ABSTRACT
The aim of this study was to assess the prevalence of fungal infection in nasal polyps and highlight the role of fungal culture in comparison with the histological evaluation in identifying fungal infections This was a descriptive study conducted over a period of one year from 1st January 2008 to 31st December 2008 during which consecutive samples of nasal polyps were examined. Only those samples were included in the study which were received in two containers, containing 10% formalin and normal saline, for histopathological examination and microbiological evaluation respectively. Results were recorded on a proforma containing age, sex, histological findings and results of culture. A total of 42 samples were studied. Nasal polyps were found to be more common in males as compared to females. They were predominantly common in adults with mean age of 23.7 years. Positive culture for fungus was seen in 25 cases with Aspergillus spp was the most common isolate seen in 19 cases. Out of 25 culture positive cases, only 12 were identified on histology slides using special stains. There was increased prevalence of fungal infections in nasal polyps and this may explain the etiology as well as the frequent recurrences associated with nasal polyps. The importance of fungal culture has been highlighted in final identification of fungus. So it is recommended that all nasal polyps be simultaneously examined both histopathologically and microbiologically for effective clinical management
