Abstract
The eosinophilic adenoma (so-called “oncocytoma”) mainly arises in salivary gland such as parotid gland and submandibular gland, but proportion occupied for all salivary gland neoplasm is 1% or less and very rare disease. We herein describe a 57-year-old woman who presented with a mass in the parotid gland, and after the surgical resection of the parotid gland, the prognosis is good for 16 months. Oncocytoma is benign tumor, but have been reported the malignant change in some cases, so therefore a long-term observation for recurrence is necessary.
