1. Immunology of may be compared to those obtained previously using separated cells and immunofluorescence. Domagala et a14 reported a mean of 80O2% rosette forming lymphocytes in pleurisy and in effusions due to pleural infiltration by chronic lymphocytic leukaemia cells;Boccato, P.; Saran, B.; Pasini, L.; Briani, G.; Pasini, P.;Acta Cytol,1978
2. T and B lymphocyte enumeration in the diagnosis of lymphocyte-rich pleural fluids;Domagala, W.; Emeson, E.E.; Koss, L.G.;Acta Cytol,1981
3. Cytological diagnosis of lymphoma in serous effusions;Al, Spriggs; RI, Vanhegan;J Clin Pathol,1981
4. Immunohistological identification of lymphocyte subsets and accessory cells in human hyperplastic tissues'2 and may reflect the migration into effusions of lymphoid cells from tissues lining serous cavities. Our results are in keeping with the single case of sarcoidosis reported by Groman et al,3 in which lymph nodes;Ralfkiaer, E.; Plesner, T.; Lange Wantzin, G.; Thomsen, K.; Nissen, N.I.; Hou-Jensen, K.;Scand J Haematol,1984
