| elastoid degeneration | 1. Degenerative change in elastic tissue. 2. Degeneration of collagen fibres, with altered staining properties resembling elastic tissue, or formation by fibroblast-activated ultraviolet or mast cell mediators of abnormal fibres. Synonym: elastoid degeneration, elastotic degeneration. (05 Mar 2000) |

| elastoma | A tumour-like deposit of elastic tissue. (05 Mar 2000) |
| elastometer | A device for measuring the elasticity of any body or of the animal tissues. (05 Mar 2000) |

| elastonectin | <protein> Elastin binding protein (120 kD) found in extracellular matrix, produced by skin fibroblasts. (18 Nov 1997) |
| elastorrhexis | Fragmentation of elastic tissue in which the normal wavy strands appear shredded and clumped, and take a basophilic stain. Origin: G. Rhexis, rupture (05 Mar 2000) |
| elastosis | 1. Degenerative change in elastic tissue. 2. Degeneration of collagen fibres, with altered staining properties resembling elastic tissue, or formation by fibroblast-activated ultraviolet or mast cell mediators of abnormal fibres.

| elastosis colloidalis conglomerata | Yellow papules developing in sun-damaged skin of the head and backs of the hands, composed of colloid material in the dermis resembling amyloid but with a different ultrastructure. Synonym: colloid acne, colloid pseudomilium, elastosis colloidalis conglomerata. Origin: L. Milium, millet (05 Mar 2000) |
| elastosis dystrophica | Tiny breaks in the elastin-filled tissue in the back of the eye (retinae). These abnormalities are visible to the doctor during an examination using a viewing instrument called an ophthalmoscope. Angioid streaks are seen in patients with pseudoxanthoma elasticum (abbreviated PXE), a rare disorder of degeneration of the elastic fibres with tiny areas of calcification in the skin, back of the eyes (retinae), and blood vessels. Angioid streaks can be associated with blindness. (12 Dec 1998) |
| elastosis perforans serpiginosa | Circinate groups of asymptomatic keratotic papules; the epidermis is thickened around a central plug of dermal elastic tissue which is extruded through the epidermis. (05 Mar 2000) |
| elastotic degeneration | 1. Degenerative change in elastic tissue. 2. Degeneration of collagen fibres, with altered staining properties resembling elastic tissue, or formation by fibroblast-activated ultraviolet or mast cell mediators of abnormal fibres. Synonym: elastoid degeneration, elastotic degeneration. (05 Mar 2000) |
