What is schleroderma?

Scleroderma is accurately identified as an autoimmune disease that leads to the thickening and tightening of the skin, as well as potentially affecting internal organs. In this condition, the body's immune system mistakenly attacks its own tissues, resulting in increased collagen production, which is responsible for the skin's firmness and elasticity. The skin can become hard and restricted, impacting mobility and comfort. This disease can also cause complications within the body, including issues with the lungs, heart, and digestive system, making it more than just a skin condition.

Understanding scleroderma's nature as an autoimmune disorder is crucial in distinguishing it from contagious infections, malignancies, or simple inflammatory conditions, which are indicated in the other options. This context helps clarify that it is a chronic condition requiring specialized attention and management.
