Abstract:

Blister skin injury is a common type of skin injury in the practice of forensic examination. At present, there is no special report. It can be caused by a variety of external factors, with epidermolysis and blister formation as the main changes. The injury factors include mechanical, physical, toxic and corruption, and show different morphological characteristics, which is of great significance to infer the time, mode and cause of death. Firstly, through literature review, this paper reviews the historical origin and research status of blister skin injury. Secondly, combined with forensic practice, this paper discusses the basic concept and basic structure of blister skin injury, tentatively puts forward the concept and definition of blister skin injury, and believes that its nature belongs to closed epidermal injury, which will be conducive to forensic pathology Finally, the common types of blister skin injury such as mechanical injury, burn and scald are introduced, and the key points of further classification and differential diagnosis are given for reference.

Key words:

摘要：

疱性皮肤损伤是法医检验鉴定实践中常见的一种皮肤损伤类型，目前尚未见有专门性报道，其可由多种外界因素所致，以表皮松解、皮疱形成为主要改变。致伤因素包括机械性、物理性、毒物性和腐败性等，并表现出不同的形态特征，对于推断死亡时间、死亡方式、死因等有重要意义。首先通过文献复习回顾了疱性皮肤损伤研究的历史渊源和研究现状，其次结合法医实践就疱性皮肤损伤基本概念、基本结构等进行了法医学探讨，试探性提出了疱性皮肤损伤的概念和定义，认为其损伤性质属于闭合性表皮损伤，这将有利于法医病理学、损伤学中皮肤损伤类型理论体系的完善，最后介绍了机械性损伤、烧烫伤等常见的疱性皮肤损伤类型，给出了进一步的分型和鉴别诊断要点，供同行参考。
