What is progressive systemic sclerosis also known as?

Progressive systemic sclerosis is indeed commonly known as scleroderma. This condition is characterized by the hardening and tightening of the skin and connective tissues due to an overproduction of collagen, which can lead to severe complications affecting internal organs. The terminology "systemic sclerosis" highlights that it can affect the whole body, not just the skin.

This condition is distinct from arthritis, which specifically refers to inflammation of the joints, and fibromyalgia, recognized for widespread pain and tenderness without inflammation. Rheumatoid arthritis is an autoimmune disorder primarily affecting the joints, differing in pathophysiology and presentation from scleroderma. Understanding these distinctions is crucial for recognizing the various musculoskeletal and systemic conditions and their management.
