ABSTRACT

El blastoma pleuropulmonar corresponde a una neoplasia primaria de pulmón, exclusiva de la edad pediátrica, poco frecuente y de características agresivas. La edad de diagnóstico varía entre 1 mes y 12 años. No se identifica una distinción de sexos. Se localiza en la pleura o el pulmón. Suele presentarse como dificultad respiratoria, con o sin neumotórax, dolor torácico y fiebre, por lo que es mal diagnosticada como neumonía. Radiológicamente, suele hallarse una masa de gran tamaño cercana a la pleura en la base pulmonar derecha sin broncograma aéreo. Cuenta con tres tipos histológicos: tipo I (quístico), tipo II (mixto), tipo III (sólido). Su tratamiento incluye resección y quimioterapia multimodal. El tipo I tiene un pronóstico favorable, pero los tipos II y III tienen mal pronóstico. Se presenta un caso de blastoma pleuropulmonar en una niña de 2 años, con énfasis en su diagnóstico clínico-radiológico.


Pleuropulmonary Blastoma corresponds to a malignant primary lung disorder, exclusive of pediatric age, infrequent and of aggressive characteristics. Age on diagnosis is 1 month-12 years. Rates per sex are equal. It can be found inside pleura or lungs. Respiratory distress associated or not with pneumothorax, chest pain and fever are classical clinical signs. These symptoms could be misdiagnosed as pneumonia. Radiologically, a large mass near the pleura at the base of the right lung without air bronchogram is its most common form. It has three histological types: type I (cystic), type II (mixed) and type III (solid). Its treatment requires tumor excision and multimodal chemotherapy. Pleuropulmonary Blastoma type I has good prognosis; type II and III variants have lower survival. We report a 2-year-old girl, pointing to the clinical-radiological diagnosis.

ABSTRACT

INTRODUCCIÓN: El blastema pleuropulmonar (BPP) es la neoplasia primaria maligna más común de los pulmones en la infancia. Se presenta con mayor frecuencia en niños entre 1 y 4 años, con sínto mas respiratorios. Han sido definidos tres tipos por histopatología (tipo I, II y III), relacionados con sobrevida y pronóstico. OBJETIVO: Reportar el primer caso de un paciente con un BPP que se presentó como una deformación de la pared torácica. CASO CLÍNICO: Paciente de un año de vida que se presentó con una deformidad de la pared torácica a los 10 meses de edad. El estudio imagenológico reveló una gran masa quística en el hemitórax derecho. No desarrolló sintomatología respiratoria hasta el ingreso hospitalario. Se realizó una lobectomía superior derecha y la biopsia confirmó un BPP tipo I. Se trató con resección quirúrgica y realización periódica de imágenes torácicas como seguimiento. CONCLUSIONES: Se reporta el caso de un BPP que se manifestó con deformidad torácica, forma de presentación no descrita previamente en la literatura. El BPP es un cáncer poco frecuente que debe ser considerado en el diagnóstico diferencial de lesiones quísticas pulmonares, sobre todo en la edad pediátrica. Reconocerlo como un tumor maligno en vez de una anomalía del desarrollo, es determinante para que el paciente sea sometido a resección quirúrgica, terapia adyuvante y seguimiento apropiado.


INTRODUCTION: Pleuropulmonary blastema (PPB) is the most common primary malignancy of the lungs in childhood. It occurs more frequently in children between one and four years of age, and respiratory symptoms are a common manifestation. Three types have been defined (type I, II and III), which are related to survival and prognosis. OBJECTIVE: To report the first case of a patient with a PPB who presented with a chest wall deformity. CASE REPORT: One year old male patient who had a chest wall deformity at ten months of age. Imaging revealed a giant cyst in the right hemithorax. He did not develop respiratory symptoms until hospital admission. A right upper lobectomy was perfor med and the biopsy confirmed a type I pleuropulmonary blastoma. He was considered successfully treated with complete surgical excision and routine follow-up with thoracic imaging is conducted. CONCLUSIONS: PPB is a very rare cancer that needs to be considered in the differential diagnosis of cystic lung diseases in children. The recognition of this lesion as a malignant tumour rather than a developmental cystic malformation is vital so the child can receive complete excision and appropriate follow-up care.

ABSTRACT

El blastoma pleuropulmonar es un tumor pulmonar raro de la infancia, que puede manifestarse con lesiones quísticas o sólidas, como un hallazgo radiológico o con clínica respiratoria. Presentamos el caso de un niño de 2 años de edad que consultó en su primer cuadro obstructivo con imagen sospechosa de malformación pulmonar en el lóbulo superior izquierdo en la radiografía y la tomografía de tórax. Se realizó cirugía, que evidenció una malformación quistica en el segmento ápico posterior del lóbulo superior izquierdo. Recibimos el informe de anatomía patológica con diagnóstico de blastoma pleuropulmonar tipo I. Comenzó el seguimiento por Oncología e inició el tratamiento con ciclofosfamida y vincristina, con buena tolerancia.


