Superficial thrombophlebitis

This is an unusual condition caused by spontaneous clotting of the blood in one of the veins lying under the skin of the breast.

It causes a tender cord to form under the skin and can also cause a distinctive linear dimpling of the skin along the course of the vein. It is also called Mondor's disease after one of the first doctors to describe the condition.

Other causes for skin changes including breast cancer must of course be excluded.

Once the diagnosis is made treatment consists of reassurance and explanation.

If the area is tender simple painkillers or anti-inflammatory medication may help. The lumpy area and dimpling usually resolve within a couple of weeks.
