[Prolymphocytic leukemia of T-cell type. Clinical, cytological, cytochemical and immunological studies (author's transl)].

Prolymphocytic leukaemia (PL) is a rare variant of lympho-proliferative disorder, defined by Galton [21], which differs clearly from CLL by clinical, haematological and immunological features. Nevertheless like CLL, PL appears to represent predominantly a B cells monoclonal proliferation and cases of T-PL are rare. We report about another case of PL which was found to have T-lymphocyte characteristics and some clinical and immunological particularities.
