Conclusion
In Tanzania, rhinosporidiosis is non-endemic and in the Central zone,
the disease is uncommon thus may pose diagnostic challenges. Sinonasal
inverted papillomas are also rare in our settings. Presence of
synchronous rhinosporidiosis and inverted papilloma supports the
inflammatory theory for pathogenesis of inverted papilloma. It is
therefore important for both clinicians and pathologists to have a high
index of suspicion when managing patients with nasal masses even from
non-endemic areas.
