Images of Note: Cutaneous Manifestations of Systemic Sclerosis
Here’s stark visual evidence of why skin thickness may be the most debilitating aspect of a condition whose name comes from the Greek for “hard skin.”

Systemic sclerosis (SSc) is also known as scleroderma, which is derived from the Greek skleros (“hard”) and derma (“skin”). As the nomenclature implies, skin thickening is a considerably debilitating characteristic of this condition, especially in diffuse disease
The skin changes of SSc usually start with an early phase of skin edema, manifested as swollen fingers, hands and feet. In diffuse disease, these changes are soon followed by development of firm, thickened skin over the extremities, trunk and face. This thickening can lead to skin tethering and flexion contractures of joints (center image below).
Apart from skin thickening, other cutaneous manifestations of SSc include Raynaud phenomenon (top left image, showing the cyanotic phase of Raynaud phenomenon), ischemic digital ulcers (bottom left image) and ulcers over the extensor aspects of the metacarpophalangeal and interphalangeal joints, resulting from repeated microtrauma (center image).
Other features include pruritus, progressive cutaneous telangiectasias (top right image), calcinosis cutis (bottom right image), hyper and/ or hypopigmentation, and alopecia and skin dryness from loss of eccrine sweat glands and pilosebaceous units.
