BCC: basal cell carcinoma ENL: erythema nodosum leprosum LL: lepromatous leprosy MS: multiple sclerosis INTRODUCTION Leprosy, also known as Hansen disease, is a chronic bacterial disease caused by Mycobacterium leprae. M. leprae has low pathogenicity and virulence, developing over many months to even decades, and has the potential to cause extensive damage to the skin and peripheral nervous system. Here we present a patient with a history of multiple sclerosis (MS) who presented with 3 lesions that clinically appeared like basal cell carcinomas (BCC). After biopsies were collected, pathology revealed lepromatous leprosy (LL).
