Purpose
Recent reports indicate an increase in the prevalence of Warthin’s tumours (adenolymphoma) with percentages which exceed that of pleomorphic adenomas (PA) in the same registries. The purpose of this study is to analyse a large cohort of benign parotid tumours in relation to various demographic and other patients’ characteristics that might affect their incidence.
Methods
A retrospective review of prospective collected data was performed on all patients who have been operated for a parotid mass in the last 5 years. A total of 474 patients with benign lesion were included in the study. Age, gender, smoking status, histological diagnosis, site of lesion, and size of tumour were recorded.
Results
Warthin’s tumours were the most common benign lesions, found in 201 (42.4%) parotic glands followed by pleomorphic adenomas found in 138 (29.1%) of these surgical cases. Patients with WT had a mean age of 61.6 years instead of 52 years for PA patients (t = 6.589, p < 0.001). The vast majority (93%) of patients with WT had a current or previous history of smoking compared with 47% of PA patients (p = 0.001). There was a male predominance regarding WT with a male:female (M:F) ratio of 2.3:1, whereas the corresponding ratio of PA was 1:1.4.
Conclusions
This study confirms the increased regional prevalence of WT reported in studies mainly carried out in central Europe. This could affect future management of WT, which remains largely controversial due to the extremely low malignant potential reported, concurrently with its higher rates of multiplicity and recurrence, as well as the moderately accurate results of FNA biopsies.
