Abstract
A primary complex (PC) is a localised lesion formed due to the reaction of the body tissues to the first exposure to tubercle bacilli. The lung is the most frequent site of primary infection. Inhaled bacilli get implanted in the periphery of the lung where a "tubercle" is formed. Initially the response consists of an accumulation of polymorphs, followed by macrophages and 4-6 weeks later lymphocytes appear in large numbers. The bacilli also spread to the draining hilar lymph nodes where the same changes occur. The lesion at the point of entry and that in the node together form the primary complex.
