Morphea is a rare skin condition characterized by localized patches of hardened, discolored skin. It occurs when collagen builds up in the skin, leading to thickening and a shiny appearance. The exact cause of morphea is not well understood, but it may involve immune system dysfunction or environmental factors. The condition can affect people of all ages but is most commonly seen in adults. Morphea typically does not cause pain or itching, but it can lead to cosmetic concerns. Treatment options may include topical medications, phototherapy, or systemic therapies to help manage symptoms and improve skin appearance.
