Medical Sementics: surgical treatise on cutaneous marks of violence

Abstract

Background: There is relative illiteracy in the general knowledge of appropriate medico-legal terminology and clinical documentation of cutaneous marks of violence. In a resource-limited setting like in Zambia, appropriate diagnostic labels and accurate documentation of the injuries is critical as photographic and other scientific means of securing medical evidence becomes less cost effective.

Objectives: The object of this review paper is to impart important lessons in standardizing medical terminology and documenting cutaneous marks of violence and highlight pitfalls in differential diagnoses of the injuries.

Method: Asystemic literature search for cutaneous marks of violence was made in African Journals Online, PubMed and Forensic Medical journal websites for the period 2000 to 2025, using cutaneous trauma; injuries; wounds; forensic terminology and documentation of injuries as keywords.

Results: There were several results of interest from the search for pertinent information. A narrative of the injuries was synthesised primarily from authoritative textbooks of Forensic Pathology augmented by authors' personal knowledge of medical jurisprudence. The injuries were conventionally categorised as bruises, abrasions, lacerations, incisional wounds and stab wounds. They were of varying severity ranging from minimal to clinically serious injuries. The injuries were caused by blunt or sharp force impacts in a variety of ways with many types of objects. They were accidental, self-inflicted or homicidal trauma, depending on the circumstances. An inspection of the clothes for fabric damage and bloodstain gravitation provided clues about the incident.

Conclusion: Clinicians are reminded of innocent differential diagnoses which simulate accidental, self-inflicted and homicidal trauma. The diagnostic labels must be qualified with an objective clinical description, backed up by scaled colour photographs. The medical history should correlate with the pattern and distribution of injuries. It is good medical practice to ensure that the medical evidence withstands the rigour of clinical challenges in the judicial system. It may not be apparent at the outset whether the description and interpretation of the injuries would become considerably significant should medico-legal proceedings ensue.
