A Case of Pleomorphic Adenoma of the Sublingual Gland

Abstract

Pleomorphic adenoma is the most common tumor arising in salivary glands. However, pleomorphic adenoma of the sublingual gland is extremely rare. Furthermore, sublingual tumor is difficult to diagnose, because the most cases are malignant. We report on a man with pleomorphic adenoma of the sublingual gland. His chief complaint was a mass in the left side of oral floor. The patient underwent removal of the tumor. The pathologic diagnosis was pleomorphic adenoma. There has been no evidence of recurrence for one and a half years after the operation. It is necessary to treat as malignancy, if the sublingual tumor is suspected.
