Tumor fibroso solitario de mediastino anterior adherido a pericardio. Reporte de un caso / Solitary fibrous tumor of anterior mediastinum adhered to pericardium. A case report

Se presenta el caso de un paciente de 82 años, con tumor intratorácico de crecimiento rápido, con aumento progresivo de la disnea, antecedentes de enfermedad coronaria y baja función cardíaca, obesidad y síndrome de apnea de sueño, quien fue sometido a toracotomía y a quien se le diagnosticó un tumor solitario fibroso de la pleura, tumor de muy baja frecuencia, adherido en forma sésil al pericardio, lo cual lo hace aún menos frecuente. Se hace una revisión general de las posibilidades terapéuticas, el diagnóstico histológico y por inmunohistoquímica, así como los criterios de benignidad y malignidad para este tipo de tumor, que son en su mayoría de buen pronóstico.

We present the case of an 82-year-old patient with a rapidly growing intrathoracic tumor, progressive increase in dyspnea, and a history of coronary heart disease and low cardiac function, obesity, and sleep apnea syndrome, who underwent thoracotomy and who was diagnosed with a Solitary Fibrous Tumor of the Pleura, a very low frequency tumor, adhered in sessile form to the pericardium, which makes it even less frequent. A general review is made of the therapeutic possibilities, the histological and immunohistochemical diagnosis, as well as the criteria of benignity and malignancy for this type of tumor, most of which have a good prognosis.

Tumor fibroso solitario gigante de pleura / Giant solitary fibrous tumor of the Pleura

Resumen Objetivo: Reportar el caso de una masa gigante en hemitórax izquierdo de 19 cm de diámetro en un paciente de 59 años que debutó con disnea, tos y dolor torácico, confirmándose por estudio imagenológico. Materiales y Método: Registro clínico de un paciente al cual se le diagnostica tumor fibroso solitario de pleura, siendo intervenido quirúrgicamente para exéresis de la lesión. Resultados: Se realiza toracotomía posterolateral izquierda para exéresis de tumor gigante, requiriendo además, resección de diafragma y pericardiectomía parcial con evolución favorable. Discusión: El tumor fibroso solitario es una neoplasia rara derivada del mesénquima que afecta más comúnmente a la pleura, típicamente bien circunscrita, pediculada, con vasos dentro del pedículo tumoral, pudiendo llegar a ser de gran tamaño, siendo considerados gigantes cuando tienen más de 15 cm de diámetro. Conclusión: El diagnóstico correcto es de vital importancia, ya que con la resección quirúrgica es potencialmente curable. El tratamiento quirúrgico puede efectuarse por toracotomía o videotoracoscopia, dependiendo del tamaño del tumor. A pesar del comportamiento benigno, requiere seguimiento a largo plazo debido a la tendencia a la recidiva.

Aim: To report the case of a 19 cm diameter giant mass in the left hemithorax in a 59-year-old patient who presented with dyspnea, cough and chest pain, confirmed by imaging study. Materials and Method: Clinical record of a patient who was diagnosed with a solitary fibrous tumor of the pleura, undergoing surgery to excise the lesion. Results: A left posterolateral thoracotomy was performed to excise the giant tumor, also requiring resection of the diaphragm and partial pericardiectomy with favorable evolution. Discussion: The solitary fibrous tumor is a rare neoplasm derived from the mesenchyme that most commonly affects the pleura, typically well circumscribed, pedunculated, with vessels within the tumor pedicle, and can become large, being considered giant when they are larger than 15 cm diameter. Conclusión: The correct diagnosis is of vital importance, since surgical resection it a potentially curable treatment. Surgical treatment can be performed by thoracotomy or videothoracoscopy, depending on the size of the tumor. Despite the benign behavior, it requires long-term follow-up due to the tendency to recur.

