Leukapheresis in a patient with Sézary syndrome

A patient with Sézary syndrome refractory to cytotoxic agents underwent leukapheresis on the Aminco continuous flow centrifuge. Five procedures were performed over a 15-day period. A total of 6.9 X 10(9) cells were removed. The patient's skin lesions and lymphadenopathy regressed. Repeated removal of the buffy coat by leukapheresis has not resulted in thrombocytopenia. It is concluded that cytapheresis may be effective in this clinical condition even when the peripheral leukocyte count is normal.
