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.
Atypical scleroderma may show any variation of these changes without skin changes or with finger swelling only. [ 27 ] Laboratory testing can show antitopoisomerase antibodies , like anti-scl70 (causing a diffuse systemic form), or anticentromere antibodies (causing a limited systemic form and the CREST syndrome).
CREST syndrome, also known as the limited cutaneous form of systemic sclerosis (lcSSc), is a multisystem connective tissue disorder. The acronym "CREST" refers to the five main features: calcinosis , Raynaud's phenomenon , esophageal dysmotility , sclerodactyly , and telangiectasia .
Hippocampal sclerosis (HS) or mesial temporal sclerosis (MTS) is a neuropathological condition with severe neuronal cell loss and gliosis in the hippocampus. [1] Neuroimaging tests such as magnetic resonance imaging (MRI) and positron emission tomography (PET) may identify individuals with hippocampal sclerosis. [ 2 ]

Such lesions give rise to extensive astrocyte loss, which may occur in part in the absence of any other tissue injury, such as demyelination or axonal degeneration (lesion type 5). Finally, lesions with a variable degree of astrocyte clasmatodendrosis are found, which show plaque-like primary demyelination that is associated with ...
Pain: acute pain is mainly due to optic neuritis (with corticosteroids being the best treatment available), as well as trigeminal neuralgia, Lhermitte's sign, or dysesthesias. [154] Subacute pain is usually secondary to the disease and can be a consequence of spending too long in the same position, urinary retention, and infected skin ulcers ...
