The assessment of injury patterns in forensic practice sometimes requires separation of self inflicted injuries from those that have been inflicted by another, as the medicolegal significance of each is entirely different. Certain repetitive features are found in self inflicted injuries that may assist in identifying these cases. Non-lethal self inflicted injuries are usually incised, and are located in areas of the body that are accessible. Common areas include the forearms, anterior thighs, forehead, cheeks, upper chest and abdomen . The lesions tend to occur on the opposite side to the dominant hand and are not found in sensitive areas such as the eyelids, genitalia or nipples, unless there is a serious underlying psychiatric disturbance. Typically the clothing has been carefully lifted before the wounds are inflicted in contrast to assaults where stab and slash wounds often cut through overlying fabric [2, 3].
