Solar elastosis is histologically characterized by an elastotic change in the upper dermis.1 During a study of solar elastosis, I noted a band-like loss of dermal elastic tissue (elastolysis) in the middle dermis of biopsy specimens from the sun-exposed skin of one individual. This unique, apparently suninduced phenomenon is reported.
Report of a Case
A 72-year-old man had noticed wrinkling of the skin of the sun-exposed areas, especially the face, neck, and extensor aspect of the forearms, for many years. Past history indicated an appendectomy at the age of 16 years. There was no history of urticaria or any other inflammatory or noninflammatory skin disorders except for sunburn. Results of a general physical examination were normal. The skin of sun-exposed areas was thick, wrinkled, and leathery (Fig 1). There were no signs of atrophy or inflammation; there were no circinate margins in the affected areas. Complete blood cell count,
