The origin and nature of the lymphoid cell component of Warthin's tumor are controversial. The present report described the application of immunologic study to the Warthin's tumor lymphocytes. Not only subpopulation of T and B cells and numbers of surface immunoglobulins were comparable to those of other lymph nodes.
These findings, in conjuction with morphologic observations, support the concept that the lymphoid component of Warthin's tumor is derived from a pre-existing lymph node.
