颌下腺混合瘤又名多形性腺瘤,是口腔涎腺组织中最常发生的肿瘤。但颌下腺混合瘤术后瘤细胞播散种植则极少见。我科于1976年～1987年收治2例。 [例1] 患者李某,女,22岁,住院号76—2645。于1971年发现左颌下一无痛性肿物至1974年如鸡卵大,曾在当地医院手术摘除,摘除肿物剖开为豆渣样。1976年再次复发,肿物如鸡卵大,经抗炎治疗无效。于1976年5月以左颌下腺混合瘤,不除外恶变收入院。系统检查未见异常。口腔颌面部检查:左颌下偏后可见一肿物约4×3×3Cm,质硬,分叶状,无压痛,活动度差,与周围组织粘连。左颌下腺导管口无红肿。
Submandibular gland mixed tumor, also known as pleomorphic adenoma, is the most common tumor in the oral parotid gland. However, it is rare to see tumor cells spread after implantation of mixed submandibular gland tumors. Our department was admitted to 2 cases from 1976 to 1987. [Example 1] Patient Li, female, 22 years old, hospital number 76-2645. In 1971, a painless mass was found in the left mandibular tract until 1974. For example, chicken eggs were large. They were surgically removed at a local hospital. The excised tumors were sectioned into bean dregs. In 1976, she relapsed again. Her masses, such as chicken eggs, were ineffective after anti-inflammatory treatment. In May 1976, mixed tumors with the left submandibular gland were not excluded from the Malignant Income Hospital. No abnormal system check. Oral and Maxillofacial Examinations: A mass of approximately 4 × 3 × 3 cm was seen retrospectively to the left submandibular area. The mass was hard, lobulated, no tenderness, poor mobility, and adhesion to the surrounding tissue. Left submandibular gland duct mouth without redness.
