Morphea is a form of scleroderma, a term that literally means "hard skin." Signs of morphea include:

  • Hardening and thickening of the skin.
  • Discoloration of the affected skin to look lighter or darker than the surrounding area.
  • Oval-shaped patches that may change colors and gradually develop a whitish center.
  • Linear patches, especially when on arms and legs
  • Loss of hair and sweat glands in the affected area over time.

Morphea usually affects only the uppermost layers of your skin (the dermis and the superficial fatty tissue beneath the dermis). In some cases, morphea may involve the deeper fatty tissue or the connective tissue (fascia or muscle) below your skin. The condition generally lasts several years and then disappears on its own. However, it usually leaves patches of darkened or discolored skin.

When to see a doctor

If you notice patches of discoloring, hardening or thickening skin, see your doctor. Early diagnosis and treatment may help slow the development of new patches, and allow your doctor to identify and treat complications before they worsen.
