Tumores pulmonares en pediatría

Abstract

In patients under 15 years of age primary lung tumors are infrequent, most thoracic tumors being originated in the mediastinum or the thoracic wall. The great majority of pulmonary masses are non-neoplastic corresponding to inflammatory processes or malformations. Amongst neoplasms metastasis from solid extracraneal tumors are the predominant lesions. Other malignant neoplasms are: bronchial carcinoid, mucoepidermoid carcinoma, pulmonary lymphoma, pleuropulmonary blastoma and metastasis. In the spectrum of benign lesions the following are found: miofibroblastic inflammatory tumor, nodular lymphoid hyperplasia and hamartomas. The diagnosis of primary pulmonary neoplasms is frequently late because of its low incidence, lack of clinical suspicion and the variability of its manifestations. Radiological and tomographical signs are very proteiform and unspecific, representing a great diagnostic challenge.
