作者检查584例原发性腮腺肿瘤和瘤样病变。其中原发性腮腺良性血管瘤29例(占4.9％),可分为海绵状血管瘤20例,良性血管内皮细胞瘤9例,后者年龄都在12个月以下,全是女性位于右侧。组织学上良性血管内皮细胞瘤表现为一致的生长方式,每个小叶部分表现完全相同。肿瘤的血管腔为扁平内皮细胞衬里,偶而混杂若干核轻度非典型的肥胖细胞(PlumpCell),稍大于其他内皮细胞,突入管腔内。 The authors examined 584 primary parotid gland tumors and tumor-like lesions. Among them, 29 cases (4.9%) of primary parotid benign hemangiomas can be divided into 20 cases of cavernous hemangioma and 9 cases of benign vascular endothelial cell tumors. The latter are all under 12 months of age, and all women are located on the right side. . Histologically, benign vascular endothelial cell tumors showed a consistent growth pattern, and each lobular portion showed exactly the same. The vascular lumen of the tumor is lined with flat endothelial cells, occasionally mixed with several nuclear non-typical fat cells (PlumpCell), slightly larger than other endothelial cells and protruding into the lumen.
