We report a case of pleomorphic adenoma of the palate associated with squamous cell carcinoma of the superficial mucosa.<BR>The patient was a 50-year-old man. On presentation, a 17×20-mm, painless, elastic hard tumor with a clear border was seen on the right side of the palate, accompanied by an ulcer measuring 3-mm in diameter. To avoid effects on diagnosis, biopsy was done avoiding the ulcer with inflammatory reaction. A pleomorphic adenoma was diagnosed. The tumor was excised under the diagnosis of a benign tumor. The pathological diagnosis was a pleomorphic adenoma. However, squamous cell carcinoma was confirmed in the oral mucosal epithelium covering the tumor. These two tumors were not connected.
