Skin bruising are the most frequent lesions found in cases of physical aggression. Product of blood vessels rupture (especially capillaries), leading to extravasation and accumulation of blood in the intradermic tissue, subcutaneous tissue or both. After that, begins a local inflammatory process leading to the degradation of hemoglobin chromophore subproducts (hemosiderin, biliverdin, bilirubin, methemoglobin) which give the initial coloring and changes over the time. The visual method used for decades is ineffective and the best approach is looking por the presence of the color yellow into the bruise. At present, new methods are developing to improve the dating of injuries that seem quite promising (spectrophotometry and magnetic resonance).
