Background Warthin’s tumor or cystadenolymphoma (CAL) is a benign salivary gland tumor occurring almost exclusively in the parotid gland. CALs of other locations are rare.
Case presentation We report a laryngeal CAL detected in a positron emission tomography/computed tomography (PET/CT) performed for breast cancer follow-up. The tumor was successfully treated by transoral surgery.
Discussion Only 14 cases of laryngeal CAL are reported worldwide. These cases confirmed our experience of an uncomplicated and mostly successful transoral resection.
Conclusion CALs of the larynx are very rare. They are characterized by hypermetabolism in PET/CT. The increasing use of PET/CT investigations in cancer patients could give rise to more incidental findings of CALs at unusual locations such as the larynx.
