C91: Lymphoid leukaemia

C91.3: Prolymphocytic leukaemia of B-cell type

Prolymphocytic leukaemia of B-cell type is a rare and aggressive type of leukemia, a blood cancer that starts in the bone marrow, the soft inner part of your bones where new blood cells are made. Specifically, this condition impacts a type of white blood cell known as B cells that fight off infections. In this condition, the body produces an excessive amount of abnormal B cells, known as prolymphocytes. These abnormal cells overwhelm the healthy cells, disrupting their normal function. Common symptoms include fatigue, weakness, weight loss, swollen lymph nodes, an enlarged spleen or liver, and repeated infections. This disease typically progresses rapidly, often leading to severe and life-threatening complications. Prolymphocytic leukaemia isn't contagious; it is caused by changes in the DNA of the cells and is not transmitted from person to person.
