Ma H, et al. - The authors scrutinized the pathological classifications and management of accessory parotid gland (APG) lesions in the hospital. It was noted that the masses in the APG region presented with complicated pathological types. In order to detect the characteristics, perfect preoperative preparation, with fine-needle aspiration biopsy and imaging examinations, would serve as contributory factors. Hence, the determination of treatment schedules and surgical approaches was recommended according to the cytology reports and frozen-section examinations before and during operation.

Methods

• The eligible candidates included 130 patients with primary tumors in the APG region who underwent surgical treatment, who were recruited from January 1993 to March 2017.
• Researchers then performed follow-up surveys after surgery.

Results

• It was noted that 53.8% of lesions were benign (n = 70), 23.8% were malignant (n = 31), 14.6% were vascular malformations (n = 19), 6.15% were sialadenitis (n = 8), and 1.65% were cysts (n = 2).
• The yielded data unveiled that pleomorphic adenoma accounted for 67.1% of the benign tumors (n = 47).
• Lymphoma, lymphoepithelial carcinoma, and acinar cell carcinoma were placed at the top of the malignant tumors' (n = 5, respectively) list.
• Experts carried out surgery and surgery plus radiochemotherapy for benign and aggressive malignant lesions, respectively.
• The five-year overall survival was determined to be 88.1% and the mean follow-up was 139 months (range 3-281 months), at the time of follow-up.
