作者复习了加利福尼亚大学洛杉机医院从1956至1974年114例涎腺混合瘤住院病人的临床资料和组织学切片,其中除去两例具有不典型的形态特征、破坏性浸润和转移的恶性混合瘤,其余112例形态学良性、周界清楚,有完整或不完整的包膜,没有破坏性浸润,认为属良性混合瘤。其中女性患者71例(63%),男性患者41例(37%),就诊年龄女性患者从13至81岁,平均45岁;男性从11岁至79岁,平均43岁。作者探讨了112例非恶性混合瘤的形态、细胞丰富程度、间质包膜结构及淋巴细胞浸润以及外科手术方式和肿瘤复发间的关系如下: (一)生长方式:研究结果表明,涎腺肿瘤有其独特的生长方式,肿瘤在一至多处显
The authors reviewed clinical data and histological sections of 114 patients with mixed parotid tumors from 1956 to 1974 at the University of California Los Angeles, Los Angeles, where two malignant mixed tumors with atypical morphological features, destructive infiltration, and metastases were removed. The remaining 112 patients were benign in morphology, well-circumscribed, with complete or incomplete capsules, and had no destructive infiltration, suggesting a benign mixed tumor. Of these, 71 were female (63%), 41 were male (37%), and females aged 13 to 81 years of age at the treatment age were 45 years old. Males ranged from 11 to 79 years old with an average age of 43. The authors explored the relationship among the morphology, cell richness, interstitial envelope structure, and lymphocyte infiltration of 112 non-malignant mixed tumors, and the relationship between surgical methods and tumor recurrence as follows: (1) Growth patterns: Results of the study showed that the tumors of parotid glands With its unique growth pattern, tumors appear in one or more places
