RT Journal Article SR Electronic T1 Angiofollicular and plasmacytic polyadenopathy: a pseudotumourous syndrome with dysimmunity. JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 1068 OP 1076 DO 10.1136/jcp.33.11.1068 VO 33 IS 11 A1 J Diebold A1 M Tulliez A1 A Bernadou A1 J Audouin A1 G Tricot A1 M Reynes A1 G Bilski-Pasquier YR 1980 UL http://jcp.bmj.com/content/33/11/1068.abstract AB Two cases are reported of an apparently distinct type of immune disorder. Beginning with mild anaemia and widespread massive lymphadenopathy, the disease progressed to a fatal autoimmune type haemolytic anaemia. Serum investigation showed polyclonal hypergamma-globulinaemia and some autoantibodies. Repeat lymph node biopsies in each case showed hyperplasia within B lymphocyte territory (follicular hyperplasia and polyclonal plasmacytosis with IgG predominance) and atrophy of T dependent areas. Dilatation of lymph sinuses, vascular proliferation, and sclerosis were striking features. This appears to be a new entity, and reasons are given for separating this disease from other pseudotumourous lymph node disorders associated with dysimmunity.
