Background: Poroscopy is the term applied to the study of the pore characteristics found on the papillary ridges of the skin as a method of identification which was proved to be reliable and accurate Objective: The goal of this work was to examine the epidermal pores among the adult Upper Egyptians and to detect the influence of gender on their frequency, type, size and shape. So far, no previous research handled this topic on the Upper Egyptians
Subjects and methods: The inked left thumb prints of 200 adult Upper Egyptians [100 males and 100 females] within an age range of 18 – 20 years were examined Conclusion: The characters of the pores present on the papillary ridges of the skin may be used as means of identification and sexual differentiation for the Upper Egyptians
