Tissue necrosis following axillary (armpit) lymph node infection in an HIV (human immunodeficiency virus) patient. Lymph nodes are part of the immune system and are found throughout the body. The nodes filter unwanted substance,such as cancer cells,bacteria and viruses,from the lymph. When the body becomes infected,they swell up. HIV weakens the immune system,making it harder for the patient to fight infection and easier for tissue death (necrosis) to set in. Photographed in Africa,where lack of basic medical services,particularly in rural areas,allows many conditions to progress before treatment can be provided | |
