The mark left by a healed wound (4)
I believe the answer is:
scar
'the mark left by a healed wound' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for scar that I've seen before include "Stigma" , "Bare craggy rock" , "Visible mark of healing" , "Fish" , "Craggy outcrop" .)
