Contused Wounds And Injuries Unaccompanied By Solution Ofcontinuity
If a blow be inflicted with a blunt instrument, there is produced a
bruise, or ecchymosis, of which it is unnecessary here to describe the
appearance and progress. A bruise may be distinguished from a
post-mortem stain by the cuticle in the former often being abraded and
raised. When an incision is made into the bruise, the whole of the
subcutaneous tissues are found to be infiltrated with blood-clot, and
there is no clear margin. In the case of a post-mortem stain the edges
are sharply defined, not raised, and, on section, mere bloody points
are seen which are the cut ends of the divided blood vessels.
