Aim: This report shows an incidental finding of Warthin tumor in upper lip mucosa during hospitalization for a biting lesion of cheek mucosa MATERIALS AND METHODS: A 32-year-old male affected by a biting lesion of cheek mucosa was presented at Maxillo- Facial Unit of Federico II University. Clinical examination showed as an incidental finding a solid mass in the superficial layer of upper lip mucosa. We performed mini-invasive surgical treatment to obtain a radical excision of the cheek lesion at the same time as excision of Warthin tumor.
Results: a follow up of 12 months was performed. The complete healing of the two wounds was achieved, with no recurrence of any of the pathologies.
Discussion: The location of this Warthin tumor of minor salivary glands is very unusual. The role of imaging in diagnosis of Warthin tumor of minor salivary glands is to define localization, shape and dimension, contour, malignant features, nodal involvement. The role of fine needle aspiration cytology (FNAC) is critical in the diagnosis and therapy of minor salivary gland tumors. The surgical treatment in patients affected by Warthin tumour of minor salivary glands is local excision with a wide tumor free margin to prevent potential recurrence.
Conclusions: Warthin tumor of minor salivary glands is a rare disease. We report a singular case of Warthin tumor localized in the upper lip mucosa, found as an incidental finding during a recovery for a biting lesion of cheek mucosa.
Key words: Incidental finding, Minor salivary glands, Warthin tumor.
Presentiamo un caso di Tumore di Warthin delle ghiandole salivari minori in un maschio adulto caucasico affetto da una lesione da masticamento della mucosa della guancia. L’esame clinico mostrava un riscontro accidentale di una massa solida situata nello strato superficiale della mucosa del labbro superiore. L’esame ecografico ha evidenziato una massa solida ipoecogena ben definita di circa 3x4 cm. Abbiamo eseguito un trattamento chirurgico mini-invasivo nel febbraio 2015 per ottenere una escissione radicale della lesione guancia e contemporaneamente del tumore di Warthin del labbro superiore senza recidiva della patologia.
