Adult T-cell lymphoma (ATL) is a neoplastic disease associated in 80%
of cases with HTLV-I (Human T Lymphotropic virus type I) infection. 1-
2% of HTLV-I carriers may develop the disease during their lives. In o
ur country, the prevalence of HTLV-I infection is about 1%. We report
a 72 y.o. woman HTLV-I positive, confirmed by Western-Blot, presenting
with massive adenopathies, cutaneous tumor involvement, acute course
and showing Reed-Sternberg cells (RSCs) in lymph node biopsy. The resp
onse to chemotherapy was poor, with the patient dying seven months aft
er diagnosis. ATL and Hodgkin's disease (HD) are discussed highlightin
g that RSCs are not pathognomonic of HD though in their absence such d
iagnosis can not be made. RSCs are found in other benign and malignant
disorders and it is especially important to differenciate HD from the
other processes in order to dispense the appropriate treatment. This
is the first case of ATL with RSCs reported in Chile. Hence, in our co
untry we suggest systematic determination of the presence of HTLV infe
ction when histopathology is compatible with HD and Non Hodgkin Lympho
