Dermatoglyphics in leprosy: (III) Creases of palm.

Palmar configurations of triradii and creases of 100 leprosy patients [50 lepromatous (BL/LL) and 50 tuberculoid (BT/LL)] were compared with those of 100 normal persons selected from families of these patients. The patterns of position of triradii were similar in controls and leprosy patients as such. But, the patterns in the two types of leprosy patients were different. As for palmar creases patterns, there was significant difference between those of controls and patients, double radial base crease occurring more often in patients. However, the differences between the two types of patients were not statistically significant.
