OBJECTIVE: To investigate clinical and pathological features of lung lesions in children. METHODS: Clinical manifestations, radiologic imaging, histopathological features and immunohistochemical results were analyzed in 215 cases of lung lesions in children. RESULTS: A total of 215 cases of lung lesions in children aged 0 day to 13 years (average age of 27.2 months and the median age of 18.0 months) were selected, including 137 male and 78 female patients with a male to female ratio of 1.76:1.00. The incidence of congenital lung disease was higher in patients of less than 1 year old than those of over 1 year old age, and the difference of the two groups was statistically significant (P = 0.004). 142 cases had acquired lung diseases, and 73 cases had congenital bronchopulmonary dysplasia. Lung abscess was the most common lesion seen in 86 cases (40.0%), including 1 case of fungal abscess. Congenital pulmonary airway malformation (CPAM) was the second most common, seen in 44 patients (20.5%), including 20 cases of type 1, 18 cases of type 2 and 6 cases of type 4 CPAM. Pulmonary sequestration was found in 25 cases (11.6%) including 14 cases of intralobar type and 11 cases of extralobar type. Two cases of extralobar pulmonary sequestration showed simultaneous CPAM2 type 2 lesion. Other lesions included tuberculosis (13 cases, 6.0%), emphysema (12 cases, 5.6%), interstitial pneumonia (7 cases, 3.2%), pulmonary hemorrhage (6 cases, 2.8%), bronchogenic cyst (4 cases, 1.9%), bronchiolitis obliterans (2 cases, 0.9%), idiopathic pulmonary hemosiderin deposition disease (2 cases, 0.9%) and 1 cases of lung non-specific changes. 13 cases of neoplastic lesions (6.0%) were found, of which 11 cases were primary tumors (5.1%), including inflammatory myofibroblastic tumor in 5 patients (2.3%), pleuropulmonary blastoma in 5 cases (1 case of type I, 2 type II and 2 type III) and 1 case of mucoepidermoid carcinoma (0.5%) and 2 cases of metastatic tumors (hepatoblastoma and Wilm's tumor, 0.9%). CONCLUSIONS: Infectious diseases are the most common lung diseases in children. Congenital bronchopulmonary dysplasia is the most common in children of less than 1 year old. Malignant lesions are rare.
