title: Management of rare fungal infections.
abstract: OBJECTIVE
  Fungal infections caused by rare fungi have increased in recent years. This may be due to the increase in the number of immunocompromised patients. Some rare fungi are geographically restricted, but with globalization and travel these infections are seen worldwide. The aim of this review is to address recent advances in the management of some uncommon fungal infections.
  
  
  RESULTS
  Dematiaceous fungi (Phaeohyphomycetes) have been reported in both immunocompromised and immunocompetent individuals. Cerebral involvement and disseminated disease are associated with high mortality rates. Surgical excision and broad-spectrum triazole antifungal therapy are associated with better outcomes. Mucormycosis in diabetic and immune-suppressed patients is associated with high mortality. Early radical surgical debridement and amphotericin B-based regimens are a key to success. Basidiobolomycosis has recently been reported to cause chronic granulomatous infection of the gastrointestinal tract. Treatment with itraconazole and surgical resection is associated with favourable outcomes. Invasive fusariosis in cancer patients is typically resistant to most antifungal agents, but recent data have suggested a response to voriconazole. Voriconazole also demonstrated activity against Scedosporium apiospermum, but was less active against Scedosporium prolificans. Amphotericin B and itraconazole are currently the treatments of choice for the southeast Asian fungus, Penicillium marneffie.
  
  
  CONCLUSIONS
  Parallel to the increased number of patients susceptible to invasive infections has been an increase in the number of broad-spectrum antifungal agents allowing for better therapeutic options. High-quality data are lacking because of the rarity of such infections. In future, new triazoles and echinocandins will probably replace amphotericin B as the first therapeutic choice for many uncommon fungal infections.
