The syndrome of abnormal chromatin clumping in leucocytes: clinical and biological study of a case.

The authors report the clinical and biological findings of a case of a rare haematological malignant entity, morphologically characterised by a bizarre nuclear abnormality in granulocytes, consisting of exaggerated chromatin clumping and apparent fragmentation of the nucleus, with a loss of segmentation. They emphasize the coexistence of proliferative and dysplastic characteristics as a distinctive marker of this disorder and suggest it may represent a distinct rare morphological entity among the atypical chronic myeloid leukaemias, Ph1 and ber negative.

Reactive hemophagocytosis in Ki-l positive large cell lymphoma: a case study.

A case of large cell lymphoma presenting with hemophagocytic syndrome is reported. The clinicopathological findings suggested a diagnosis of malignant histiocytosis, but on the basis of immunohistological studies Ki-l lymphoma was diagnosed. Neoplastic cells expressed activation antigens such as HLA-DR, IL 2R, T10 and Ki-l, and showed high proliferative activity, but were devoid of T and B cell markers. The high percentage of reactive macrophages found in the bone marrow and lymph node probably reflected the release of lymphokines by the tumor population. The patient was treated with aggressive chemotherapy and is in complete remission at 8 months from diagnosis.
