Nasal rhinosporidiosis masquerading as pyogenic granuloma in a pediatric patient at a Zonal Referral Hospital in Central Tanzania: Case report

Abstract

Being rare, rhinosporidiosis is a chronic granulomatous disease that is characterized by polypoidal lesions of the mucous membrane and is caused by Rhinosporidium seeberi. The disease commonly affects the mucous membrane of the nasopharynx, conjunctiva, and palate and its very rare in our geographical location.

Synchronous nasal rhinosporidiosis and inverted papilloma in a paediatric patient in Dodoma, Tanzania: Case report

“…Nasal rhinosporidiosis refers to a chronic granulomatous disease of the nose that is caused by Rhinosporidium seeberi. [1][2][3][4] The disease affects both human beings and animals and is reported more commonly in hot tropical climates even though it is endemic in India and Sri Lanka. 1,[5][6][7][8] On the other hand, sporadicity has been reported elsewhere such as Brazil, Africa and Argentina.…”

“…8 Regarding race and sex predilection of rhinosporidiosis, there is no racial predominance reported and in terms of sex of predominance, males are more affected than females with the male to female ratio being 4:1. 1,[9][10][11] The disease also affects those individuals aged 15-40 years. 1,2,12 The mode of transmission of rhinosporidiosis may be by direct contact with spores and this can be through dust, infected clothing and swimming in stagnant water.…”

The sporangia when examined in nasal tissue biopsies may be visible at variable stages of maturation.…”
