Case Series: We hereby report three cases of fungal sinusitis caused by uncommon Aspergillus
such as A. versicolor and A. sydowii. Case 1 was a 40-year-old female came with complaints
of nasal block and nasal discharge for past one and a half years with history of previous
nasal surgery. Her computed tomography (CT) scan of paranasal sinus (PNS) showed bilateral
ethmoidal sinusitis. Case 2 was a 43-year-old male known asthmatic presented with complaints
of nasal block for last fve years, was diagnosed to have bilateral sinonasal polyposis by anterior
rhinoscopy. Case 3 was a 17-year-old female known asthmatic presented with headache, nasal
discharge and frequent sneezing for last six months. Her CT PNS showed left side deviated
nasal septum with left side pan sinusitis along with right frontal sinusitis. All the three patients
underwent functional endoscopic sinus surgery (FESS). The material was sent to the microbiology
laboratory for fungal culture and potassium hydroxide mount. Speciation by slide culture was
not conclusive. Hence, molecular methods were opted for speciation.
