Elastosis perforans serpiginosa. This rare skin disease causes abnormal elastic fibres to be expelled through the skin. This process, known as transepithelial elimination, leads to the red lesions seen here. It may be caused by use of the drug D-penicillamine, or secondary to a systemic disease such as Down syndrome, osteogenesis imperfecta or Marfa syndrome. However, most cases have no known cause. Most cases will resolve of their own accord, but treatment with cryotherapy (liquid nitrogen) may help more stubborn cases.
