[Illustration: FIG. 99.--Multiple Sebaceous Cysts or Wens; the larger
ones are of many years' duration.]
_Treatment._--The removal of wens is to be recommended while they are
small and freely movable, as they are then easily shelled out after
incising the overlying skin; sometimes splitting the cyst makes its
removal easier. Local anaesthesia is to be preferred. It is important
that none of the cyst wall be left behind. In large and adherent wens an
ellipse of skin is removed along with the cyst. When inflamed, it may be
impossible to dissect out the cyst, and the wall should be destroyed
with carbolic acid, the resulting wound being treated by the open
method.
