Abstract

IntroductionWarthin tumors are the second most common benign tumors of the parotid gland. We examined the clinical features of Warthin tumors in our hospital, and analyzed the consistency within the literatures. ObjectiveThe aim of this study is to analyze the clinical features of Warthin tumors in our 10-year experience of 118 Warthin tumors undergoing surgery at a single institute. MethodsFrom December 2006 to December 2016, 110 patients who underwent surgical treatment for Warthin tumors were identified based on their medical records. ResultsA total of 118 parotid gland operations were performed in 110 patients. Almost 90% of Warthin tumors were found in males, and average patient age was 66.1±6.1 years. The prevalence of smoking history was 89.1% (98/110). Eight patients (7.3%) had bilateral Warthin tumors. Seventy-seven lesions (65.3%) were located in the parotid tail portion, followed by 34 lesions in the superficial lobe (28.8%) and 7 lesions in the deep lobe (5.9%). ConclusionWe determined the appropriate extent of surgery depending on the fine needle aspiration cytology and tumor location by computed tomography scans. Partial facial dysfunction after the operation was detected in 12 cases, and facial nerve function recovered within 3 months. Only one patient experienced a recurrence, and was disease free after the re-operation. We suggest that our treatment algorithm, depending on the location of tumors and the result of fine needle aspiration cytology, can be useful to determine the appropriate extent of surgery for Warthin tumors.

Highlights

Warthin tumors are the second most common benign tumors of the parotid gland, accounting for about 15% of all parotid tumors.1---5 Warthin tumors typically present as an asymptomatic, slowly growing mass, usually located in the tail portion of the parotid gland.[1,2,5,6] Warthin tumors occur more frequently in males, with a peak incidence in the 5th and 6th decades
We examined the clinical features of Warthin tumors in patients treated in our hospital, and analyzed the consistency within the relevant literature
One hundred ten patients who received surgical treatment for Warthin tumor of the parotid gland were identified based on their medical records

Summary

Introduction

Warthin tumors are the second most common benign tumors of the parotid gland, accounting for about 15% of all parotid tumors.1---5 Warthin tumors typically present as an asymptomatic, slowly growing mass, usually located in the tail (inferior) portion of the parotid gland.[1,2,5,6] Warthin tumors occur more frequently in males, with a peak incidence in the 5th and 6th decades. Warthin tumors typically present as an asymptomatic, slowly growing mass, usually located in the tail (inferior) portion of the parotid gland.[1,2,5,6] Warthin tumors occur more frequently in males, with a peak incidence in the 5th and 6th decades. These tumors have a tendency toward multiplicity and bilaterality, and have an association with smoking.1---6. Many reports have presented patients with clinical features that differ from the traditional tumors in some way, such as increasing incidence among females, higher rates of tumor multiplicity and bilaterality.4---6.
