Gunshot wounds may encompass a broad range of injuries involving soft tissues, bones, blood vessels and other underlying structures, including vital organs [1]. The extent of the injury and the appearance of the wound will depend on two factors: the velocity of the bullet or missile and the proximity of the weapon at the time of firing. Firstly, bullets are classified as low-velocity (with a speed of < 600 m/s) or high-velocity (> 600 m/s), and high-speed bullets which are more likely to cause deep penetrating injuries [1] [2]. Secondly, studies have divided the appearance of a gunshot wound into four main categories, depending on the distance of the firearm to the body [3]:

• Contact wound - This type of injury will be easily distinguished by the presence of an imprint of the muzzle that is held against the skin at the time of firing, whereas a prominent and wide stellate pattern of the entrance wound as a result of excessive heat, carbon monoxide and the effects of soot on the skin will be observed [3] [4]. Adjacent reddening of the skin is frequent, and the margins of the entrance wound are seared and often black, without a wide zone of soot deposition [3] [4]. The stellate pattern of skin damage in contact wounds is typically seen, but it must be carefully examined, as certain firearms (eg. rifles) may produce an exit wound that has identical macroscopic features [4].

• Near-contact wounds - Contrary to contact wounds, soot deposition around the entrance wound is frequent in near-contact wounds [3] [4]. Moreover, they are likely to occur when the gun is held at an acute angle to the skin, producing an irregular pattern of soot on the skin [3] [4].

• Intermediate and distant wounds - The absence of soot and surrounding redness of the skin will not be present in gunshot wounds that are inflicted at least two feet away from the victim, and are thus termed intermediate and distant wounds [3] [4]. A pathognomonic feature of close-range or intermediate wounds is the presence of skin tattooing, which demarcates the embodiment of gunpowder into the surrounding skin [4]. Conversely, the absence of skin tattooing indicates that the bullet entered the skin from a significant distance [4].

Immediate inspection of the wound and assessment of the presence of an exit wound is the first important step in the diagnostic workup and it is necessary for determining further care. The shape of the wound, its pattern, borders, as well as the presence (or absence) of soot are essential steps, while history taking (if possible from the patient or from accompanying persons) is equally important. After a full clinical workup, imaging studies in the form of plain radiography, computed tomography (CT) and ultrasonography need to be employed, in order to evaluate the extent of tissue injury, including the subcutaneous tissues, blood vessels, bones and vital organs [2] [5] [6] [7]. Although some authors have concluded that the potential risks of using magnetic resonance imaging (MRI) as an imaging method are significantly outweighed by its potential benefits, physicians should be cautioned about performing MRI as metallic objects and bullets in the vicinity of important structures could get dislodged and cause secondary injuries [2] [5].
