title: A case of small-cell Sézary's syndrome with null-cell features.
abstract: A case of the small-cell variant of Sézary's syndrome (SS) is reported in which the SS cells lacked the surface-marker characteristics of both T- and B-cells. In particular, the SS cells failed to form E-rosettes even with a sensitive technique using 2-amino-ethylisothiouronium bromide (AET)-treated sheep red blood cells. The significance of these findings is briefly considered in relation to the existing literature.
