C91.5: Adult T-cell lymphoma/leukaemia [HTLV-1-associated]

Adult T-cell lymphoma/leukaemia, often associated with HTLV-1 (Human T-cell Leukemia Virus type 1) is a rare form of cancer that affects the T-cells, a type of white blood cell that plays a crucial role in the immune system. This disease is usually caused by the HTLV-1 virus, which is passed from person to person through contact with contaminated blood, sexual contact, or breast milk from infected mothers. Common symptoms can include skin rash, enlarged lymph nodes, and weakness. Over time, the disease can progress and affect various parts of the body, including the skin, lymph nodes, liver, lungs, and central nervous system. In some cases, individuals may also develop symptoms such as frequent infections, weight loss, and fatigue.
