This Month in JAAD Case Reports: May 2024 Mycobacterium lepromatosis in Wisconsin

Hansen ’s disease (HD) does not spread easily from person to person, as prolonged contact with someone with untreated leprosy over many months is needed to become infected. There are approximately 150 new cases of leprosy in the United States every year. The vast majority of these are in immigrants or tr avelers from endemic areas.1 For approximately 150 years, Mycobacterium leprae was considered to be the sole cause of HD. Yet in 2008, Mycobacterium lepromatosis was identified as a new species and causative agent of HD.
