Lacrimal sac rhinosporidiosis

Rhinosporidiosis is caused by the organism Rhinosporidium seeberi. It is a rare aquatic protistan parasite. Though more prevalent in Asiatic regions, cases have also been reported in European countries. In India, it mostly affects the southern part. Rhinosporidium seeberi most commonly affects the mucous membranes, but can also affect other structures including the larynx, trachea, skin, genitalia, lungs and rectum. The typical presentation is that of a pinkish mass which bleeds profusely. Isolated lacrimal sac rhinosporidiosis is very rare. Computed tomography scans and magnetic resonance imaging are helpful in diagnosis, but histopathological study along with Gomori methenamine silver, periodic acid-Schiff, and potassium chloride are required for confirmation. Its mainstay of treatment is surgery. Prognosis is excellent, but recurrence is not unusua
