RESUMO
BACKGROUND: Pulmonary complications, such as airway leak syndrome, are common in preterm neonates; however, bronchial rupture is a rarely seen phenomenon. CASE PRESENTATION: In this case, we present a preterm newborn who developed pneumomediastinum and pneumothorax. The pneumothorax persisted, despite placement of a thorax tube, requiring a thoracotomy to detect and treat the bronchial rupture. CONCLUSION: Physicians should have a high suspicion of bronchial rupture in patients with persistent air leak syndrome, even after thorax tube placement and continuous negative pressure implementation.

In children and adolescents with chest pain and dyspnea, pneumonia, pleural effusion, and empyema are the frequent causes in the differential diagnosis. Malignant tumors of the chest wall are rare and most originate from the ribs. In children, the most frequent malignant tumor of the rib is Ewing's sarcoma. Osteosarcomas of the rib are very rare. Osteosarcoma has a predilection for rapidly growing long bones including the femur, tibia and humerus in adolescents. In this paper, we present an adolescent girl who presented with chest pain and dyspnea with osteosarcoma that originated from the rib and extended to the right hemithorax.
RESUMO
A cytological diagnosis is essential for a definitive diagnosis in children who have paratracheal lesions. Thirteen pediatric patients were biopsied using cervical mediastinoscopy. Age, gender, preoperative diagnosis, and postoperative biopsy results and complications were reviewed. Five patients had mediastinal lesions residuing or recurring after chemotherapy for either Hodgkin disease or non-Hodgkin lymphoma. In 2 of these patients, the diagnosis was recurrent disease. Among the 8 patients presenting with a paratracheal mass or enlarged lymph nodes, histopathologic diagnosis showed tuberculosis in 3 children, Hodgkin disease in 2 children, and histiocytosis X and non-Hodgkin lymphoma 1 patient in each. This study shows that cervical mediastinoscopy gave 100% correct diagnosis for mediastinal residual malignancies or uncommon forms of mycobacterium tuberculosis with paratracheal masses.
