Currently, two major perforating diseases include reactive perforating collagenosis and elastosis perforans serpiginosa. In some literature, acquired perforating dermatosis is a third major group and is a catch-all term for cases of perforating disease arising in adults, usually associated with a systemic disease. Kyrle disease is characterised by the formation of large papules with central keratin plugs and is often associated with hepatic, renal or diabetic disorders.

Outside of the glass vial is another chemical called phenyl oxalate ester.
