What is often one of the earliest signs in cases of scleroderma?

Raynaud phenomenon is often one of the earliest signs of scleroderma and is characterized by episodic changes in color, temperature, and sensation in the fingers and toes in response to cold or stress. This condition occurs due to vasospasm of the small blood vessels, leading to a decreased blood flow. In scleroderma, which involves progressive fibrosis and vascular abnormalities, the presence of Raynaud phenomenon serves as an important early indicator.

Many patients with scleroderma experience Raynaud phenomenon before the onset of more definitive symptoms related to skin, joints, and internal organs, making it a critical sign that may prompt further evaluation for this autoimmune disorder.

While joint pain, skin rashes, and hair loss can occur in scleroderma, they typically appear later in the disease process. Therefore, identifying Raynaud phenomenon early can facilitate timely diagnosis and management of scleroderma.
