Uncommon Palm Prints: Can They be Used for Forensic Identification?

Sir, Finger and palmar print evidence is a reliable source for personal identification in forensic science (1–3). Although details of the epidermal ridges are unique for an individual, generally finger and palmar patterns can be classified as arches, loops, and whorls. These patterns complete their fetal development by midsecond trimester, and their final expression is influenced by both genetic and prenatal environmental factors (4). Thereafter, the patterns remain unchanged except for an increase in size due to growth and minor alterations in appearance as a result of use, aging, and possible injury.
