“…Primary and secondary malignant tumors constituted 7% and 4% of the whole group and the most frequent primary malignant tumor was mucoepidermoid carcinoma (Table 1). Although the ratio of the malign tumors is less than the literature data, tumor distribution of the study is compatible with the literature [1]. This results can be explained by the small number of study group.…”

“…Comparing them with the definite post-operative histopathological results showed a sensitivity of 72% to identify cases of malignancy and specificity of 100%, without any false positive case. Although the specificity ratio was higher than the literature, our sensitivity rates were lower when it was compared with the other studies [1,9]. Either the higher sensitivity and lower specificity rates can be explained with the high rate of the patients with cytologically non-classified lesions.…”

“…Parotid tumors, which account for 2-3% of all head and neck tumors, occur at a frequency of 1/100,000 and constitute up to 80% of all salivary gland tumors [1][2][3]. Of all the salivary gland tumors, 75% of them are benign and 25% of them are malignant.…”

Objective: In this study, we aimed to evaluate clinical presentations, histopathological diagnosis, surgical treatment modalities and complications of patients operated for a parotid gland mass. Methods:Medical records of 100 patients who were operated for a parotid gland mass between 2010 and 2016 years evaluated retrospectively.Results and discussion: 49 (49%) of these patients were female and 51 (51%) were male. The mean age of the patients was 47.9. Post-operative histopathologic assessement, 89 of the cases were found to be primary benign, 7 of the cases primary malignant and 4 of the cases secondary malignant. For benign tumors the most common histopathology was pleomorphic adenoma in 45 (45%) patients, and the second was whartin tumor in 32 (32%) patients. Mucoepidermoid carsinoma was seen as the most common primary malign tumor (3 patients). All cases with primary malignancy continue to follow-up visits and the average follow-up period is 37 months. However, all of the cases with secondary malignant parotid tumors were died due to malignancy. Complication ratio was 12% and facial paresis was the most common complication. Conclusion:Subtotal parotidectomy is an adequate and efficient surgical procedure for the benign parotid tumors and complication risk is considerably low when applied carefully. However it may be required complementary total parotidectomy for malignant tumors. The prognosis is very good especially for the primary malign parotid tumors. However, it is not satisfactory for the secondary malign tumors.

“…Parotis kaynaklı kitlesi olan hastaların literatürdeki ana yakınmaları hastalarımızda da olduğu gibi parotis bölgesine uyan alanda kitledir. Parotis kitlelerinde palpasyon; kitlenin lokalizasyonunu belirlemede, kitlenin sertliğini, çevre dokuyla ilişkisini, yüzey yapısını anlamada, lobülasyonlarını hissetmekte, sınırlarının düzenlili-ğini tespit etmede ve benign-malign ayrımında çok değerli bir klinik parametredir 6 . Malign vakalarda ağrı, fasiyal sinir paralizisi ve parotis üzerindeki ciltte tutulumlar ortaya çıkabilir.…”

ObjectiveTo retrospective analysis of the epidemiological and clinical characteristics of parotid gland tumors, and to explore the value of ultrasound in the differentiation of benign and malignant parotid gland tumors.MethodsThe clinical data of 350 patients with parotid gland tumors in our hospital from 2002 to 2022 were retrospectively analyzed. These patients were examined by ultrasound. The postoperative pathological test results were used as the “gold standard” to verify and analyze the value of color Doppler ultrasound in the differential diagnosis of benign and malignant parotid tumors (PT).ResultsThe male‐to‐female ratio of 350 patients with parotid gland tumors was 1.16:1. The age of patients ranged from 12 to 87 years old. Patients aged 40–65 years accounted for 54.6%, which was the most common age of parotid gland tumors. Among 350 cases, 259 were benign and 91 were malignant. The top three benign PTs were pleomorphic adenoma, Warthin tumor, and basal cell adenoma. The top three malignant tumors were mucoepidermoid carcinoma, acinar cell carcinoma, and adenoid cystic carcinoma. The specificity, sensitivity, accuracy, positive predictive value, and negative predictive value of ultrasonography in the diagnosis of benign and malignant parotid masses were 96.53%, 69.23%, 89.43%, 87.50%, and 87.72%, respectively.ConclusionThe pathological types of parotid gland tumors are complex and diverse. Ultrasonography has high accuracy in the diagnosis of PT, which can provide important evidence for the differentiation of benign and malignant PT, and then assist in the clinical selection of individualized surgical programs.

Abstract: Pleomorphic adenoma is the most common parotid gland tumor and superficial parotidectomy with preservation of the facial nerve is the most common and appropriate treatment for most low-morbidity tumors.