Pleuropulmonary blastoma is a rare lung tumor of childhood that can occur with cystic or solid lesions, as a radiological finding with or without respiratory symptoms. We report the case of a 2 year old toddler in his first pulmonary obstructive episode with suspected toracic malformation of the left upper lobe in his chest x-ray and tomography. Surgery was performed showing cystic malformation of the left upper lobe. We received the pathology report with diagnosis of type I pleuropulmonary blastoma. He began follow-up with Oncology initiating treatment with cyclophosphamide and vincristine, well tolerated.

ABSTRACT

Pulmonary blastoma is a rare but aggressive malignancy of the lung comprising epithelial and mesenchymal elements that resemble fetal lung tissue. This report described a case of an 18-year-old male who presented with cough and weight loss for a month. Computed tomography (CT) of the thorax revealed a large mass with mixed solid and cystic lesions on the right side of chest along with pleural effusion and mediastinal lymphadenopathy. Massive debulking was performed followed by chemotherapy. A biphasic pulmonary blastoma was diagnosed on histopathology.

ABSTRACT

En neonatología, las masas torácicas generalmente responden a anomalías congénitas del aparato respiratorio. Comprenden un extenso número de patologías que pueden comprometer el desarrollo de laringe, tráquea, bronquios, parénquima pulmonar, diafragma o pared torácica. El diagnóstico, en la mayoría de los casos, se efectúa en el período prenatal mediante ecografía. El resto se diagnostica por la clínica, difcultad respiratoria en el recién nacido, o es un hallazgo radiológico en el transcurso de la vida. Presentamos el caso de un recién nacido de término con diagnóstico prenatal de "masa pulmonar" con imágenes quísticas en su interior. Al examen físico solo presentó disminución de la entrada de aire en base derecha. Se realizaron diferentes estudios por imágenes para caracterizar mejor la lesión y estudiar su extensión. Al quinto mes de vida, el paciente fue sometido a tratamiento quirúrgico y quimioterápico. El estudio anatomopatológico de la pieza quirúrgica arrojó como diagnóstico "blastoma pleuropulmonar" (BPP), tumor intratorácico maligno, muy poco frecuente, que aparece casi exclusivamente en niños menores de 7 años.


Thoracic masses in neonates usually respond to congenital anomalies of the respiratory system. They comprise a large number of diseases that can compromise the development of larynx, trachea, bronchi, pulmonary parenchyma and diaphragm or chest wall. Diagnosis is carried out during prenatal period by ultrasound in most cases. In others, respiratory distress is diagnosed during post-birth examination or later as a radiological fnding. We present the case of a full term newborn with prenatal diagnosis of cystic "lung mass". Physical examination was unremarkable except for decreased breath sounds on the right lung. Different image studies were carried out to characterize the lesion. The patient underwent surgery and chemotherapy at ffth month of life. Pleuropulmonary blastoma diagnosis was confrmed by pathological study of the surgical specimen. This is a rare intrathoracic malignant tumor, appearing almost exclusively in children less than 7-years-old.

ABSTRACT

The pleuropulmonary blastoma is an aggressive primary lung tumor. Is most frequent in paediatric population, and there are a few cases reported worldwide. It consists of embrionary primitive mesenquimal tissue, and is different of the adult Pulmonary Blastoma. The clinical presentation can be missed by other prevalent diseases or may be an accidental diagnosis. The outcome following diagnosis is poor, overall for types ii and iii, with bad response to surgery and quimiotherapy, high rates or recurrence to more aggressive forms (eg. BPP type i to type ii o iii). This report describes the clinical picture of a two years old preschool child with aggressive BPP. We reviewed the actual literature about this topic.


El blastoma pleuropulmonar (BPP), es un tumor agresivo primario de pulmón. Afecta sobre todo en la edad pediátrica, habiendo sido reportado pocos casos a nivel mundial. El BPP consiste de tejido mesenquimal primitivo embrionario, de características diferentes al blastoma pulmonar del adulto. La presentación clínica suele confundirse con otras patologías frecuentes o puede ser incidental. La sobrevida luego del diagnóstico es pobre, sobre todo para los tipos ii y iii, con poca respuesta a la quimioterapia- cirugía, y alta frecuencia de recaídas a formas más agresivas. Se describe el caso de una pre-escolar de 2 años, con diagnóstico de BPP, que presentó una evolución clínica agresiva, se realizó la revisión de la literatura sobre los principales tópicos concernientes a esta patología.

