Sequential chromosome studies were done on a patient who developed diffuse histiocytic lymphoma (DHL) after a long history of untreated chronic T-cell leukemia. During the indolent phase of her disease, a pseudodiploid lymphocyte population with 3q+ and 14q+ chromosome markers gradually replaced the originally diploid tumor cells. The karyotype of the lymphoma was hypertriploid (70--74 chromoso...

True histiocytic lymphomas (THLs) are rare tumors in which the malignant cells show morphologic and immunophenotypic evidence of histiocytic differentiation. We describe THLs that arose after therapy for one case of T-lineage lymphoblastic lymphoma (LyL) and two cases of acute lymphoblastic leukemia (ALL) (both CD10+, one pre-B phenotype). The lymphoblastic neoplasms were not unusual in any way...
