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.

so·lar e·las·to·sis

elastosis seen histologically in the sun-exposed skin of the elderly or in those who have chronic actinic damage.

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.

so·lar e·las·to·sis

(sō'lăr ĕ-las-tō'sis)

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

In the patients with invasive melanoma, 59% of cases occurred in sun-exposed sites, and the presence of solar elastosis correlated significantly with greater depth of invasion, Dr.

In the study of melanoma in situ, 38% of all patients showed moderate or severe solar elastosis within the papillary dermis, and 39% had mild solar elastosis.

Least likely to have solar elastosis were the buttocks, nails, feet, and legs.

Melanoma risk associated with solar elastosis

Alternative possible explanations for reduced mortality include the idea that the more aggressive types of melanoma are not the types associated with UV light damage, or that the collagen deposits and other skin changes that come with solar elastosis form a barrier to invasiveness and/or metastasis.

Melanoma experts grapple with the sun question: one hypothesis is that vitamin D may help protect against cancer, but epidemiologic evidence is scant

We found a statistically significant relationship between the mean age of the patients and solar elastosis, splinter haemorrhage and longitudinal ridging.

We also found a statistically significant relationship between the patients' job and solar elastosis and folliculitis; this has not been reported previously.
