[Demonstration of Reed-Sternberg cells immunoglobulin production by ultrastructural immunocytochemistry (author's transl)].

Presence of immunoglobulins in the Reed-Sternberg and Hodgkin cells cytoplasm is confirmed by ultrastructural immunoperoxydase methods using serum Fab human antigammaglobulins. Hypothesis proposed by Garvin of an immunoglobulin synthesis by unbound ribosomes seems probable.
