|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 dispersed over the entire face. The eyebrows are missing 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, one will find a thickening of the peripheral nerves. This condition has the potential to involve other organs including the eyes, nose, testes, and bone. Ulcerated nodules release large numbers of M. leprae bacteria.
