ABSTRACT

Melanotic schwannoma (MS) is a rare and infrequent subtype of schwannoma characterized by cytoplasmic deposits of melanosomes (melanin). Unlike the other schwannomas, it could have malignant transformation. Due to distinctive characteristics and atypical behavior from classic schwannomas subtypes, MS were renamed and reclassified as "melanocytic malignant neural sheath tumor" in the 5th ed. of the World Health Organization's classification of central nervous system tumors in 2021. We present two cases of MS that underwent complete surgical resection.


El schwannoma melanótico (SM) es una variante rara e infrecuente caracterizada por el depósito citoplasmático de melanosomas (melanina). A diferencia de las otras variantes de schwannomas, tienen capacidad de malignización. Por poseer características y comportamiento distintos al resto de los schwannomas, fue reclasificado como "tumor maligno melanocítico de la vaina neural" en la 5ta edición de la clasificación de los tumores del sistema nervioso central de la Organización Mundial de la Salud en 2021. Presentamos dos casos de SM de ubicación mediastinal en los que se realizó una resección quirúrgica completa.

ABSTRACT

Clear cell "sugar" tumor of the lung is a rare benign tumor arising from perivascular epithelioid cells (PECs). They belong to a group of mesenchymal neoplasms called PEComas. Although widely presumed as benign, due to their rich vascular stroma they are usually avid for the different types of contrast agents used in imaging studies, mimicking a malignant lesion. We report the case of a 66-year-old man in whom a solitary pulmonary nodule was discovered during oncological staging for an adenocarcinoma of the prostate who underwent an anatomical pulmonary segmentectomy. The final pathology result was a perivascular epithelioid cell tumor (pulmonary PEComa or clear "sugar" cell tumor).


Los tumores de células claras "de azúcar" (CCTL) son lesiones benignas muy infrecuentes. Forman parte de un grupo de neoplasias mesenquimales denominadas PEComas que se originan de las células epiteloides perivasculares. Por su rico estroma vascular, suelen tener avidez por los distintos tipos de contrastes utilizados en los estudios de diagnóstico por imágenes, simulando lesiones de estirpe maligna. Presentamos el caso de un paciente de 66 años con hallazgo de un nódulo pulmonar durante la estadificación oncológica por adenocarcinoma de próstata al que se le realizó una segmentectomía pulmonar anatómica. El resultado definitivo de anatomía patológica fue tumor de células epiteloides perivasculares (PEComa pulmonar o tumor de células claras "de azúcar").

ABSTRACT

Resumen Las neoplasias epiteliales del timo (NET) son tumores infrecuentes. El manejo inicial de las mismas se basa en el análisis de la resecabilidad del tumor en los estudios por imágenes, siendo la resección completa el tratamiento estándar para cualquier estadio. El objetivo principal fue evaluar la supervivencia global y la supervivencia libre de enfermedad de los pacientes con diagnóstico de NET sometidos a tratamiento quirúrgico. El objetivo secundario fue comparar la supervivencia global de acuerdo al tipo de resección quirúrgica, el estadio de Masaoka-Koga y subtipo histológico. Estudio observacional descriptivo realizado en el Hospital Británico de Buenos Aires desde 2004 a 2020. Se incluyeron 42 pacientes operados de tumores en mediastino anterior con diagnóstico histopatológico definitivo de NET. Treinta y nueve eran timomas y 3 carcinomas tímicos. La cirugía realizada en todos los pacientes fue una timectomia total. La mediana de seguimiento fue de 63.5 meses (RIQ 32-97.5). La supervivencia global estimada a los cinco y diez años fue del 87% (95% IC, 0.69-0.95) y 78% (95% IC, 0.5-0.92), respectivamente. La supervivencia libre de enfermedad estimada a cinco y diez años fue del 90% (95% IC, 0.74-0.96). Los pacientes a los que se le realizó una resección completa y que tenían estadios tem pranos de Masaoka-Koga presentaron una supervivencia global superior en comparación con las resecciones incompletas y estadios avanzados (p = 0.0097 y p = 0.0028, respectivamente). Al contar con un bajo número de pacientes en el grupo de carcinomas tímicos, no pudimos sacar conclusiones en cuanto a supervivencia entre éstos y los timomas.


