Glands in the axilla or groin, depending upon the site of injection, are almost invariably enlarged to the point of being easily palpable. However, we could find no report in the literature of large regional glands following such immunization. For this reason, two cases of marked axillary adenitis, due in all probability to the injection of antigens for immunization, are reported.
