Dermasclerosis, also known as scleroderma, is a rare autoimmune disease characterized by the hardening and tightening of the skin and connective tissues. It occurs due to overproduction of collagen, leading to fibrosis and changes in the skin's texture and appearance. The condition can be localized or systemic, affecting other organs such as the lungs, heart, and digestive tract. Symptoms may include skin thickening, Raynaud's phenomenon, and joint pain, with treatment focusing on symptom management and improving quality of life.
