primary tuberculosis


primary tuberculosis
pulmonary tuberculosis when a person is first infected, usually seen in children or immunocompromised adults. It is often asymptomatic, with simply a positive result on a tuberculin test. In children there may be exudation (see exudative t.), with the primary complex consisting of a parenchymal pulmonary lesion and a corresponding lymph node focus.
