Abstract. Introduction. Determining the postmortem interval is usually based on macroscopic-
morphological criteria (cadaveric phenomena); some other objective methods are often difficult to access
in daily practice; therefore we analyze the usefulness of the histopathological examination of the skin as a
supplementary method for determining the postmortem interval. Mater ials and methods. 23 patients and
92 skin biopsies were analyzed. All samples were taken in a maximum time of 6 h postmortem. Biopsies
were classified into 4 groups according to the postmortem interval, with 23 biopsies in each group: 1 (1 to
6 h.); 2 (25 to 30 h.); 3 (49 to 54 h.); 4 (73 to 78 h); 21 histological criteria were analyzed with Fisher test
and principal component analysis. Results. Skin biopsies of 23 corpses (mean age 51.6 years, 15 males
and 8 females) were studied. 21 histological criteria were analyzed by Fisher test; statistical significance
(p <0.001) with a reliability of 94.61% was achieved in 15 parameters. With the 15 selected parameters, a
principal component analysis established that there were differences among the 4 analyzed groups.
