title: [History of 2 cells in T cell lymphomas and leukemias: the cerebriform Lutzner cell in Sézary syndrome and the polylobulated or polypetaloid cell in acute T cell lymphoma/leukemia].
abstract: In normal blood, there appears to be two similar but different subsets of T-lymphocytes present: (1) the cerebriform or convoluted Sézary-syndrome Lutzner cell, which may give rise to cutaneous T-cell lymphoma; (2) the polypetaloid or lobated acute T-cell lymphoma/leukemia (ATLL) cell, which may give rise to ATLL. Both cell types can be differentiated by their characteristic nuclear shapes.
