Abstract


Oncocytic lipoadenoma is a rare salivary gland tumor composed of adipose tissue and oncocytic epithelial cells in varied proportions. We report a case of an oncocytic lipoadenoma of the submandibular gland, which presented as a submandibular gland mass. The patient was a 65-year-old woman with a right submandibular mass measuring 2 x 2 x 1.6 cm. As a sonographic evaluation and computed tomograph scan gave us the impression of benign submandibular gland tumor such as pleomorphic adenoma, we resected the right side submandibular gland. Grossly, the tumor was well circumscribed with yellow to brown cut surface. Microscopically, the tumor was surrounded by a thin, fibrous capsule and composed of oncocytic epithelial cells admixed with mature adipose tissue. Final diagnosis was an oncocytic lipoadenoma. We discussed here radiologic and pathologic finding of this rare salivary gland tumor.
