secondary tuberculosismedical dictionary

Tuberculosis found in adults and characterised by lesions near the apex of an upper lobe, which may cavitate or heal with scarring without spreading to lymph nodes; theoretically, secondary tuberculosis may be due to exogenous reinfection or to reactivation of a dormant endogenous infection.

Synonyms: adult tuberculosis, postprimary tuberculosis, reinfection tuberculosis.
