Poorly-managed diabetes can result in a patient developing eruptive xanthomatosis, warns the American Diabetes Association. It appears as firm, yellow, round bumps in the skin ringed in red.

This skin infection usually appears in men with Type 1 diabetes who have high cholesterol levels and is treated by bringing down blood sugar levels.
