Pleomorphic adenoma of the upper lip: report of two cases.

Pleomorphic adenoma is the commonest neoplasm of the salivary gland. It occurred most frequently in the major salivary glands, especially in the parotid glands. In the minor salivary glands, it occurred most commcnly in the palate, and relatively uncommon in the upper lip. We described two cases of the pleomorphic adenoma occurred in the upper lip. The two females were referred to our ward because of tumorous lesions in their upper lips. The tumors were well-demarcated and movable, and could be easily resected under local anesthesia. No recurrence was noted. Histologically, they were pleomorphic adenomas showing epithelial predominant pattern, which is one of the four types subclassified previously.
