Conclusion
In conclusion, the low detection rate of fungi often leads to misdiagnosis of AFRS and non-standard treatment. According to the above research, we put forward the following two suggestions for clinical treatment: 1. Improve the detection rate of fungi: including standardized submission of pathological specimens, secretion fungal smears (more than 3 times) and culture, strengthen communication with pathological departments, and fully improve fungal specific examinations such as hexamine silver or Periodic Acid-Schiff  staining, microwave EnVision immunohistochemistry and PCR. 2. When we encounter cases with clinical, radiology, allergic mucin and fungal specific IgE elevation that meet the Bent- Kuhn diagnostic criteria, but no fungal etiological evidence, we can consider treating them according to the principles of AFRS after excluding eosinophilic mucin sinusitis, so as to reduce the recurrence rate and reduce the incidence of complications.
