Abstract

Mycotic infections of the nasal cavity and paranasal sinuses represent a wide spectrum of disorders that vary in clinical presentation, histopathologic appearances, and biological significance. The second most common form is a fungal ball.

The objective of the research was to describe the cases of paranasal sinus fungal ball found in the files of patients with chronic rhinosinusitis.

Materials and Methods. There were demonstrated clinical and histopathological data of two patients.

Results. A 42-year-old woman and a 40-year-old man with chronic hypertrophic sinusitis had a large amount of friable cheesy mass in the maxillary sinus. The female patient previously underwent upper dental arch sanation. Histology revealed dense laminated masses of matted fungal hyphae that were separate from the mucosa. Sinonasal mucosa showed mild chronic inflammation (male) and severe non-specific chronic active inflammation (female). No evidence of fungal invasion in the mucosa was found.

Conclusions. Fungal ball represents a non-invasive form of mycotic rhinosinusitis with favourable prognosis. Biopsy examination plays an important role in the diagnostic process. Although the diagnosis can also be achieved by polymerase chain reaction assays, biopsy is the only way to explore the status of an inflammatory damage to adjacent tissue and, thus, to rule out potential invasive mycotic sinus disease with much worse clinical outcome.
