It is most commonly seen in the chronically swollen (edematous) arms of women who have had a mastectomy for breast cancer. A malignant neoplasm that develops from the endothelial lining of lymphatics.  

A surgical operation to make artificial lymph channels. Establishment of artificial lymph ducts to bypass areas of blocked lymphatic circulation. The formation of artificial lymphatics or the use of microsurgical technique to reestablish lymphatic or lymphogenous continuity.  

A benign tumour formed of lymph tissues. Benign tumor made up of dilated lymph vessels. A benign (not cancerous) tumor in the skin composed of dilated lymph vessels. Lymphangiomas primarily occur on the arms and chest. They are usually removed by excision (cutting away the tumor) for cosmetic reasons. A localized collection of distended lymphatic…
