RESUMEN
The solitary fibrous tumor (SFT) is usually described as a lesion arising from the pleura. Rarely, it has been described in the parapharyngeal space (PS). This study aims to report two cases of SFT in the PS and to perform a literature review on this topic. Two patients undergoing surgical resection of a SFT in the PS, were reported. A literature review on SFT of the PS, was also performed. Two patients were analyzed. Both patients underwent surgical resection, followed by adjuvant radiotherapy, for SFT arising from the PS. The postoperative course was uneventful and both patients recovered well after the procedure. No recurrences were diagnosed during the followup. SFT of the PS is an infrequent entity. Surgical resection is the most used treatment, and adjuvant radiation should be considered in patients with recurrence risk factors or distant metastases.

El espacio parafaríngeo es una región donde puede surgir un amplio espectro de tumores, que son poco frecuentes y comprenden solo el 0,5 al 1,5% de las neoplasias de cabeza y cuello. Generalmente, son hallazgos y suelen presentarse como masas asintomáticas. Incluye neoplasias primarias, extensión directa de regiones adyacentes y enfermedad metastásica. La literatura describe múltiples patologías e histologías que pueden surgir de esta zona, entre ellas, tenemos los tumores fibrosos solitarios, que son un espectro de neoplasias mesenquimatosas fibroblásticas de histogénesis incierta, que generalmente involucran la pleura. Son lesiones muy poco frecuentes y su localización parafaríngea es excepcional, siendo su primer reporte en la literatura en 1993. Se presenta el caso de un tumor fibroso solitario del espacio parafaríngeo evaluado en nuestro centro, con su enfrentamiento diagnóstico, resolución quirúrgica y seguimiento respectivo, con el objetivo de presentar esta patología poco frecuente a nuestros colegas y contribuir al conocimiento médico.
The parapharyngeal space is a region where a wide spectrum of tumors can arise, which are rare and comprise only 0.5% to 1.5% of head and neck neoplasms. They are generally findings and usually present as asymptomatic masses. Includes primary neoplasms, direct extension from adjacent regions, and metastatic disease. The literature describes multiple pathologies and histologies that can arise from this area, among them, we have solitary fibrous tumors, which are a spectrum of fibroblastic mesenchymal neoplasms of uncertain histogenesis, which are generally the pleura. It is a very rare lesion and its parapharyngeal location is exceptional, being its first report in the literature in 1993. We present the case of a solitary fibrous tumor of the parapharyngeal space evaluated in our center, with its diagnos- tic confrontation, surgical resolution and respective follow-up, with the aim of presenting this rare pathology to our colleagues and contributing to medical knowledge.

Spinal solitary fibrous tumour (SFT) is an uncommon tumour with few cases reported in the literature. It rarely originates at the craniocervical junction. To our knowledge, only eight cases of spinal SFT located at the craniocervical junction have been reported in the literature. We presented a patient with a craniocervical junction SFT and discussed its clinical presentation, radiological features, pathology, management and outcome. This was the first patient reported in the literature with a recurrent craniocervical junction SFT treated with Gamma Knife radiosurgery. The treatment reduced the tumour volume by more than 85% within 12 months.

We present the case of a 71-year-old man with a history of type 2 diabetes mellitus manifesting abdominal pain, weight loss, dyspnea on small efforts, muscle weakness, and left subcostal swelling. Associated with this, he developed frequent episodes of syncope, diaphoresis, and night sweats, during which blood glucose levels below 50 mg/dL and improvement were documented after the administration of hypercaloric beverages or intravenous dextrose. Abdominal computed tomography revealed the presence of a tumor of approximately 20 cm dependent on the left adrenal gland. Histopathological diagnosis of a solitary retroperitoneal fibrous tumor was obtained, confirmed by immunohistochemistry.

BACKGROUND Solitary fibrous tumors (SFTs)/hemangiopericytomas (HPCs) are mesenchymal tumors commonly found in middle-aged patients, usually localized to thoracic pleurae. Spinal tumor involvement is rarely seen, and its imaging findings are largely inconsistent because of the rarity of these cases. We present a case report of a 9-month-old girl with a rare intraspinal tumor with histologic evidence of SFT/HPC, but no STAT6 nuclear immunoreactivity. CASE REPORT A 9-month-old girl, born at term with good prenatal care, presented to the emergency room with regression of developmental milestones. The patient was in good health until 2 months, when she developed decreased spontaneous leg movements. Physical exam revealed diffuse muscular atrophy, with no deep tendon reflexes, sensation, or spontaneous movements of the lower extremities. Computed tomography and magnetic resonance imaging showed a heterogeneous irregular mass filling the lumbosacral spinal canal, extending through the neural foramina to the prevertebral/perivertebral and presacral regions. The tumor was biopsied and referred to the National Institutes of Health for consultation and the diagnosis of SFT/HPC was confirmed on the basis of its histologic features, despite the fact that the tumor was negative for STAT6 immunoreactivity. CONCLUSIONS Although the tumor histology was consistent with SFT/HPC, it was negative for STAT6 nuclear immunoreactivity, which is unusual and may exclude the diagnosis. To our knowledge, this is the youngest patient to present with a spinal SFT with these features.

