Adult T-cell Leukemia in a Chilean Resident in Spain: Long-Lasting Remission after 2-Deoxycoformycin Treatment.

We report a patient born in a non-endemic area for human T-lymphotropic virus type I (HTLV-I) infection, in whom an adult T-cell leukemia (ATL) was diagnosed. After the development of acute symptomatic hypercalcemia, treatment with 2-deoxycoformycin was administered. Only mild side-effects were observed, and after treatment a long-lasting complete remission was achieved. The epidemiology of HTLV-I infection and the treatment of ATL are discussed.
