<prompt> Which feature would most likely be found in a patient with lepromatous leprosy?No bacteremiaMacrophages with a foamy appearance in the dermisA positive lepromin reactionA high cell-mediated response against Mycobacterium leprae  <response>: The disease of leprosy is divided into two basic types: lepromatous and tuberculoid. The lepromatous form is an aggressive disease, whereas the tuberculoid form tends to be self-limiting. Individuals with lepromatous leprosy have an inflammatory skin infiltrate, which consists largely of macrophages that have a characteristic vacuolated or foamy appearance caused by the accumulation of lipids within phagocytes and intracellular acid-fast bacilli. In the lepromatous form, presence of organisms indicates impaired cellular immunity, unlike the tuberculoid type, which can effectively kill the bacteria.
