Lichen sclerosus, an inflammatory skin disease that most often affects the vulva and the penis. Multiple sclerosis, or focal sclerosis, [2] is a central nervous system disease which affects coordination. Osteosclerosis, a condition where the bone density is significantly increased, resulting in decreased lucency on radiographs.
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.
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 ...
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.
Several synapomorphies support this hypothesis, such as the presence of: sclerotic ossicles, paired pectoral fins, a dermal skeleton with three layers (a basal layer of isopedin, a middle layer of spongy bone, and a superficial layer of dentin), and perichondral bone.

Dementia is a devastating condition that impacts up to 10 percent of older adults. And while there's no cure, getting diagnosed early can help patients get on a treatment plan and families prepare ...
Atypical scleroderma may show any variation of these changes without skin changes or with finger swelling only. [ 28 ] 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).
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.
