Incidentally discovered elastosis in skin that may have received prolonged sun-exposure can be presumed to be solar elastosis if there are no characteristics of any differential diagnosis thereof.

==Reporting==
*The presence of elastosis, with the most probable cause thereof.
In incidentally discovered solar elastosis in case of another disease, description may be brief, such as "Solar elastosis (optionally:, also in surrounding skin)."