Tumor fibroso solitario de la pleura / Solitary fibrous tumor of the pleura

El tumor fibroso solitario de la pleura (TFSP) representa una neoplasia benigna de evolución habitualmente silente, hallazgo incidental y heterogeneidad en su presentación. Raramente se malignizan y la sintomatología se relaciona fundamentalmente con el compromiso por compresión de las estructuras vecinas. Su tratamiento es la cirugía. Se describe el caso de un paciente masculino de 49 años con antecedentes de hipertensión arterial, diabetes mellitus y obesidad que consultó al Servicio de urgencias por disnea. Se solicitó tomografía de tórax que evidenció voluminosa masa de densidad de partes blandas en hemitórax izquierdo con desplazamiento del mediastino y descenso del diafragma del mismo lado. La fibrobroncoscopia no evidenció lesión endoluminal. Fue evaluado por Cirugía del Tórax. Se realizó abordaje de la masa mediante toracotomía postero lateral izquierda. El estudio anatomopatológico informó formación tumoral de 25 × 16 × 13 cm, peso de 1905 gr y en la microscopía se describió proliferación celular fibroblástica, células fusiformes de núcleos pequeños ovoides y escaso citoplasma dispuestas en haces desordenados con colágeno interpuesto. La inmunohistoquímica informó vimentina y CD34 positivos. Se realizó el diagnóstico de tumor fibroso solitario de la pleura. La evolución posterior fue buena.

The solitary fibrous tumor of the pleura (SFTP) represents a benign neoplasm of commonly silent evolution, incidental finding and heterogeneous presentation. It rarely becomes malignant and symptoms mainly result from the involvement of neighboring structures due to compression. It is treated with surgery. We describe the case of a 49-year-old male patient with history of arterial hypertension, diabetes mellitus and obesity who consulted the Emergency Services because he was experiencing dyspnea. We requested chest tomography that showed a voluminous soft tissue density mass in the left hemithorax with mediastinal shift and decreased diaphragm on the same side. The fibrobronchoscopy didn't show endoluminal lesion. The patient was evaluated by the Thorax Surgery staff. The mass was treated by means of left posterolateral thorachotomy. The anatomopathological study reported the formation of a tumor of 25 × 16 ×13 cm and 1905 gr, and the microscopy described fibroblast cell proliferation, spindle cells of small ovoid nuclei and very little cytoplasm placed in disorganized bundles with collagen interposition. The immunohistochemistry disclosed positive vimentin and CD34. The patient was diagnosed with solitary fibrous tumor of the pleura, with good subsequent evolution.

Primary Cutaneous Solitary Fibrous Tumor on the Back

Solitary fibrous tumors (SFT) are uncommon mesenchymal tumors. SFT have several synonyms including localized fibrous tumor, benign mesothelioma, localized fibrous mesothelioma, and submesothelial fibroma. SFT usually occur in the pleura or other serosal surfaces, but SFT can also develop in extrapleural areas including the nasal cavity, orbit, retroperitoneum, and pelvis. Cutaneous SFT is extremely rare, and more likely to occur in the head and neck region. Histologically, this tumor can mimic a variety of benign and malignant tumors such as dermatofibroma, dermatofibrosarcoma protuberans, spindle cell lipoma or other mesenchymal tumors. Most cases of SFT show non-aggressive clinical courses, with low recurrence rates. Herein, we describe a case of primary cutaneous SFT which presented with huge mass on the back.

Tumor fibroso de la túnica vaginal / Fibrous tumor of the vaginal tunic

RESUMEN Se presenta el caso de un paciente de 21 años de edad que refiere aumento paulatino del escroto de varios meses de evolución, sin dolor u otros síntomas. Con el objetivo de exponer una lesión benigna paratesticular clasificada como, tumor fibroso de la túnica vaginal, se practicó una escrototomía con toma de biopsia, exéresis de la tumoración y se conservó el testículo. El tejido fibroso fue puesto en evidencia con la biopsia intraoperatoria, posteriormente la histopatología hizo el diagnóstico de tumor fibroso. La orquiectomía es posible evitarla cuando nos encontramos ante lesiones paratesticulares que son benignas en la mayoría de los casos(AU)

ABSTRACT We present the case of a 21-year-old patient who reports a gradual increase in the scrotum of several months of evolution, without pain or other symptoms. In order to expose a benign paratesticular lesion classified as fibrous tumor of the vaginal tunic, a scrototomy was performed with biopsy, excision of the tumor and the testicle was preserved. The fibrous tissue was revealed with the intraoperative biopsy, later histopathology made the diagnosis of fibrous tumor. Orchiectomy can be avoided when we are faced with paratesticular lesions that are benign in most cases(AU)

