RESUMO
Allergic fungal rhinosinusitis (AFRS) is a non-invasive fungal sinusitis resulting from an immunologic response to the presence of extra mucosal fungal hyphae in the sinuses. Here we studied clinicopathological characteristics of AFRS among patients of chronic rhinosinusitis with nasal polyposis who underwent Functional Endoscopic Sinus Surgery (FESS) at a tertiary care in western Rajasthan. Standard ethical protocol was followed for the present study. We did a prospective study on admitted patients of chronic rhinosinusitis with nasal polyposis in the department of Otorhinolaryngology and Head & neck surgery, Dr. S. N. Medical College, Jodhpur from January 2018 to August 2019, who underwent FESS. The patient's history, clinical and endoscopic findings with radiological features were recorded. Biopsy specimens were sent for fungal staining, culture, and histopathology. As per Bent and Kuhn criteria, 25 cases out of 100 were diagnosed as AFRS, mean age was 27.46 ± 13.36. Nasal obstruction and nasal discharge were the most common symptoms. On histopathological examination fungal hyphae found in 18 cases (72%), allergic mucin in 25 cases (100%) and eosinophilic infiltrate in 20 cases (80%). Fungal culture positive in 15 cases (60%) of AFRS. In which aspergillus flavus present in 12 (80%). Allergic fungal rhinosinusitis should be considered as an important differential diagnosis in patients with chronic rhinosinusitis with nasal polyposis and for this surgery should be the treatment of choice.
