Hansen's disease (leprosy) is a chronic infectious disease caused by Mycobacterium leprae which affect mainly skin and nerve systems. Currently the incidence of leprosy reached the goals set by WHO in the year 2000. In recent 10 years, only 47 new patients were found in Koreans and their average age was over 70. A 21 year-old young man showed multiple erythematous papules, macules and plaque at face, extremities and trunk. In family history, his grandfather was diagnosed with leprosy at young age and leprosy was recurred when the patient was 7 years old. The patient lived with grandfather from birth to 7 years old. Clinico-pathologically he was diagnosed with a lepromatous leprosy. We performed VNTR both at the skin tissue of grandfather and patient to find out the infection pathway of the patient and found some consistent. Herein, we report a new case of young Korean male transmitted from grandfather.
