Abstract
Thirty cases of mycobacterial lymphadenitis have been accumulated. By culture 7 have proven to be caused by Myco. tuberculosis, 13 by unclassified mycobacteria. Clinical differentiation has been attempted with strong probability that accurate separation of lymphadenitis caused by human organisms from that caused by unclassified mycobacteria can be accomplished. Precisely, a negative history of contact with tuberculosis, large reactions to unclassified skin test antigen with concomitant weakly positive or negative tuberculin skin test, the absence of a tuberculin band on agar diffusion in the face of reaction to unclassified antigens, and the absence of active pulmonary parenchymal disease in the preschool age group (predominantly age 1-3 years) point toward an unclassified mycobacterial etiology. A positive history of contact with tuberculosis, large reaction to tuberculin with concomitant small or negative unclassified mycobacterial skin tests, the presence of a tuberculin band on agar diffusion, and the presence of active pulmonary parenchymal disease favors Myco. tuberculosis as the etiologic agent. The treatment of both human and unclassified mycobacterial disease of lymph nodes has been attended with good results and relatively uncommon recurrence.
