Cellular immunity in 64 patients with Hodgkin's disease was studied during diagnosis before any treatment. The functional deficiency of the thymodependent lymphocyte was demonstrated in vivo by skin tests and, in vitro, by the test of inhibition of leucocyte migration to phytohemagglutininin and spontaneous rosette formation, to sheep red cells. This deficiency correlates with the clinical spread and the histological severity. The relationship between skin anergy and biological tests was found. The epicutaneous test using croton oil possesses non-specific inflammatory activity. It is negative this test is negative, skin reactivity to specific antigens is reduced. The croton tests help interpretation of skin responses to specific antigens and thus assessment of the immune state.