Abstract Thymic epithelial tumors are a group of rare neoplasms of the mediastinum. When resectable, complete resection is considered the gold standard for any stage. The primary endpoint was to evaluate overall survival and disease-free survival of patients with thymus epithelial tumors who underwent surgical treatment. The secondary endpoint was to evaluate and compare the overall survival according to: resection type (complete vs. incomplete), Masaoka-Koga stage and tumor histology according to WHO classification. This is a descriptive observational study from January 2004 to December 2020, in which 42 patients with a postoperative histopathological diagnosis of thymic epithelial tumours were included. Thirty-nine were thymomas (92.9%) and 3 were thymic carcinomas (7.1%). In all patients a total thymectomy was performed. The median follow-up was 63.5 months (IQR 32-97.5). The estimated overall survival at five and ten years was 87% (95% CI, 0.69-0.95) and 78% (95% CI, 0.5-0.92), respectively. Estimated disease-free survival at five and ten years was 90% (95% CI, 0.74-0.96). Patients who underwent complete resection and with early Masaoka-Koga stages had superior overall survival compared to incomplete resections and advanced Masaoka-Koga stages (p = 0.0097 and p = 0.0028, respectively). We found no differences in terms of survival between histological subtypes due to a low number of patients in the thymic carcinoma group.

ABSTRACT

OBJECTIVE: Mediastinal nodal staging in lung cancer is essential to determine treatment strategy and prognosis. There are controversies as to whether a mediastinal negative result in PET-CT may spare the invasive staging of the mediastinum. The main endpoint is to evaluate the negative predictive value (NPV) of PET-CT in non-small cell lung cancer (NSCLC) clinical stage IB-IIA without clinical nodal involvement. The secondary endpoint is to evaluate the prevalence of mediastinal and hilar nodal affection in this population. METHODS: We performed an observational descriptive study from January 2010 to January 2020, including 76 patients with clinical stage IB-IIA, who underwent pulmonary resection with systematic nodal sampling (pre-determined lymph node stations based on tumour location) for primary NSCLC. Clinically, nodal involvement was defined as any lymph node greater than 1 cm in the short axis on a CT or with metabolic uptake greater than 2.5 SUV on PET-CT. The prevalence of nodal metastases was recorded. RESULTS: Fifty six patients had clinical stage IB and 20 had clinical stage IIA. Mean tumour size was 3.74 ± 0.5 cm. Lobectomy was the resection procedure most frequently performed. Of the 76 patients with clinical N0 by PET-CT who underwent surgical resection, 10 (13.1%) were upstaged to pN1 and none were upstaged to pN2. NPV of PET-CT for overall nodal metastasis was 87% (95% CI: 0.79-0.94). NPV of PET-CT for N2 metastasis was 100%. CONCLUSION: PET-CT might be an alternative to invasive mediastinal staging in patients with NSCLC clinical stage IB-IIA who are surgical candidates. Further prospective multi-institutional studies are necessary to verify the external validity of our study.

ABSTRACT

Resumen El síndrome del opérculo torácico se refiere a una serie de signos y síntomas que se producen por la compresión del paquete vásculo-nervioso en la unión costo-clavicular. El síndrome de Paget-Schroetter (SPS) se define como la trombosis primaria, espontánea o de esfuerzo de la vena subclavia. Las vías de abordaje quirúrgicas tradicionales utilizadas para descomprimir el opérculo torácico son la trans axilar y las claviculares (supra e infra). El objetivo del estudio fue describir nuestra experiencia en la resección de la primera costilla por videotoracoscopía (VATS). Este es un estudio descriptivo observacional utilizando una base de datos prospectiva con análisis retrospectivo desde enero de 2017 a marzo de 2020. Se incluyeron 9 pacientes con diagnóstico de SPS en los que se resecó la primera costilla por VATS. En un paciente el procedimiento fue bilateral por presentar trombosis espontánea en ambas venas subclavias. De los 9, 6 eran mujeres. La edad media fue de 30.7 ± 10.7 años. La estadía hospitalaria media fue de 3.1 ± 0.5 días. Uno fue re-operado por hemotórax. No se detectaron recurrencias en el seguimiento a mediano-largo plazo. La resección de la primera costilla por VATS es un procedimiento seguro y factible. La misma, a diferencia de los abordajes tradicionales, puede ser resecada bajo visión directa de todos los elementos del opérculo torácico. Sin embargo, esta técnica requiere un manejo avanzado en cirugía toracoscópica.


