Caption:
This photomicrograph reveals some of the histopathologic changes in a specimen of human testicular tissue, which included a large number of foam cells. These changes were attributed to a case of lepromatous leprosy, which under the newer World Health Organization (WHO) standards, is classified as multibacillary (MB) leprosy, and is caused by the bacterium, Mycobacterium leprae. Foam cells are macrophages that have ingested, or phagocytized, M. leprae bacteria, but are unable to digest the organisms, who in turn multiply, and use the macrophage as a method of transport throughout the body.
