A patient (46 years old, male) with a 5-month history of progressive right nasal obstruction was admitted in June 12, 2015. He appeared rhinobyon on right side because of a cold 5 months ago. His nasal congestion gradually increased, until the right nasal cavity was completely blocked. He rarely had a runny nose, but sometimes had a headache on the right side. Sinoscopy revealed a light reddish, rough and tough mass which totally occupied his right limen nasi and could not be contracted by decongestant. Nasal endoscopy could not enter the right nasal cavity after using decongestant. Sinus computed tomography (CT) scan showed a homogeneous mass in the right nasal cavity without bony erosion [Figure 1A]. The patient had no history of hypertension, diabetes and coronary heart disease. Diagnosis: benign tumor of the nasal cavity (right). Making sure no taboo, we arranged endoscopic exploratory operation for this patient in June 15, 2015. During the operation, the tumor was broken when pulled by the cutting forceps. The tumor soon shrunk after about 5 to 6mL milky fluid flowed out from it. With the assistance of elevator, the pedicle of the tumor was found in the right uncinate process [Figure 1B] and then was removed [Figure 1C]. The uncinate process stump was properly handled with electrocautery [Figure 1D]. Gelatin sponge was used to pack the operation cavity. The pathology report proved the diagnosis of mucous gland cyst [Figure 1E]. The patient was discharged 5 days later. Twelve months after operation, the nasal mucosa was recovered well.
