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.
Multiple sclerosis is an autoimmune disease, primarily mediated by T-cells. [15] The three main characteristics of MS are the formation of lesions in the central nervous system (also called plaques), inflammation, and the destruction of myelin sheaths of neurons.
Pansclerotic morphea is manifested by sclerosis of the dermis, panniculus, fascia, muscle, and at times, the bone, all causing disabling limitation of motion of joints. [ 3 ] : 171 Linear scleroderma is a type of localised scleroderma [ 11 ] which is an autoimmune disease characterized by a line of thickened skin which can affect the bones and ...
Osteosclerosis is a disorder characterized by abnormal hardening of bone and an elevation in bone density. It may predominantly affect the medullary portion and/or cortex of bone.
Tuberous sclerosis complex (TSC) is a rare multisystem autosomal dominant genetic disease that causes non-cancerous tumours to grow in the brain and on other vital organs such as the kidneys, heart, liver, eyes, lungs and skin.
Lipodermatosclerosis is most commonly diagnosed in middle-aged women. [ 3 ] The origin of lipodermatosclerosis is probably multifactorial, involving tissue hypoxia, leakage of proteins into the interstitium, and leukocyte activation.
Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process.
Normally MS lesions are small ovoid lesions, less than 2 cm. long, oriented perpendicular to the long axis of the brain's ventricles [18] Often they are disposed surrounding a vein [19] Demyelinization by MS. The Klüver-Barrera colored tissue show a clear decoloration in the area of the lesion (Original scale 1:100)
