Introduction and Aims 
To the majority of health professionals, burns present a challenging, potentially distracting, diagnosis. Because of their perceived complexity, they often eclipse other medical problems which can be life threatening. Pressure necrosis may present with full thickness skin loss and in extreme cases expose underlying structures. In rare instances, such necrosis may mimic and be mistaken for full thickness burns. Such long lies may cause pressure necrosis of decubitus areas and compartment syndrome of vulnerable areas. Compartment syndrome, is a surgical emergency requiring prompt diagnosis and intervention. It may be missed in the context of a long lie after collapse. Such missed diagnoses, maybe detrimental to patients’ outcomes. Herein we present two such cases .
Material and Methods 
We reviewed cases referred to our unit in the last four months, their clinical notes and medical photography. We have also performed literature search to find similar case reports.
Learning points
Two cases, with acute pressure necrosis from long lies had been mistaken for burn wounds, were referred to our burns unit in last four months. In one case a missed compartment syndrome resulted in a below elbow amputation. Images, with consent for publication, show a mode of injury causing pressure necrosis.  
Conclusion
Pattern analysis and recognition are very important diagnostic tools in medicine.  Detailed history taking and examination cannot be emphasised enough. Training both emergency departments and plastic surgeons in recognising long lie related injuries will decrease possible associated dangers such as missing a compartment syndrome.
