pri·mar·y tu·ber·cu·lo·sis

first infection by Mycobacterium tuberculosis, typically seen in children but also occurs in adults, characterized in the lungs by the formation of a primary complex consisting of small peripheral pulmonary focus with spread to hilar or paratracheal lymph nodes; may proceed to cavitate or heal with scarring or may progress.

primary tuberculosis

the childhood form of tuberculosis, most commonly occurring in the lungs, the posterior pharynx, or, rarely, the skin. Infants lack resistance to the disease and are readily infected and especially vulnerable to rapid and extensive spread of infection through the body. In childhood the disease is usually brief and benign, characterized by regional lymphadenopathy, calcification of the tubercles, and residual immunity. The disease may reactivate later in life. The tuberculin test result will be positive for life. See also tuberculosis.
