Duan Bo, deputy chief physician of the Seventh Department of Hunan Provincial Chest Hospital, introduced that primary tuberculosis in children is the primary infection that occurs after Mycobacterium tuberculosis invades the lungs for the first time. It is pediatric tuberculosis The main type of tuberculosis accounts for 85%-90% of the total number of various types of pulmonary tuberculosis in children.

Primary pulmonary tuberculosis includes primary syndrome and bronchial lymph node tuberculosis. The former is composed of primary lung lesions, local lymph node lesions and lymphangitis connected to the two. The latter is mainly swollen lymph nodes in the chest. The primary tumor in the lungs may be small in scope, or obscured by the mediastinal shadow and cannot be detected by X-ray, or the primary tumor may have been absorbed, leaving only locally swollen lymph nodes, so it is clinically diagnosed as bronchial lymph node tuberculosis. The two types merge into one type, primary pulmonary tuberculosis.

Intrapulmonary lymphoid tuberculosis can easily invade the trachea, cause damage to the bronchi, and cause severe clinical symptoms. After the formation of primary pulmonary tuberculosis, whether the lesions progress or are absorbed depends on many factors, such as age and close contact with patients with open pulmonary tuberculosis. Such as rapid growth and development and high nutritional requirements, it is easy to develop progressive tuberculosis . Such as miliary tuberculosis, tuberculous lobar pneumonia, with cavitation, caseous pneumonia, etc.

In the vast majority of children, primary pulmonary tuberculosis changes for the better. The inflammation around the lesion shrinks and calcification appears within a few months. It takes about a year to see calcification in the chest.
