Leprosy is a chronic infectious disease caused by Mycobacterium leprae and, depending on the host immune status, presents different clinical forms. This report describes the case of a 46-year-old man who had hypoesthetic lesions in the infrahyoid region for 30 days. The bacilloscopy was negative. The anatomopathological examination showed alterations corresponding to the tuberculoid pole (epithelioid histiocytes) and virchowian pole (foamy histiocytes), compatible with borderline-virchowian leprosy (Ridley and Jopling classification). Rapid tests for HIV I, II, and syphilis were positive, with a CD4 count of 223. The patient started treatment with multibacillary multidrug therapy, antiretroviral therapy, and benzathine penicillin, with marked clinical improvement in two months.
