What it means: The fronts of the legs along the shins tend to bang and bump into things a lot. For someone with diabetes, the damage to the capillaries and small blood vessels that are characteristic of the disease will cause them to leak when traumatized, leading to brown discoloration known as diabetic dermopathy.

More clues: The brownish patches may also be rough, almost scaly (although they don't open up), and tend to form ovals or circles. They don't hurt. Another common skin change of diabetes to look for: An open, unhealed sore on the foot. Diabetics lose the perception of pain, temperature, and touch on their feet, making them unlikely to notice common foot blisters -- which then go untreated and may become infected.

What to do: There's no health danger from diabetic dermopathy, and no need for treatment. But if someone who hasn't been diagnosed with diabetes shows these signs, it's worth checking for other signs of diabetes, such as thirst, excessive urination, tiredness, or blurry vision.
