When ficoll purified peripheral blood lymphocytes were treated with fluorescein conjugated lectins from lentils (LCH), castor beans (RCA) and phaseolus coccineus beans (L-and E-PHA) for 15 min and the percentages of the cap forming cells were examined, the values of leukemic lymphocytes were reduced compared to the values obtained with normal lymphocytes. The reduction was more than half in patients with acute and chronic myelogenous leukemia and immunoblastoma, it was only one quarter in patients with chronic lymphocytic leukemia, Hodgkin's disease and lymphosarcoma. The lowest number of cap forming cells was found in lymphoblasts of established lymphoblastoid cell lines. The four different lectins showed nearly the same capacity in the induction of caps. After successive binding, the different lectins showed cocapping on the lymphocyte surface.

A case of sinus histiocytosis with massive lymphadenopathy in a boy of 13 with multiple subcutaneous tumor-like formations 0.5 to 2.5 cm in diameter is described. The general condition of the patient was not changed despite the 7-month course of the disease. Mild anemia and increased ESR were observed. Microscopically the formations presented massive "dense" infiltrates of lymphoid, plasma cells, and histiocytes-macrophages with foci of fibrosis and xanthomatosis. Since the morphological picture of sinus histiocytosis with massive lymphadenopathy may to some extent imitate the substrate of some tumor diseases of the hemopoietic and lymphoid tissues (malignant histiocytosis, histiocytosis X, lymphogranulomatosis, lymphosarcoma), their differential diagnosis is presented.
