原发性乳腺血管肉瘤的诊治进展

原发性乳腺血管肉瘤是一种极为罕见的恶性肿瘤,发病率约为所有乳腺恶件肿瘤的0.05%.其内皮细胞,血管及核分裂等的异型性是区别于其他乳腺肿瘤的特征.CD31、CD34、抗FⅧ受体等内皮细胞标志物及VEGF在该病组织标本中阳性表达率较高.除细针穿刺活检外,超声、钼靶及MRI可能对诊断有一定的帮助.手术治疗是治疗该病的首选,放化疗及分子靶向治疗的作用仍在研究中.

Progress of primary angiosarcoma of breast

Primary angiosarcoma of breast is a rare malignant tumor,about 0.05%of all the malignant tumor of breast.The heteromorphism,such as endothelioeyte,blood vessel even caryocinesia,distinguishes this disease from other carcinoma of breast.Positive ratio of endothelial cell makers(Anti-FⅧR,CD3 1,CD34,UEA-1,et al)and VEGF is relatively high.Besides fine needle aspiration and biopsy,ultrasound,X-ray and MRI maybe helpful to di agnosis.Surgery is certainly the first choice to care this disease.The effect of chemotherapy,radiotherapy and tar geted therapy is still in research.
