Nontuberculous mycobacterial infection in a sporotricoid distribution in Korea: a case report

 Nontuberculous mycobacterial infections, often acquired from environmental sources like water and soil, present diverse cutaneous manifestations, leading to frequent misdiagnoses and therapy delays. A 77-year-old woman presented with multiple skin lesions in a sporotricoid distribution on her right leg, which persisted despite of standard antibiotic treatments. Based on histologic examination and PCR testing, nontuberculous mycobacterial infection was diagnosed. The case highlights the necessity for high suspicion and appropriate diagnostic techniques, including tissue biopsies and molecular methods like PCR.
