Systemic scleroderma, or systemic sclerosis, is an autoimmune rheumatic disease characterised by excessive production and accumulation of collagen, called fibrosis, in the skin and internal organs and by injuries to small arteries. There are two major subgroups of systemic sclerosis based on the extent of skin involvement: limited and diffuse ...
Sclerosis (from Ancient Greek σκληρός (sklērós) 'hard') is the stiffening of a tissue or anatomical feature, usually caused by a replacement of the normal organ-specific tissue with connective tissue. The structure may be said to have undergone sclerotic changes or display sclerotic lesions, which refers to the process of sclerosis.
Morphea is a form of scleroderma that mainly involves isolated patches of hardened skin on the face, hands, and feet, or anywhere else on the body, usually with no internal organ involvement. [1] However, in Deep Morphea inflammation and sclerosis can be found in the deep dermis , panniculus , fascia , superficial muscle and bone.
Scleroderma is a group of autoimmune diseases that may result in changes to the skin, blood vessels, muscles, and internal organs. [2] [6] [8] The disease can be either localized to the skin or involve other organs, as well. [2]
Balo concentric sclerosis, an unusual presentation of plaques forming concentric circles, which can sometimes get better spontaneously. Schilder disease or diffuse myelinoclastic sclerosis: is a rare disease that presents clinically as a pseudotumoural demyelinating lesion; and is more common in children. [7] [8]
Mild skin reactions usually do not impede treatment whereas necroses appear in around 5% of patients and lead to the discontinuation of the therapy. [58] Also over time, a visible dent at the injection site due to the local destruction of fat tissue, known as lipoatrophy, may develop. [58]
Medlar bodies, also known as sclerotic or muriform cells, are thick-walled cells (5–12 microns) with multiple internal transverse septa or chambers that resemble copper pennies. When present in skin or subcutaneous tissue , the cells are indicative of chromoblastomycosis .
Drawing of sclerotic lesions from Babinski's thesis "Etude anatomique et clinique de la sclérose en plaques", 1885. Multiple sclerosis (MS) can be pathologically defined as the presence of distributed glial scars in the central nervous system that must show dissemination in time (DIT) and in space (DIS) to be considered MS lesions.
