Summary

Injecting blood under the skin creates a hematoma that can be shaped by external pressure. This study shows how pressure on a hematoma can alter its appearance over time.

Area of Science:

Forensic pathology
Dermatology

Background:

Hematomas form after blood is injected into the subcutaneous tissue.
Understanding hematoma changes is crucial for forensic and medical assessments.

Observation:

In living subjects, applying pressure to induced hematomas resulted in patterned blanching or intensity differences.
These changes became more pronounced over several days.

Findings:

External pressure applied to hematomas can induce visible, lasting patterns.
Higher pressures and blood volumes in cadavers created distinct imprints within an hour.

Implications:

This research may aid in interpreting patterns found on bodies in forensic investigations.
The findings could inform medical assessments of injuries involving subcutaneous bleeding.
