Autoimmune lymphoproliferative sydrome

According to the National Institutes of Health, autoimmune lymphoproliferative sydrome is "a human disease caused by failure of lymphocytes to die once they have finished doing their job. As a result, the spleen and lymph nodes grow large, and immune cells may attack the body's own tissues, a condition known as autoimmunity."[1]
