In the last few years an increase has been observed in the incidence of fungal sinusitis in immunocompetent subjects. We present a case of mycotic sinusitis in a 12-year-old patient, in which there were several aspects that could have made the diagnosis more difficult, thus delaying her definitive treatment. This case illustrates how to arrive at a correct diagnosis of this pathology. It must be based on the histological and radiological studies, but always without forgetting a key aspect as it is a suspected diagnosis. The treatment of fungal sinusitis is surgical, and currently, endoscopic sinus surgery is the choice. We describe the clinical characteristics of this pathology and the diagnostic methods required.
