Warthin tumor is a comparatively rare benign epithelial tumor of the salivary gland, which most frequently arises in the parotid gland.
We report a rare case of Warthin tumor involving the bilateral parotid glands, which occurred 9 years after an initial operation on a right parotid Warthin tumor.
The patient was a 69-year-old man who complained of bilateral parotid swelling. The clinical diagnosis was Warthin tumor of the bilateral parotid gland, and the tumors were surgically removed.
The left tumor measured 32×18×17mm, the right tumor, 22×20×18mm.
Histopathological findings were composed of lymphoid tissues with germinal centers and papillaly growth of epithelial elements. The histopathological diagnosis was bilateral Warthin tumors of the parotid glands.
99mTcO4- scintigraphy, 67Ga citrate scintigraphy, computed tomography, and ultrasoundsonography were useful to detect Warthin tumor in our case.
