	'''Systemic scleroderma''', also known as '''systemic sclerosis''', is a chronic autoimmune disease characterized by [[fibrosis]] (thickening and hardening) of the skin and internal organs. It is a complex condition that affects the [[connective tissue]] and can lead to significant morbidity and mortality.		'''Systemic scleroderma''', also known as '''systemic sclerosis''', is a chronic autoimmune disease characterized by [[fibrosis]] (thickening and hardening) of the skin and internal organs. It is a complex condition that affects the [[connective tissue]] and can lead to significant morbidity and mortality.

	==Pathophysiology==		==Pathophysiology==
	Systemic scleroderma is primarily characterized by excessive [[collagen]] deposition in the skin and other organs. The exact cause of the disease is unknown, but it is believed to involve a combination of genetic, environmental, and immunological factors. The disease process involves [[autoimmunity]], [[vascular dysfunction]], and [[fibrosis]].

The disease process involves [[autoimmunity]], [[vascular dysfunction]], and [[fibrosis]].

	===Autoimmunity===		===Autoimmunity===
	In systemic scleroderma, the immune system mistakenly attacks the body's own tissues, leading to inflammation and fibrosis. [[Autoantibodies]] such as anti-centromere and anti-Scl-70 are often present in patients and can be used as markers for diagnosis.

	===Vascular Dysfunction===		===Vascular Dysfunction===
	Vascular abnormalities are a hallmark of systemic scleroderma. Patients often experience [[Raynaud's phenomenon]], which is characterized by episodic vasospasm of the fingers and toes. Over time, persistent vascular damage can lead to [[digital ulcers]] and [[pulmonary arterial hypertension]].		Vascular abnormalities are a hallmark of systemic scleroderma.

Over time, persistent vascular damage can lead to [[digital ulcers]] and [[pulmonary arterial hypertension]].

	===Fibrosis===		===Fibrosis===
	Fibrosis in systemic scleroderma results from the overproduction of collagen by [[fibroblasts]]. This leads to thickening and hardening of the skin and can affect internal organs such as the [[lungs]], [[heart]], [[kidneys]], and [[gastrointestinal tract]].

	The clinical presentation of systemic scleroderma is highly variable and can range from mild skin involvement to severe multi-organ disease.		The clinical presentation of systemic scleroderma is highly variable and can range from mild skin involvement to severe multi-organ disease.

	===Skin Involvement===		===Skin Involvement===
	The skin changes in systemic scleroderma typically begin with [[edema]] and progress to [[sclerosis]]. The skin becomes tight, shiny, and may restrict movement. [[Telangiectasia]] and [[calcinosis]] can also occur.		The skin changes in systemic scleroderma typically begin with [[edema]] and progress to [[sclerosis]].

	===Gastrointestinal Tract===		===Gastrointestinal Tract===
	The gastrointestinal tract can be affected at any level, leading to symptoms such as [[dysphagia]], [[gastroesophageal reflux disease]], and [[malabsorption]].

	===Renal Involvement===		===Renal Involvement===

	==Diagnosis==		==Diagnosis==
	Diagnosis of systemic scleroderma is based on clinical features, laboratory tests, and imaging studies. The presence of specific autoantibodies can aid in diagnosis. [[Skin biopsy]] may be performed to confirm the diagnosis.		Diagnosis of systemic scleroderma is based on clinical features, laboratory tests, and imaging studies.

	==Treatment==		==Treatment==
	There is no cure for systemic scleroderma, but treatment focuses on managing symptoms and preventing complications. [[Immunosuppressive therapy]], [[vasodilators]], and [[antifibrotic agents]] are commonly used. Physical therapy and occupational therapy can help maintain mobility and function.
