MAXILLARY SINUS MUCORMYCOSIS MIMICKING SINUS MALIGNANCY
چکیده
Mucormycosis is an opportunistic fulminant fungal infection in diabetic and immunocompromised patients. The infection is acquired in the nose and paranasal sinuses by the inhalation of the fungal spores. We report of a case of maxillary sinus mucormycosis in a 32-years-old non diabetic woman. She had right side facial pain, headache, unilateral right side nasal obstruction, and post nasal discharge (PND) for five years. Nasal endoscopy revealed pus and granulation tissue, and semi-black middle turbinate in right side nasal cavity. Computed tomography showed bone erosion and a large soft tissue mass similar to sinus carcinoma in maxillary sinus with extension into the ethmoidal sinus. She underwent functional Endoscopic sinus surgery. Macroscopically, the specimen consisted of multiple tissue fragment 0.8-1 cm. Microscopic findings included an inflammatory cells and deposited fungal elements (mucormycosis). So in the paranasal sinus and nasal cavity mass, mucormycosis should be included in the differential diagnosis, especially in the non diabetic and young patients.
