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.
