Abstract:
We report a case of an oncocytic lipoadenoma of the submandibular gland, which is a very rare benign tumor of the salivary gland. The patient was a 36-year-old man with a right submandibular mass measuring 29 × 1.3 × 1.2 cm. When the preoperative diagnostic tools were insufficient to rule out malignancy and for definite diagnosis, total removal of the gland was performed. Histopathologically, microscopic examination revealed a well-circumscribed tumor that is surrounded by a thin, fibrous capsule. The majority of the tumor consisted of adipocytes and normal components of salivary gland tissue. Oncocytic cells were observed only focally. Physicians should keep in mind that salivary glands may rarely exhibit this special tumor growth pattern.
