Solar elastosis

Solar elastosis

Actinic elastosis, also known as solar elastosis, is an accumulation of abnormal elastin (elastic tissue) in the dermis of the skin which occurs as a result of the cumulative effects of prolonged and excessive sun exposure, a process known as photoaging HISTOPATHOLOGY:Elastic fiber proliferation can be seen in the dermis. As the condition becomes more established, the collagen fibers of the papillary dermis and reticular dermis become increasingly replaced by thickened and curled fibers that form tangled masses and appear basophilic under routine haematoxylin and eosin staining. These fibers stain black with the Verhoeff stain.The haematoxyphilic elastic fibres called as basophilic degeneration are separated from the epidermis by a narrow band of normal appearing collagen (Grenz zone )with collagen fibres arranged horizontally.
