The cause of lymphangiosarcoma is not known. It appears as one or more bluish- red bumps on the affected arm or leg. First, one purple-red, slightly raised area in the skin of the arm or leg appears. The patient usually describes it as a bruise. Later, more tumors appear, and the bumps grow.
Death usually results from metastases to the lungs.