Tumor fibroso solitario gigante de pleura en paciente joven / Giant Solitary Fibrous Tumor of the Pleura in Young Patient / Tumor fibroso solitário gigante de pleura em paciente jovem

Resumen Introducción : el tumor fibroso solitario de pleura (TFSP) es una patología poco frecuente, corresponde a menos del 5 % de los tumores primarios de pleura, siendo aún más raros los tumores mayores de 15 cm y aquellos en pacientes menores de 35 años, ya que el pico de incidencia es entre los 60 a 70 años con un solo caso reportado en Colombia. Presentación del caso : paciente femenina de 33 años, sin exposición a asbesto o cigarrillo. Consultó por cuadro de disnea de moderados esfuerzos y dolor dorsal derecho. La tomografía axial computarizada (TAC) contrastada de tórax evidenció una gran masa sólida de contornos lobulados que comprometía el 70 % del hemitórax derecho de origen extrapulmonar y que comprimía la aurícula derecha, la inmunohistoquímica de la biopsia percutánea clasificó la lesión como tumor fibroso solitario. Fue llevada a toracotomía posterolateral derecha extendida, donde se encontró un tumor dependiente de la pleura parietal derecha resecado en su totalidad. Histopatología e inmunohistoquímica del producto de resección quirúrgica, compatibles con tumor fibroso solitario de pleura, tamaño 30 x 23 x 16 cm sin características de malignidad. La evolución posoperatoria fue satisfactoria, con un egreso hospitalario temprano. Discusión : en una paciente joven, el TFSP gigante es inusual, posterior a su diagnóstico, y a pesar de tener algunas características que sugerían malignidad: tamaño y origen en la pleura parietal, la resección quirúrgica fue el tratamiento indicado para este tumor, con posterior confirmación histopatológica compatible con tumor benigno.

Abstract Introduction : The solitary fibrous tumor of the pleura (SFTP) is an uncommon pathology. It corresponds to less than 5 % of the primary tumors of the pleura. Even much rare is to find one solitary fibrous tumor, of more than 15 cm in patients younger than 35 years since the incidence peak is between 60 to 70 years. There has been only one case reported in Colombia. Case presentation : The subject of study was a 33-year-old female patient, no exposure to asbestos or cigarette. The chief complaints of the patient were mild dyspnea and right dorsal pain. Thoracic contrast-enhanced computerized tomography showed a large solid mass of lobulated contours that compromised 70 % of the right hemithorax, of extrapulmonary origin compressing the right atrium. Immunohistochemistry of the percutaneous biopsy demonstrated a solitary fibrous tumor. The patient underwent an extended right posterolateral thoracotomy. We found and completely resected a tumor hanging on the right parietal pleura. Histopathology and immunohistochemistry of the product of the surgical resection were compatible with a solitary fibrous tumor of the pleura, 30 x 23 x 16cm in size, and no malignancy. The evolution after surgery was satisfactory with an early hospital discharge. Discussion : In a young patient, a giant TFSP is unusual. After diagnosis and despite having some characteristics that suggested malignancy: its size and origin in the parietal pleura, surgical resection was the appropriate procedure for this tumor, with subsequent histopathological confirmation compatible with a benign tumor.

Resumo Introdução : o tumor fibroso solitário de pleura (TFSP) é uma patologia pouco frequente, corresponde a menos do 5 % dos tumores primários de pleura, sendo ainda mais estranhos os tumores maiores de 15 cm e aqueles em pacientes menores de 35 anos, pois o pico de incidência é entre os 60 a 70 anos com um só caso reportado na Colômbia. Apresentação de caso : paciente feminina de 33 anos, sem exposição a asbesto ou cigarro. Consultou por quadro de dispneia de moderados esforços e dor dorsal direita. A tomografia axial computadorizada (TAC) contrastada de tórax evidenciou uma grande massa sólida de contornos lobulados que comprometia o 70 % do hemitórax direito de origem extrapulmonar e que comprimia a aurícula direita, imuno-histoquímica da biopsia percutânea classificou a lesão como tumor fibroso solitário. Foi levada à toracotomia posterolateral direita estendida, encontrando um tumor dependente da pleura parietal direita ressecado em sua totalidade. Histopatologia e imuno-histoquímica do produto de ressecção cirúrgica, compatíveis com tumor fibroso solitário de pleura, tamanho 30 x 23 x 16cm sem características de malignidade. A evolução pós-cirúrgica foi satisfatória, conseguindo um egresso hospitalar precoce. Discussão : em uma paciente jovem, o TFSP gigante é inusual, posterior a seu diagnóstico e apesar de ter algumas características que sugeriam malignidade; tamanho e origem na pleura parietal, a ressecção cirúrgica foi o tratamento indicado para este tumor, com posterior confirmação hispatológica compatível com tumor benigno.

