The lower lip is a very rare emerging site for pleomorphic adenoma. The present review is to accentuate the definition, frequency, clinical and histopathological features, differential diagnosis, prognosis, and treatment choices of pleomorphic adenoma. We reviewed the English-language literature addressing pleomorphic adenoma of the lower lip. The tumors of minor salivary glands are not frequent among whole salivary glands tumors. Pleomorphic adenoma is the most common neoplasm among the minor salivary glands. A wide excision is recommended if there is no cosmetic care and no risk of damage to the functional structures of head and neck. Malignancy of the minor salivary glands are not rare. In addition, malignant transformation of pleomorphic adenoma involved in the benign tumors of minor salivary glands are possible. Thus, awareness of the possibility of existence of a pleomorphic adenoma or a malignant tumor within a mass located on the lower lip has a mentionable importance.
下唇是多形性腺瘤非常罕见的发生部位。本综述旨在强调多形性腺瘤的定义、发病率、临床和组织病理学特征、鉴别诊断、预后及治疗选择。我们回顾了关于下唇多形性腺瘤的英文文献。小唾液腺肿瘤在整个唾液腺肿瘤中并不常见。多形性腺瘤是小唾液腺中最常见的肿瘤。如果不考虑美容因素且不存在对头颈部功能结构造成损伤的风险，建议进行广泛切除。小唾液腺恶性肿瘤并不罕见。此外，小唾液腺良性肿瘤中的多形性腺瘤有可能发生恶变。因此，意识到下唇肿物内存在多形性腺瘤或恶性肿瘤的可能性具有重要意义。
