Abstract

Objectives: This study was conducted to report clinical and subclinical features of parotid gland cancer at K Hospital. Patients and methods: A retrospective, descriptive study on 54 patients with parotid gland cancer were treated in K hospital from 01/2016 to 12/2020. Results: The mean of age was 49.6; male/female ratio was 1.25/1. The reason which patients was admitted to hospital was palpation a mass at parotid gland 85.2%; time from first symptom to diagnosis within 6 months was 75.9%. The common symptoms are pain (46.3%) and palpation a mass at parotid gland (53.7%). Clinical examination showed that the tumor size was mainly from 2-4cm (57.4%); The hard density of tumor was 90.7% and the rate of tumor mobility was 61.1%. On ultrasound, tumors were mostly hypoechoic (85.2%), neck lymph node metastases were found in 40.7% of patients. The percentage of positive cytology was 68.5%. Histopathology results showed that the most common pathology were mucoepidermoid carcinoma (46.3%) and adenoid cystic carcinoma (16.7%). Conclusions: Parotid gland carcinoma usually appears in middle-age patients, detected mainly through palpation, when the tumor is 2-4 cm in large. Ultrasound is a simple method to guide to diagnose. The parotid cytology is valuable in the diagnosis of parotid gland cancer.
