[Nasal acinar cell carcinoma：a case report]

Acinar cell carcinoma is a rare type of low-grade malignant tumor of the parotid gland epithelium. The progression of the disease is slow, and its tissue type and cell morphology are diverse. The diagnosis of tumor is difficult so that it is easy to cause missed diagnosis and misdiagnosis. A 72-year-old patient, without the history of surgery and trauma, complained of nasal congestion, bloody sputum, and loss of olfactory. CT and MRI suggested that the nasal cavity and sinuses were occupied with soft tissue. An endoscopic nasal cavity and sinus mass resection was performed under general anesthesia. No recurrence was observed after 1 year of follow-up. The nasal symptoms disappeared and the recovery effect was good.
