Previous issue date: 2007-07-31 / In Brazil, there was a significant increase of deaths due to external causes resulting from wounds of firearm projectiles. This kind of wound is the third cause of Brazilians? deaths, after cardiac and cerebral vascular diseases. Taking into account the necessity of public and social order, both the Medicine and Forensic Justice have interest in victims of wounds of external causes. In this case, Justice searches in the medical science a set of juridical knowledge to help it to defend the rights and interests of men and society: this is the Forensics Medicine. The Forensic Physician has to be able to provide the causa mortis as well to describe the wounds of the Justice interest. In the cases associated with firearms, this physician has to determine if the orifice from the projectile in the body is of entrance or exit. This is very important according to the juridical and proceeding point of view. The firearm projectiles cause in the human skin several typical wounds; however, the shot direction or if the wound occurred due to the entrance or the exit of the projectile are not always determined macroscopically by the forensic physician. Therefore, other means, as the histological, to provide an accurate diagnosis should be taken into account. This study analyzed macroscopically and microscopically 14 wounds of entrance and their 14 wounds of exits, comparing data with the related in the literature. This study showed that hystopathological analysis of wounds due to firearm projectiles provides an effective diagnosis of the entrance and exit orifice. Coagulation necrosis of keratinocytes associated with subepidermal fissure (effects of burn injuries) is a pathognomonic feature of the entrance orifice, whereas the presence of adipose, muscle and bone tissues in the derm is characteristic of the exit orifice. / No Brasil, nos ?ltimos anos, houve um aumento acentuado de mortes por causas externas, devido a ferimentos de proj?teis de arma de fogo. Atualmente, os ferimentos causados por armas de fogo s?o a terceira causa de morte entre os brasileiros, atr?s somente das doen?as card?acas e das c?rebro-vasculares. As v?timas dos ferimentos por causas externas s?o de interesse da Medicina e tamb?m da Justi?a, levando-se em considera??o as necessidades de ordem p?blica e social. Neste caso, a Justi?a busca na ci?ncia m?dica um conjunto de conhecimentos extrajur?dicos para auxili?-la a defender os direitos e os interesses dos homens e da sociedade: ? a Medicina Legal. Compete ao M?dico Legista estabelecer a causa mortis e descrever os ferimentos de interesse da Justi?a. Nos casos que se correlacionam com armas de fogo, compete ao mesmo determinar se o orif?cio decorrente do proj?til no corpo humano ? de entrada ou de sa?da, tendo este fato suma import?ncia do ponto de vista jur?dico e processual. Os proj?teis de arma de fogo ocasionam na pele humana uma s?rie de ferimentos t?picos, mas nem sempre possibilitam o m?dico legista estabelecer, do ponto de vista macrosc?pico, a dire??o do tiro ou se um ferimento foi ocasionado pela entrada do proj?til ou pela sua sa?da. Deve-se, ent?o, lan?ar m?os de meios mais precisos ? histol?gicos ? para se estabelecer o diagn?stico de certeza. Este estudo analisou 14 ferimentos de entrada e suas 14 respectivas sa?das, do ponto de vista macrosc?pico e microsc?pico, comparando-se com os dados j? existentes na literatura. Este estudo demonstrou que a an?lise histopat?logica dos ferimentos ocasionados por proj?teis de arma de fogo fornece substrato para o diagn?stico mais acurado do orif?cio de entrada e de sa?da, sendo que a necrose de coagula??o dos ceratin?citos associada ? fenda sub-epid?rmica (efeitos de les?o por queimadura) ? caracter?stica de orif?cios de entrada e a presen?a de tecido adiposo, tecido muscular e tecido ?sseo, na derme, ? caracter?stica de orif?cio de sa?da.
