淋巴管肉瘤（ｌｙｍｐｈａｎｇｉｏｓａｒｃｏｍａ）起源于淋巴管的内皮细胞，其病理形态难与血管内皮肉瘤鉴别，因此两者统称脉管肉瘤（ａｎｇｉｏｓａｒｃｏｍａ）。淋巴管肉瘤常见于乳腺癌根治术后的患侧上肢，与淋巴水肿有关，也可见于其它原因引起淋巴回流障碍的肢体... Lymphosomasarcoma originates from the lymphatic endothelial cells. Its pathological morphology is difficult to distinguish from vascular endothelial sarcoma. Therefore, both are collectively called angiosarcoma. Lymphangiole of sarcoma is common in the upper limbs of the affected side after radical mastectomy. It is associated with lymphedema and can also be found in limbs with other causes of lymphatic drainage disorders.
