Fungal rhinosinusitis: A prospective study in a University hospital of Uttar Pradesh.

Background: To assess the purpose of fungal rhinosinusitis in a University hospital and to correlate histopathological findings with culture results for accurate clinical classification of the disease. Materials and Methods: One-hundred suspected patients were included in the study. Data was collected in a brief predetermined format. Samples like nasal lavages, sinus secretions, and tissue specimens were processed and examined by microbiology culture using recommended techniques. Slide culture was done to observe the microscopic morphology. Histopathological examination was done by H and E stain and PAS stain for classification. Results: Out of 100 cases of rhinosinusitis, 21 cases were culture-positive for fungal rhinosinusitis. On the basis of histopathological findings, 14 cases (66.67%) were found to be of non-invasive fungal rhinosinusitis. Aspergillus flavus was the most common fungal isolate. Conclusion: Mycological profile of rhinosinusitis in Lucknow was thus evaluated. Histopathological and microbiological findings reported 21 cases of fungal rhinosinusitis among 100 suspected cases of rhinosinusitis.
