Ghon's complex

Ghon's complex is a lesion seen in the lung that is caused by tuberculosis. The lesions consist of a calcified focus of infection and an associated lymph node. These lesions are particularly common in children and can retain viable bacteria, so are sources of long-term infection and may be involved in reactivation of the disease in later life. In approximately 95% of cases, development of cell-mediated immunity controls the infection.
