Livor Mortis: Scans From Gresham's Colour Atlas of Forensic Pathology (1975)
These scans are from A Colour Atlas of Forensic Pathology by G. Austin Gresham, first published in 1975 in the Wolfe Medical Atlases series. Gresham was a Cambridge professor of morbid anatomy and histopathology and a Home Office pathologist, and the book was written as a pocket reference for trainee pathologists to carry in the field. Livor mortis, also called postmortem lividity or hypostasis, is the settling of blood in the lowest parts of the body after death, staining the skin pink to dark purple. It can show within 20 minutes to 2 hours of death, becomes obvious over the next several hours, and is usually fixed by 8 to 12 hours, meaning the discoloration no longer fades when pressed. Investigators read it two ways: fixed lividity on the wrong side of a body shows the body was moved after death, and unusual coloring can point to certain causes of death such as carbon monoxide poisoning. Not every figure in this set shows lividity; the atlas covers the whole of forensic pathology, and some of the images show bruising and other findings. |
