ransepidermal elimination is a disorder in which T dermal stimuli profoundly effect the behavior and structure of the overlying epidermis. Briefly, there are two categories of disorders: the first are primary dermatoses and consist of elastosis perforans serpiginosa and reactive perforating collagenosis; the second group originates from alterations of dermal constituents in preexisting disorder...

IN recent years there have been many references to angioid streaks of the retina found in association with pseudoxanthoma elasticum and Paget's disease of bones (Elwyn, 1953; Cowper, 1954; Bedrossian, 1958; Hogan and Zinmerman, 1962). A review of the current literature on angioid streaks and on brain tumours revealed no cases of angioid streaks in patients who presented with ocular manifestatio...

Transepidermal elimination (TE) is a mechanism whereby foreign or altered constituents can be removed from the dermis. This process involves unique morphologic alterations of the epidermis, which forms a channel and thereby facilitates extrusion of the desired dermal components. The phenomenon of TE may occur as a primary process characterizing disorders, such as elastosis perforans serpiginosa...