Tumor fibroso solitario pleural como causa de disnea en un paciente de 53 años / Pleural fibrous solitary tumor as cause of dyspnea in a patient 53 years old

El tumor fbroso solitario pleural es una neoplasia infrecuente originada en las células mesoteliales de la superfcie pleural con una incidencia calculada en alrededor de 2.8 casos por 100.000 pacientes al año [1]; además, representa el 8% de las neoplasias benignas del tórax y 10% de los tumores pleurales [2]. El curso clínico de la mayoría de estos tumores es benigno, raramente pueden recurrir localmente o dar metástasis. Las recurrencias pueden ser tardías, con un período de latencia de hasta 30 años [3], la mayoría de los casos se localizan en la pleura visceral o parietal; además, pueden aparecer en otras áreas tales como peritoneo, mediastino, meninges, pulmón, tiroides, parótida, órbita, nariz y fosas nasales. Clínicamente este tumor es asintomático y suele diagnosticarse de manera casual en una radiografía de tórax.

Solitary fibrous tumor is a rare neoplasia characterized by the proliferation offusiform cells of mesenchymal origin accounting for at least 2% of all soft tissue tumors.In this present case, the initial diagnosis was salivary gland tumor because of the location in the hard palate. Histologically, the tumor was composed by conjunctive tissue with proliferation of oval and fusiform cells. The immunohistochemical analysis was positive for CD34 and CD99. The lesion was treated by surgical resection. The clinical, imaging, histological and immunohistochemical data are discussed in this study

Giant solitary fibrous tumor of the pleura: A case report and literature review / 中南大学学报(医学版)

Solitary fibrous tumor (SFT) is a derived mesenchymal tumor from spindle cells, mostly occurred in the pleura. To analyze the clinical features of the SFT, data for a patient with SFT that involved in the pleura were retrospectively analyzed by assisted thoracoscope in the Affiliated Hospital of Zunyi Medical College in August 2015. The male patient was 45 years old, who showed the main clinical symptoms of chest pain, cough, sputum, and dyspnea. Large amount of right pleural effusion, chest space-occupying lesions were found by chest CT, suggesting a malignant tumor with metastasis at the 2nd and 3rd right rib. Immunohistochemical results showed: CD34 (+), cytokeratin (-), cytokeratin 5/6 (-), calretinin (-), epithelial membrane antigen(-), mesothelial cell (-), vimentin (++), Wilm's tumor-1 (+), Bcl-2 (+), CD56 (-), CD99 (+), desmin (-), and thyroid transcription factor-1 (-). It was diagnosed as SFT at right side wall layer pleura. SFT is a rare disease and it may occur at any site in the body. It lacks characteristic clinical symptoms and can be asymptomatic, or displays symptoms such as cough, chest pain, dyspnea, and hemoptysis. SFTs can only be conclusively diagnosed based on histopathologic and immunohistochemical characteristics of the tumor, and they are mostly benign. The main treatment for SFTs is the complete surgical resection. The prognosis for this disease is relatively good.

