Adult T-Cell Leukemia and Lymphoma, or ATLL for short, is a cancer of T-cells which can be present in the bloodstream as leukemia, or form masses in lymph nodes as lymphoma. This condition is associated with the HTLV-1 or human T-lymphotropic virus type I, a virus that is part of the retrovirus family. The cancer is most commonly seen in adults from areas where HTLV-1 is endemic, including Japan, West Africa, and the Caribbean. Besides the classic symptoms of leukemia and lymphoma, one high-yield clinical finding is the development of red scaly rashes.
