Abstract

Even if the Amussat's sign is known since the mid-19th century, few studies have been made in order to assess its real occurrence. In particular, the histopathologic examination of the Amussat's sign lacks in the medicolegal literature. The review of the literature shows indeed a significant range of variability (from 1.1 % up to 25 %) regarding the macroscopic detection of the Amussat's sign. In this study, the authors report that the identification of a vital Amussat's sign is important and may require the immunohistochemical staining for the Glycophorin A (a marker of vital reaction). The victim was a 63-year-old man, who was found suspended from the staircase with a rope. Both the carotid arteries were opened in situ by using fine scissors with blunt tips. A horizontal lesion (length 4 mm) of the intima of the left common carotid artery was documented. A sample was obtained; then, a standard post-fixative histopathologic examination and immunohistochemical staining for the Glycophorin A were carried out. The standard histopathologic examination only revealed the intimal laceration with a poor hemorrhagic infiltration. However, the immunohistochemical staining for the Glycophorin A allowed the clear identification of the hemorrhagic infiltration, which was documented both in the intimal laceration and in the periadventitial soft tissues. The immunohistochemical staining for the Glycophorin A can identify the vitality of an Amussat's sign. When an Amussat's sign is documented, the Glycophorin A may therefore help the forensic pathologist to differentiate a hanging death from a postmortem suspension of the body.
