It is certain, however, that the growth, and therefore the evolution, of the seborrheic keratoses is enhanced by hormonal alterations or irritation, although not the triggering cause: for this reason menopause, a moment of high hormonal modulation, coincides with the strengthening of warts seborrheic.
Finally, some studies also suggest a possible involvement of UV radiation in the etiology of the disease, since it has been noted that seborrheic keratosis occurs in people who have exposed their skin to the sun for prolonged periods. However, since the disorder occurs even in individuals who have not been excessively exposed to UV radiation, the debate about whether or not sunlight is involved in the etiology of seborrheic keratosis is still open. Therefore, further and more in-depth studies need to be conducted.

The papules can have different sizes, both according to the subject and according to the area affected by the keratosis: generally, a diameter from 1 millimeter to 1 centimeter is recorded, but there have been cases in which the papules are even more evolved .
Often, seborrheic keratoses appear to be barely attached to the skin and feel as if they are peeling off easily. Precisely because of the precariousness with which the seborrheic keratoses are attached to the skin, it is not uncommon for them to be partially or completely eradicated following a trauma.
Given the similarity with warts, seborrheic keratosis is known by the term seborrheic wart: the seborrheic formations are not contagious, nor infectious and, as mentioned, they cannot evolve into malignant tumor forms.

After removal of the seborrheic keratosis, the skin usually appears a lighter color than the surrounding skin. This hypopigmented area can remain so for the entire life span of the patient.
However, the treatment leads to permanent removal of the lesion, as it will no longer manifest in the area it was removed from. However, this does not prevent new seborrheic keratoses from appearing in other untreated areas of the body.
