Retroperitoneal Effusions in Renal Regions

Abstract

of lymphosarcoma Hynes (1939) found the marrow normal in six, but there were 61 per cent. lymphatic cells in the remaining patient's marrow. In a series of over 100 patients I= have found lymphocytosis of the marrow in only two conditions besides lymphatic leukaemia; these are glandular fever and aplastic-type anaemias. In glandular fever the lymphoid cells in the marrow are increased-in one patient there were 55 per cent.-but if these are discounted all the other normal varieties of cells are present in their normal proportions. In aplastictype anaemia there may be a marrow lymphocytosis of 70 per cent. or more; but this is only relative, and the raised percentage of lymphocytes is due to the decrease of all the other marrow cells.
