Warthin tumor is the second most common benign tumor of salivary glands. Here we present an interesting case of squamous cell carcinoma arising from the Warthin tumor in the cervical lymph node. The patient had another Warthin tumor in the parotid gland as well. Both the malignant transformation of Warthin tumor and the heterotopic occurrence of Warthin tumor in the cervical lymph node are rare. This exceptionally rare case demonstrates that the 2 rare clinical entities can occur simultaneously and affect clinical decisions.
