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.
