elastosis
elastosis[i‚la′stō·səs] (medicine) Retrogressive change in elastic tissue. Retrogressive change in cutaneous connective tissue resulting in excessive amounts of material which give the staining reactions for elastin. elastosis
elastosis [e″las-to´sis] 1. degeneration of elastic tissue.2. degenerative changes in the dermal connective tissue with increased amounts of elastotic material.3. any disturbance of the dermal connective tissue.actinic elastosis premature aging of the skin due to prolonged exposure to sunlight, seen especially in light-skinned persons, characterized by inelasticity, thinning or sometimes thickening, wrinkling, dryness with fine scaling, and variable hyperpigmentation, often with development of cherry angiomas, telangiectasis, senile lentigines, ecchymosis, milia, and senile keratosis. Called also senile or solar elastosis.nodular elastosis of Favre and Racouchot a type of actinic elastosis seen chiefly in elderly men, in which giant comedones, pilosebaceous cysts, and large folds of furrowed and yellowish skin are seen in the periorbital region; called also nodular elastoidosis.elastosis perfo´rans serpigino´sa (perforating elastosis) an elastic tissue defect, occurring alone or in association with other disorders, including Down's syndrome and Ehlers-Danlos syndrome, in which elastomas are extruded through small keratotic papules in the epidermis; the lesions are usually arranged in arc-shaped, continuous clusters on the sides of the nape, face, or arms.senile elastosis (solar elastosis) actinic elastosis.e·las·to·sis (ē'las-tō'sis), 1. Degenerative change in elastic tissue. 2. Degeneration of collagen fibers, with altered staining properties resembling elastic tissue. Synonym(s): elastoid degeneration (1) , elastotic degeneratione·las·to·sis (ĕ-las-tō'sis) 1. Degenerative change in elastic tissue. 2. Degeneration of collagen fibers, with altered staining properties resembling elastic tissue, or formation by fibroblast-activated ultraviolet or mast cell mediators of abnormal fibers.
Synonym(s): elastoid degeneration (1) , elastotic degeneration. elastosis 1. Increase in elastin in a tissue. 2. Degeneration and breakup of the elastic fibres of connective tissue. The condition often affects the skin as a result of ultraviolet irradiation. e·las·to·sis (ĕ-las-tō'sis) 1. Degenerative change in elastic tissue. 2. Degeneration of collagen fibers, with altered staining properties resembling elastic tissue. elastosis
