A Case of Rhinosporidiosis and Concomitant Inverted Papilloma - A Review of the Literature - Abstract
Rhinosporidiosis is a chronic granulomatous disease of mucous membranes and is
endemic in Southern India and Sri Lanka, though there are infrequent reports of the
disease elsewhere in the world with Rhinosporidium seeberi identified as aetiological
agent. Sino nasal Inverted papilloma constitutes only 0.5-4% of all nasal tumours
and may be associated with human papilloma virus, chronic inflammation, allergy
and occupational exposures. We present a case in which these two rare pathologies
presented synchronously in a patient presenting with unilateral nasal obstruction
secondary to nasal mass. This is the first case report of rhinosporidium in a white
Caucasian patient without any history of travelling to endemic area. Concomitant
presence of inverted papilloma makes it interesting and supports the inflammatory
theory as a cause for inverted papilloma.
