Abstract

Warthin’s tumor is the second most common salivary gland benign tumor, typically occurring in the fifth to seventh decades of life which shows an indolent feature. It is usually found in the parotid gland but occasionally in extra-parotid locations such as peri-parotid lymph node. However, Report of solitary Warthin’s tumor in cervical lymph node is unusual. We here report a case of 72-year-old male with simultaneous malignant melanoma on eyelid and cervical lymph node enlargement in cervical level II area thus mimicking malignancy metastasis. After excisional biopsy under the local anesthesia, pathology was reported as papillary cystadenoma lymphomatosum, which is a histologically pathognomic finding of Warthin’s tumor. However, there was no suspicious tumorous lesion in major or minor salivary glands. This case suggests that Warthin’s tumor should be considered as a possible pathology in solitary lymph node lesion of neck.
