Characteristic dermatoglyphic patterns are found on the volar aspect of the skin of the primates including, man, apes, monkeys and some kinds of marsupiaIs. It is the delieate continuous or discontinuous and sometimes interrupted or branched, variable shaped configuration of ridged skin patterns, which is composed of the unit pattern of arch, loop and whorl. It is characteristically unique for any individuals so it has been used popularly as a convenient method of personal ideatification or for use in studies of inheritance epecially i the field of Iegal medicine. Besides that, there are statistieal differences between left and right finger, males and femals and different races. Of particular interest is the fct the distortion of the dermatoglypbic patterns occur in relation to cbromosomal aberrations, for exarnple, in mongolism,Klinefelter's syndrome and Turner'e syndrome. In addition to that, dermatoglyphic features may prove and aid to diagnree in dermatology, such as, in alopecia areata, psoriasis and leprosy. Thus, authors studied on the dermatoglyphic pattern types in the 234 cases of healthy normal males, 44 male psoriatic patients and 58 male alopecia areata patients during the period of 10 months from Novernber, 1977 to August, 1978, The resulta are as follows: A. Psoriasis 1. In the analysis of the total fingertip ridges, there are significant differences (p<0.01) between the alopecia areata (141.66+/-8.36) and the control group (152.93+/-9.50). 2. A significant statistical difference between the psoriasis and the control group does not exist with respect to the pattern intensity. 3. In the incidence of simian lines, the psoriatic patients (15.91%) showed more incidence rate than those of control group (8.98%). 4. With respect to the proportional distance (mm.) between the distal flexion crease of the wrist to the base of the middle finger with the distance (mm.) of the same point of the wrist to the axial triradius, a significant statistical difference (p<0.05) between the left hands of the control gorup (15.24+/-0.37%) and, those of psoriasis (17.35+/-1.01%) was existed. 5. As for the and angle, there is no significant differences between the control and psoriasis group. 6. There is no statistical differences in view point the pattern types between the psoriasis and the control group, however in psoriasis group, double whorls are decreased than those of control gorup (6.8%). B. Alopecia areata 1. In the analysis of the total fingertip ridges, there is significant difference (P<0.01) between the Alopecia areata (138.40+/-5.03) and the control group (152.93+/-9.50). 2. A significant statistical differences (P<0.005) between the alopecia areata (14.193+/-0.487) and the control group (14.728+/-0.182) exist with respect to the pattern intensity. 3. In the incidence of simian lines, the alopecia areata patients (3.44%) showed lower incidence rate than those of control group (8.98%). 4. With respect to the proportional distance (mm.) between the distal flexion crease of the wrist to the base of the middle finger with the distance (mm.) of the same point of the wrist to tbe axial triradius, a significant statistical difference(p<0.05) between the left hands of the control group (15.24+/-0.37%) and those of alopecia areata (16.66+/-0.70%) was existed. 5. As for the and angle, it is increased significantly (P<0.01) in both hands of alopecia areata, especially in the right hands of alopecia areata, it is increased about twice that of control group. 6. There is no statistical differences in the pattern types between alopecia areata and control group, however in alopecia areata patients, whorls in the right index finger are decreased (39.66%) than those of control gorup (50.16%), Whereas loops in the right index finger are more freguently found (50%) than those of control group (37.44%).
