|Description:||The face of this male patient exhibited some of the pathologic characteristic associated with a case of nodular lepromatous leprosy, which under the newer World Health Organization (WHO) standards, is classified as multibacillary (MB), leprosy. Of note is the presence of cutaneous nodules upon the forehead, nose, cheeks, lips, and chin. The eyebrows are diminished as well. This illness is caused by the bacterium, Mycobacterium leprae.|
MB leprosy is characterized by generalized, or diffuse, involvement of the skin, under microscopic examination, a thickening of the peripheral nerves, and has the potential to involve other organs including the eyes, nose, testes, and bone. The nodular form of this condition is the most advanced form of the disease. Ulcerated nodules release large numbers of M. leprae bacteria.
