• Chromhidrosis, colored sweat.
• Epidermolysis bullosa, a connective tissue disorder that causes fragile skin that blisters and tears easily.
• Harlequin ichthyosis, thick, hard patches or plates on the skin that are present at birth.
• Lamellar ichthyosis, waxy skin layer that sheds in the first few weeks of life, revealing scaly, red skin.
• Necrobiosis lipoidica, rash on the lower legs that can develop into ulcers (sores).
