RT Journal Article SR Electronic T1 Polycythaemia rubra vera and hairy cell leukaemia in the same patient: studies on the spleen JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 1312 OP 1315 DO 10.1136/jcp.35.12.1312 VO 35 IS 12 A1 Mufti, GJ A1 Hamblin, TJ A1 Stevenson, FK A1 Fitchett, M YR 1982 UL http://jcp.bmj.com/content/35/12/1312.abstract AB The first association of polycythaemia rubra vera (PRV) and hairy cell leukaemia (HCL) is reported. The secretion by spleen cells in short term culture of IfGλ to the exclusion κ demonstrated that despite aberrant surface marker studies the HCL was a monoclonal tumour of B cells. Chromosomal studies on splenic cells were not able to demonstrate the common clonal origin of the two tumours.
