Chronic Invasive Sinonasal Mucormycosis; A Rare Disease Entity

Mucormycosis is a rare invasive fungal infection of the nose and paranasal sinus, which often has an acute fulminant course and distinctive clinical findings. It usually occurs in diabetics or immunocompromised patients and shows rapid progression with a high mortality rate. Slow, silent progression is a highly unusual presentation of this disease. Herein, we report a case of mucormycosis with a chronic course of invasion into the hard palate and the maxillary sinus.
