[Cytoplasmic immunoglobulins in lymph node cells in angioimmunoblastic lymphadenopathies]

The content of immunoglobulins in cells of lymph nodes from 5 patients with angioimmunoblastic lymphadenopathy was studied by the immune peroxidase technique. A large number ofplasma cells containing immunoglobulins was found in the affected lymph nodes. The presence of both kappa and lambda chains within these cells proved their polyclonal nature. Immunoblasts and lymphoid cells contained no cytoplasmic immunoglobulins.
