Salivary glands are sites for a great variety of tumors. The parotid gland is the most common site followed by the submandibular gland. The pleomorphic adenoma represents the 60-70% of all tumors involving the major salivary glands, while the submandibular gland is involved in 8% of cases. The pleomorphic adenoma of the submandibular gland is rare and can present difficulty in diagnosis. The heterogeneous histology, a possible malignant transformation, an incomplete capsule that can determine a recurrence, are the most important characteristics of pleomorphic adenoma. A complete surgical removal of the tumor is the treatment of choice. In the case presented, the mass showed an unusual vascularization and remarkable dimensions.
唾液腺是多种肿瘤的发生部位。腮腺是最常见的部位，其次是下颌下腺。多形性腺瘤占所有累及大唾液腺肿瘤的60% - 70%，而下颌下腺受累的病例占8%。下颌下腺多形性腺瘤较为罕见，诊断可能存在困难。组织学异质性、可能的恶性转化、可导致复发的不完整包膜，是多形性腺瘤的最重要特征。肿瘤的完整手术切除是首选治疗方法。在本病例中，肿块显示出异常的血管分布和较大的尺寸。
