ABSTRACT

BACKGROUND: In children, acute affectation of the thorax is presented during pleuropulmonary infection, bronchopulmonary malformation and malignant tumors. We had the opportunity to treat patients with malignant tumors in the thorax and we present our findings. CLINICAL CASES: We studied three patients with the diagnosis of pleuropulmonary blastoma. All patients were being treated with surgical resection for the neoplasm and one patient received pneumonectomy. Diagnosis of blastoma was confirmed histologically and one had positive histochemical markers to vimentin and S-100. Only one patient died. CONCLUSIONS: 1. Different cellular types of pleuropulmonary blastoma were confirmed using histochemical markers. 2. The pediatric surgeon facing a case of a child with acute thorax affectation due to pleuropulmonary blastoma must undertake thoracotomy on an urgent basis.


ANTECEDENTES: en los niños, la afección aguda del tórax se manifiesta concomitante con infección pleuropulmonar, malformaciones broncopulmonares y tumores torácicos malignos. Tuvimos la oportunidad de tratar a pacientes con neoplasia maligna, lo que nos motivó a comunicarla. Casos clínicos: se estudian y reportan los casos de tres pacientes con diagnóstico de blastoma pleuropulmonar. Todos se trataron quirúrgicamente mediante resección del tumor en dos pacientes, en uno fue necesaria la neumonectomía. Los estudios histológicos demostraron que se trataba de un blastoma pleuropulmonar con anaplasia y otro resultó positivo para el marcador tumoral de vimentina y S-100. Solo hubo un fallecimiento. CONCLUSIONES: los diferentes tipos celulares que forman el blastoma pleuropulmonar se ratifican con la aplicación de marcadores histoquímicos. Ante un paciente pediátrico con afección aguda del tórax por blastoma pleuropulmonar, el cirujano pediatra tendrá que practicar una toracotomía de urgencia.
