Abstract
Pleomorphic adenoma is the most common tumor of the salivary gland. It occurs most frequently in the major salivary glands, especially in the parotid glands. In the minor salivary glands, it occurs most commonly in the palate and relatively uncommon in the upper lip. We reported three cases of pleomorphic adenoma of the upper lip. They were well-demarcated and movable and could be easily resected under local anesthesia. No recurrence has been noted. They were pathologically diagnosed as pleomorphic adenoma.
In Japanese literature, 39 cases (4.2 %) of 919 minor salivary gland tumors were pleomor-phic adenoma of the lip.
It is considered necessary to set a safety margin for postoperative deformity and dysfunction of the lip.
