Among the several mental disorders, schizophrenia was the first, where the association of specific dermatoglyphic features with the illness was investigated by Blümel and Poll (1928). From that time the schizophrenia as one of the most common mental disorders has aroused a great interest in clinical dermatoglyphics. In spite of the number of publications, results have been disappointing and the findings among various studies have been contradictory.
Dermatoglyphics began with dactyloscopy in Hungary in the early 1900s. Since then, the interest in several fields of dermatoglyphics has arisen, e. g. paleodermatoglyphics, heredity of the dermatoglyphic traits, dermatoglyphics in medical disorders, dermatoglyphics of different populations in Hungary, dermatoglyphics in questioned paternity as well as the study of the palmar and plantar creases. Due to the numerous studies published in these fields, it is impossible to list all of them, therefore this paper highlights only the results of some of them.
