagnostiqués et traités à notre hôpital universitaire. Commentaires: La rhinosporidiose présente certaines caractéristique cliniques particulières; le diagnostic est cependant confirmé par un examen histo-pathologique. La présence de sporangia et de spores typiques dans un stroma fibrovasculaire infiltré de cellules inflammatoires aiguës et chroniques comprenant des granulomes en permet le diagnostic. L’excision chirurgicale est le traitement de préférence; la récurrence est possible mais rare.
