title: T-prolymphocytic leukemia with circulating carrot-like cells.
abstract: A case of T-prolymphocytic leukemia leading to rapid demise of a 67-year-old man is reported. He presented with multiple skin lesions and splenomegaly. A unique feature was that a proportion of circulating leukemic cells assumed bizarre shapes, resembling carrots. The leukemic cells expressed the T-cell markers T11, T8 and Dako-T2, and the natural killer cell markers NKH1, Leu7 and Leu 11b.
