n.

Elastosis in the sun-exposed skin of old persons or in those who have chronic actinic damage.

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.

solar elastosis

Degeneration of subdermal elastic tissue by prolonged sun exposure, causing wrinkling 'sailor skin'–aka, farmer's skin, golfer's skin, which predisposes skin to malignancy–eg, BCC, SCC, melanoma. See Actinic–solar keratosis.