Abstract Thoracic outlet syndrome (TOS) refers to a number of signs and symptoms that arise from compression of the neurovascular bundle at the costoclavicular junction. Paget-Schroetter syndrome is defined as the primary, spontaneous or effort thrombosis of the subclavian vein. The supraclavicular and trans-axillary approaches are currently the most commonly used for first rib resection. The aim of this article was to describe our experience in a minimally invasive approach (VATS) of first rib resection for primary venous thoracic outlet and the associated outcomes. This is a descriptive observational study using a retrospective analysis of a prospective database from January 2017 to March 2020. Nine patients underwent video thoracoscopic first rib resection due to PagetSchroetter syndrome (one bilateral procedure). Ten thoracoscopic first rib resections were performed. There were 6 female and 3 male patients, with a mean age of 30.7 ± 10.7 years. The mean length of hospital stay was 3.1 ± 0.5 days. No complications were recorded intraoperatively. One patient had to be re-operated because of hemothorax. There were no recurrences in a follow-up of at least 12 months. VATS resection of the first rib is a safe and feasible procedure and can be performed under direct vision of thoracic outlet elements. However, the technique requires experience with thoracoscopic surgery. The outcomes associated with our technique are comparable with the outcomes related to other current standards of care.

ABSTRACT

OBJECTIVE: Long-term survival of patients who undergo surgical resection of isolated adrenal metastasis instead of nonsurgical treatment has shown higher values than those described for stage IVA. The primary endpoint was to evaluate overall survival (OS) of patients with single adrenal metastasis from non-small cell lung cancer (NSCLC), who underwent surgical treatment. The secondary endpoint was to evaluate and compare the OS and disease-free survival (DFS) according to: pathological lung tumour size, histology, lymph node involvement, type of metastasis at the time of diagnosis and laterality of the metastasis according to the primary lung tumour. METHODS: From August 2007 to March 2020, 13 patients with isolated adrenal gland metastasis were identified. We performed a descriptive observational study including patients with diagnosed single adrenal gland metastasis of resectable primary lung cancer and no history of other malignant disease. Clinical data obtained included patient demographics, metastases characteristics, laterality of the metastasis, time between surgeries, length of follow-up, survival status, pathological lung tumour size, histology and lymph node involvement. The variables analysed were OS and DFS. RESULTS: Median global OS was 31.9 months (interquartile range (IQR), 19.1-51.4). The 2- and 5-year OS estimated was 54% (95% CI: 29.5%-77.4%) and 36% (95% CI: 13.4%-68.1%), respectively. In patients with NSCLC without mediastinal lymph node involvement, we obtain a median OS of 40 months (IQR, 27.4-51.4) and a 2- and 5-year OS estimated of 75% (95% CI: 43.2%-92.2%) and 50% (95% CI: 18.7%-81.2%), respectively. Recurrence was detected in five patients with a median DFS of 11.9 months (IQR, 6-34.2). CONCLUSION: The resection of the adrenal metastasis should be considered if the primary lung cancer is resectable. Presence of mediastinal lymph node involvement should be ruled out through invasive staging of the mediastinum before performing adrenal and lung surgery. Proper selection of patients who would benefit from surgery is essential to obtain better survival results.

