The forensic evidence of hanging is based on the autopsy demonstration of the traces left by the noose or the ligature on the neck, as well as on the histological assessment of the hanging mark vitality. However, the specific topography of haemorrhagic infiltration in the context of the cervical damaged tissues involved in hanging is not known. We carried out an extensive microscopic examination to identify if haemorrhagic infiltration in hanging appeared in specific topographic locations that could have been considered as elective. From 102 victims of suicidal hanging, a skin fragment was sampled from the maximum compression area of the sulcus, including the skin portions immediately above and below it. The sampling was also extended to collect the subcutaneous adipose tissue and part of the striated muscle. A standard histological examination was performed on all the samples, and hematoxylin and Eosin, Weigert's resorcin-fuchsin and Goldner's Masson trichrome staining were performed. In all the cases assessed, the microscopic examination allowed the detection of haemorrhagic infiltration mainly in the deepest areas under the sulcus and especially in the deep dermis and at the transition point between the dermis and the subcutaneous adipose tissue, as well as in the context of its supporting connective tissue. Such areas could therefore be considered as regions in which the presence of haemorrhagic infiltration is more likely to be demonstrated. Accordingly, we recommend performing sampling similar to ours and focusing the search for haemorrhagic infiltration as suggested.
绞刑的法医学证据基于套索或结扎物在颈部留下的痕迹的尸检证明，以及对绞刑痕迹活力的组织学评估。然而，在涉及绞刑的颈部受损组织中，出血浸润的具体局部解剖位置尚不清楚。我们进行了广泛的显微镜检查，以确定在绞刑中出血浸润是否出现在可以被认为是选择性的特定局部解剖位置。从 102 例自杀绞刑受害者中，从切迹的最大受压区采集皮肤碎片，包括其上下的皮肤部分。取样还扩展到收集皮下脂肪组织和部分横纹肌。对所有样本进行了标准的组织学检查，并进行了苏木精和伊红、Weigert 间苯二酚复红和 Goldner 三色染色。在所有评估的病例中，显微镜检查允许检测到出血浸润主要在切迹下方的最深区域，特别是在真皮深部和真皮与皮下脂肪组织的交界处，以及其支持性结缔组织中。因此，这些区域可以被认为是更有可能显示出血浸润存在的区域。因此，我们建议进行类似于我们的取样，并按照建议寻找出血浸润。
