Dermatoglyphic examination of the dermal surface of bodies in advanced postmortem condition

A new technique was applied to examine dermatoglyphic characteristics in dead bodies in advanced postmortem conditions. For this purpose, the volar skin was first fixed in formalin, incubated in 1 N potassium hydroxide solution, and then the dermis was exposed. Dermatoglyphic features were inspected on the dermal surface by staining with toluidine blue solution. This technique may be useful in cases in which the regular examination process does not provide favourable results because of advanced decomposition of the skin.