ABSTRACT

Pleuropulmonary blastoma (PPB) is a rare embrionary mesenchymal neoplasm but is recognized as the most common pulmonary malignancy of childhood. It may present metastasis to the brain and also be indicative of other neoplasms in affected individuals or in their relatives. Being such a rare disease, it is considered a difficult diagnosis to be made. A 3-year-old female presented with fever and respiratory distress. At first, she had been treated for pneumonia with antibiotics for 14 days in another hospital with no response. Computed tomography (CT) scan showed a right lung/mediastinal mass. The patient was referred to our institution and a new CT-scan evidenced a complex mass of irregular borders, cystic areas and solid projections, along with a right pneumotorax. The mass was biopsied and hematoxylin-and-eosin (HE) stained histological sections showed a neoplasm composed of small and round cells with hyperchromatic nuclei and scant cytoplasm. The immunohistochemical profile demonstrated positivity for desmin, myogenin and Myo-D1, suggesting the diagnosis of rhabdomyosarcoma. After two weeks of hospitalization, the patient was clinically stable and initiated the first chemotherapy cycle. Surgical resection of the mass was performed and the HE slides demonstrated a neoplasm composed of anaplastic and condrossarcomatous cells with extensive necrosis. The correlation of clinical data, radiological and morphological features were conclusive of a PPB type II. The recognition and diagnosis of this entity is of great importance due to its clinical and prognostic particularities.

ABSTRACT

Pleuropulmonary blastoma (PPB) is a rare malignant dysontogenetic neoplasm primarily affecting children and is characterized histologically by a variably mixed blastematous and sarcomatous patterns. We herein report a very exceptional adult case of PPB. A 21-yr-old male patient presented with a left chest pain of two weeks' duration. A computed tomography scan revealed a large, multicystic tumor occupying the left lower hemithorax, leading to the impression of a ruptured mediastinal cystic teratoma. A thoracotomy for resection of the tumor was performed. On histologic examination, the tumor consisted of cystic walls and associated solid lesions which showed undifferentiated blastemal tissues with focal fibrosarcomatous and rhabdoid features. Immunohistochemically the tumor cells only showed diffuse strong positivity for vimentin. The histologic findings corresponded to a type II PPB. The authors suggest that PPB, especially of type I or II, should be included in the radiologic differential diagnosis of mediastinal cystic neoplasms in a young adult.

ABSTRACT

A three-and-half-year-old boy presented with recurrent chest infections, fever and weight loss of three month duration not responding to antibiotics. The chest X-ray and CT scan revealed a large well-circumscribed mass in right upper thorax with collapse of right upper lobe. A preoperative diagnosis could not be made even after fine needle aspiration cytology. Thoracotomy and right upper lobectomy was done and the biopsy report was an inflammatory pseudotumor. The child remained well for three months after which his symptoms and the mass recurred. The histopathology slides were reviewed and revealed a biphasic malignant tumor suggestive of Pulmonary Blastoma (PB). Patient received four cycles of chemotherapy followed by re-exploration. The recurrent tumour could only be excised partly and the child succumbed to persistent shock postoperatively. The final histopathological diagnosis was confirmed as PB. Primary pulmonary neoplasms in children are rare and of these PB which is even rarer, constitutes less than 15%. The report highlights that the lack of familiarity with this entity still causes error in the diagnosis of PB.

ABSTRACT

El blastoma pulmonar es una entidad esporádica en niños, siendo un tumor raro, con malignidad primaria para el pulmón y la pleura. Se presenta el caso de un preescolar masculino de tres años de edad cuyo cuadro clínico se manifestó por dolor abdominal, fiebre pérdida importante de peso, ataque al estado general y dificultad respiratoria, diagnosticándose en hospital de segundo nivel como neumonía y derrame pleural. Se discuten las características clínicas y el abordaje diagnóstico en relación a la literatura. Conclusión: nuestro caso demuestra la dificultad para establecer el diagnóstico sin el apoyo del tratamiento quirúrgico. La tomografía computada sugiere la extensión del tumor y la invasión mediastinal, pero es la toracotomía la que de hecho demuestra la posibilidad de resecarse si no existe compromiso mediastinal. Aunque es un tumor con baja frecuencia, las decisiones terapéuticas del blastoma pulmonar son difíciles, sobre todo si tomanos en cuenta que la quimioterapia y radioterapia posteriores al acto quirúrgico, aún están en el plano de la discusión
