DefinitionThis section has been translated automatically.
Clinical and histological term for a congenital or acquired degeneration of the collagenous connective tissue in the corium. The elastotic material (see Elastosis actinica) behaves "staining technically" like the elastic fibres of the skin (hence the artificial name "elastotic").
EtiopathogenesisThis section has been translated automatically.
- Harmful external and internal mechanisms are discussed.
- External: physical influences such as UV-rays, X-rays, exposure to light sensitizing substances such as tar products.
- Internal/external: damaging metabolites that induce elastosis in connection with UV radiation (e.g. porphyrins; dialysis; alcohol; nicotine).
- Occurrence has been described in clinical pictures such as Pseudoxanthoma elasticum, chronic UV damage, actinic elastosis, farmer's skin, X-ray elastosis, tar skin, porphyria cutanea tarda, renal insufficiency, elastoidosis cutanea nodularis et cystica.

- Skin areas exposed to light; forehead, nose, cheeks, neck.
Notice! Other areas such as the back of the hands, forearms and neck react less with clumpy elastosis than with dermal atrophy. An example of this is the erythrosis interfollicularis colli.
Clinical featuresThis section has been translated automatically.
- Circumscribed, congenital elastotic skin changes are found in Pseudoxanthoma elasticum.
- Acquired elastosis: Clinically, a coarsened skin relief with pronounced macro-wrinkle formation is impressive. The skin is flaccid, wrinkled and coarse-fielded in the areas exposed to light. When the skin is stretched, a yellowish net pattern can be seen in the dermis. An increase in elastotic deposits leads to the formation of soft, skin-coloured to slightly yellowish, patch-like skin fields (see also Elastosis actinica). The "elastotic" degeneration of the skin leads to a loss of skin tension, to an increased formation of wrinkles, to a widening of the skin pores. This loss of elasticity leads to the clinical picture of elastoidosis cutanea nodularis et cystica in the face (in "weather-tanned people"), especially above the zygomatic bones.
- On the neck, this impresses in a particularly coarse-meshed skin field with deep wrinkles as Cutis rhomboidalis nuchae.