Tumor fibroso solitario del hígado: revisión del conocimiento actual Solitary fibrous tumor of the liver: updating knowledge / Solitary fibrous tumor of the liver: updating knowledge

El tumor fibroso solitario del hígado es infrecuente. Hasta la fecha, se han reportado menos de 50 casos en la literatura científica inglesa, la mayoría de los cuales se comportaron como tumores benignos. El objetivo del presente artículo es actualizar el conocimiento sobre este tumor porque, debido a su rareza, la presentación clínica, el estudio, el tratamiento y el pronóstico no son bien conocidos. Habitualmente, no produce sintomatología o es inespecífica y su comportamiento a largo plazo es incierto; no obstante, en algunos casos, se comporta agresivamente como un sarcoma de mal pronóstico. Actualmente, solo el tratamiento quirúrgico puede ofrecer una oportunidad terapéutica para estos pacientes. Debido a la falta de conocimiento sobre el comportamiento a largo plazo de estos tumores supuestamente benignos y a la falta de tratamiento médico específico, se sugiere el seguimiento metódico a largo plazo para garantizar la supervivencia de los pacientes operados por un tumor fibroso solitario del hígado.

Solitary fibrous tumors of the liver (SFTL) are uncommon tumors. To the present day less than 50 cases has been reported in the scientific English literature, most of which behaved as benign tumors. The present article has the main purpose of updating knowledge on SFTL because, due to its rarity, its clinical presentation, study, treatment and prognosis, are not well known. The clinical presentation, radiologic study, surgical treatment, immunohistochemical study and prognosis are updated and comprehensively discussed. The SFTL is an uncommon neoplasm. The clinical presentation is habitually indolent and its behavior is uncertain. In some cases, the SFTL acts as an aggressive sarcoma with poor prognosis. Currently, only surgery offers a therapeutic opportunity for these patients. Due to the lack of current knowledge on the long-term behavior of supposedly benign SFTLs and to the lack of specific therapies, methodical long-term follow-up is essential to ensure the survival of patients treated for SFTL.

Solitary fibrous tumor of the pleura: 3 case reports / fibroso solitário de pleura: relato de 3 casos

Summary Introduction: solitary fibrous tumor of the pleura (SFTP) is a rare tumor arising from mesenchymatous cells in submesothelial pleural tissue which, unlike mesothelioma, is not related to asbestos or smoking. Methods: report of four patients who underwent surgical treatment for giant SFTP and review of the pertinent literature. Results: of the four patients operated, two presented symptoms including cough, chest pain and feeling of compression, whereas the other two subjects were asymptomatic. All patients underwent complete surgical resection by wide posterolateral thoracotomy, and surgical specimens removed with minimum bleeding. None of the cases required complementary lobectomy or segmentectomy. All tumors were histologically benign. Conclusion: complete resection of the lesion is the treatment of choice in all SFTP cases. Prognosis of the benign lesion is excellent, although close follow-up is necessary. In the rarer, more aggressive forms, treatment may be complemented by adjunctive chemotherapy or radiotherapy, the benefits of which have yet to be confirmed. .

Resumo Introdução: o tumor fibroso solitário de pleura (TFSP) é um tumor raro com origem nas células mesenquimatosas do tecido pleural submesotelial, que, ao contrário do mesotelioma, não tem relação com asbesto ou tabagismo. Método: relato de caso de quatro pacientes submetidos a tratamento cirúrgico para TFSP gigante e revisão da literatura pertinente. Resultados: dos quatro pacientes operados, dois apresentaram sintomas como tosse, dores no peito e sensação de compressão enquanto os demais foram assintomáticos. Todos os pacientes foram submetidos à ressecção cirúrgica total por toracotomia posterolateral ampla, sendo os espécimes cirúrgicos removidos com mínimo sangramento. Em nenhum dos casos houve necessidade de lobectomia ou segmentectomia complementar. Todos os tumores eram histologicamente benignos. Conclusão: a ressecção total da lesão constitui o tratamento de escolha em todos os casos de TFSP. O prognóstico de lesões benignas é excelente embora o acompanhamento seja necessário. Nas formas mais raras e agressivas, o tratamento pode incluir quimioterapia ou radioterapia adjunta, cujos benefícios ainda não foram confirmados. .

Solitary fibrous tumor of the pleura mimicking pleural effusion

Solitary fibrous tumor of the pleura is a rare mesenchymal neoplasm of fibroblastic origin and represents less than 5% of primary tumors of the pleura. There are few reports in the literature about this disease, therefore the data on its presentation and management are derived from reports and retrospective analysis of case series from referral centers. In this report, we describe a case of a patient who presented this diagnosis during hospitalization, and following we briefly review the published literature of this pathology...