ABSTRACT

Antecedentes: Existen múltiples técnicas de esofagectomía mini-invasiva (EMI). Su gran heterogeneidad hace que los meta análisis no den resultados concluyentes y que se requieran series con técnicas estandarizadas. Existen pocas experiencias publicadas de esofagectomías subtotales con anastomosis intratará cicas realizadas totalmente por vía mini-invasiva. No existen publicaciones de EMI en nuestro país. Objetivo: Analizar los resultados iniciales de una serie consecutiva de EMI con anastomosis intratorácica. Lugar de aplicación: Hospital Británico de Buenos Aires. Diseño: Estudio observacional retrospectivo. Población: 34 pacientes operados de esofagectomías totalmente mini-invasivas de 2009 a 2011, con más de 6 meses de seguimiento. Método: Se excluyeron los casos híbridos (abordajes combinados mini-invasivos y convencionales). Se evalúa una serie inicial de EMI, analizando las subtotales con anastomosis intratorácicas realizadas por abordaje totalmente laparoscópico y toracoscópico. Resultados: De las 34 EMI, 26 fueron con anastomosis intratorácica. No hubo conversiones. El promedio de ganglios resecados fue de 26,1. La morbilidad total fue del 38,2%, de las cuales la morbilidad mayor en subtotales fue del 19,2%. Se registró una mortalidad (2,9%) debida a hemorragia post colocación de stent endoscópico. El 85% de los pacientes presentó sobrevida libre de enfermedad, con seguimiento de 21 meses. No hubo recidivas locales ni implantes tumorales en sitio de trocares. Conclusiones: La EMI con anastomosis intratorácica es una técnica segura en recuperación y morbilidad posoperatoria. Permite manejo tipo fast track con tiempos cortos de internación. Este abordaje posibilitó linfadenectomías radicales con bajo impacto respiratorio.(AU)


Background: múltiple techniques of esophagectomy are mini-invasive (MIE). Its great heterogeneity makes the meta-analyses do not give conclusive results and series with standardized techniques may be required. There are few published experiences of esophagectomies subtotals with anastomosis performed entirely by the via mini-invasive intrathoracics. There are no publications of MIE in our country. Objective: To evalúate the initial results of a consecutive series of MIE with intrathoracic anastomosis. Setting: Hospital Británico de Buenos Aires. Design: retrospective observational study Population: 34 esophagectomies-operated patients completely mini-invasive from 2009 to 2011, with more than 6 months of follow-up. Method: the hybrid cases (combined approaches mini-invasive and conventional) were excluded. An initial series of EMI with the subtotals intrathoracic anastomosis by totally laparoscopic and thoracoscopic approach was evaluated. Results: Of the 34 EMI, 26 were with intrathoracic anastomosis. There were no conversions. The average number of nodes resected was 26.1. Total morbidity was 38.2, of which higher subtotals morbidity was the 19.2. There was a (2.9) mortality due to bleeding post endoscopio stent placement. The 85 patients presented survival free of disease with followup of 21 months. There were no local recurrences or implants in trocar site. Conclusions: The EMI with intrathoracic anastomosis is a safe technique with advantages in recovery and post-operative morbidity. It allows type fast track with short hospital stay times. This approach enabled radical lymphadenectomy with low respiratory impact.(AU)

ABSTRACT

Antecedentes: la producción de un episodio de neumotórax recidivado luego de avenamiento pleural sugiere la existencia de una lesión (bulla o ampolla) que genera aerorragia haciéndose necesaria su exéresis quirúrgica lo que tradicionalmente se hacía por toracotomía. El advenimiento de la cirugía, torácica videoasistida ha hecho posible extirpar esas lesiones sin toracotomía. Objetivos: describir la técnica quirúrgica de bullectomía videotoracoscópica y comparar sus resultados con aquellas obtenidas mediante toracotomía. Lugar de aplicación: Hospital comunitario terciario afiliado a Universidad. Diseño: retrospectivo no randomizado. Población: 326 pacientes de ambos sexos (edad 16-92) a los que se trató en 405 episodios de neumotórax espontáneo. Método: se utilizó un algoritmo estratégico para indicar la bullectomía videotoracoscópica en 130 pacientes. Los recidivados de ésta serie se los comparó con otra histórica de 176 bullectomías por toracotomía realizada en otra Institución. Resultados: la bullectomía videotoracoscópica es el tratamiento de elección para tratar el neumotórax recidivado o el neumotórax inicial asociado a situaciones de riesgo

ABSTRACT

This is a report of a 61 year old man who was admitted at the Intensive Care Unit because of massive hemoptysis and respiratory failure. Four years before he had had an aortic dissection type A, and at that time an aortic valve, ascending aorta and aortic arch replacement, had been carried out. A thorax CT scan showed an aneurysm of the ascending aorta. A bronchoscopy was normal. In the angiography, a collateral of the left mammary artery was identified as the cause of bleeding and was subsequently embolized. After the procedure, the patient had a new episode of massive hemoptysis, and surgery was recommended. During surgery, the diagnosis of aortobronchial fistula was confirmed but the patient died during the intervention.
