Histopathologically confirmed ocular rhinosporidiosis in two Canadians

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.

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.
