By Mayo Clinic staff- Impetigo. The open sores and fissures that can occur with dermatitis may become infected. A mild form of infection is impetigo, usually due to staphylococci bacteria. Having atopic dermatitis predisposes you to this infection.
- Cellulitis. If you notice red streaks on your skin, you may have cellulitis, a bacterial infection of tissues under the skin. Cellulitis appears as intensely inflamed skin that's swollen, red, tender and warm to the touch, with spreading, indistinct margins. Cellulitis that occurs in someone whose immune system is compromised is potentially life-threatening. See your doctor as soon as possible if you think you have cellulitis.
Scarring and changes in skin color are other potential complications from dermatitis.