El tumor fibroso solitario es raro. Si bien su localización más frecuente es la pleura, han sido informados algunos casos de ubicación retroperitoneal. Es difícil diferenciarlo imagenológicamente de otras neoplasias, por lo que casi siempre el diagnóstico es histológico. Dado que los tumores fibrosos solitarios tienen presentaciones clínicas muy diversas, una mejor compresión de la ubicación y sus características imagenológicas ayudaría a abreviar la lista de diagnósticos diferenciales. Comunicamos un tumor fibroso solitario de localización retroperitoneal cuyo diagnóstico fue confirmado por examen histológico.
The solitary fibrous tumor is uncommon. Even though it frequently locates in the pleura, a few cases have been reported in the retroperitoneum. Differentiation from other neoplasms is difficult, and therefore the diagnosis is always attained through histological examination. Although solitary fibrous tumors have variable clinical behaviors, a better comprehension of the location and its imaging characteristics would help to decrease the list of differential diagnoses. We report a solitary fibrous tumor located in the retroperitoneum whose diagnosis was confirmed by histological examination.

El tumor fibroso solitario (TFS) es una neoplasia mesenquimal de células fusiformes infrecuente descrita inicialmente en la pleura pero con localización reconocida en otros sitios. El TFS de la glándula tiroides (TFST) es aun más raro. Se describe el caso de una mujer de 65 años de edad, con masa cervical de crecimiento progresivo, a tal punto que ya la masa se hacía notable en parte inferior de su cuello, siendo este el único síntoma narrado. La paciente presentaba una gran masa tiroidea en el lóbulo derecho con extensión intratorácica. Se practicó hemitiroidectomia derecha (paciente tenia historia previa de resección del lóbulo tiroideo izquierdo por lesión benigna) Total, además de toracotomía endoscópica por la extensión de la masa la cual en la tomografía contrastada, se originaba en el lóbulo tiroideo derecho y descendía paralelo a la columna dorsal desplazando a la tráquea y el esófago. La patología reportó un tumor de 15 centímetros, con células fusiformes y patrón de crecimiento hemangiopericítico sin pleomorfismo, atipia, mitosis o necrosis. Luego de practicar diferentes estudios y marcadores tumorales, de todos estudios fueron positivos CD34, Bcl2, CD99 y vimentina. Se diagnosticó tumor fibroso solitario de glándula tiroides. El nervio vago derecho fue lesionado en la cirugía, actualmente está en terapia de voz. Al momento actual casi seis meses luego de su cirugía, no se documenta recidiva tumoral.
Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm initially described as spindle cells in the pleura but recognized location elsewhere. The TFS thyroid gland (TFST) even infrequent. A case of a 65 years old woman with progressive growth of a right cervical mass without associated symptoms described other than cosmesis is described . The patient had a thyroid mass in the right lobe with intrathoracic extension. A right Hemi thyroidectomy and thoracotomy for the extent of the mass was performed. Pathology reported a 15 cm tumor with spindle cell and growth pattern hemangiopericitic without pleomorphism, atypia, mitosis or necrosis. Immunohistochemistry was positive for CD34, Bcl-2, CD99 and vimentin, making the diagnosis of solitary fibrous tumor of thyroid gland. The patient's right Vagus nerve was injured intraoperatively and she is currently under voice therapy. Currently now, almost six months after her surgery she is free of disease.

En los últimos años la comunidad científica internacional ha dedicado considerables recursos a la investigación y desarrollo de sistemas de diagnóstico asistidos por ordenador, utilizados por los médicos en el proceso de diagnóstico. Se ha prestado especial atención en algunas áreas médicas, como las especialidades oncológicas, por los altos índices de mortalidad provocados por algunas enfermedades como el cáncer de pulmón. El diagnóstico temprano de este padecimiento puede reducir en gran medida estos indicadores y mejorar la calidad de vida de los pacientes. El objetivo que se pretende con el desarrollo de esta investigación, es la selección adecuada de un algoritmo de clasificación, para ser utilizado en la fase que lleva el mismo nombre como parte de un sistema de diagnóstico asistido por ordenador para la clasificación de nódulos pulmonares solitarios. Para la selección adecuada del algoritmo de clasificación, se realiza un experimento utilizando las herramientas Weka v3.7.10 y Matlab 2013. Para determinar cuál de las técnicas estudiadas arroja mejores resultados de rendimiento, se utilizó el mismo conjunto de datos para las fases de entrenamiento, prueba y validación del clasificador, disponible en la base de datos internacional The Lung Image Database Consortium Image Collection(AU)
In recent years the international scientific community has devoted considerable resources to research and development of systems for computer-aided diagnosis used by physicians in the diagnostic process. Special attention has been provided in some medical areas, such as oncology specialties, by high mortality rates caused by some diseases like lung cancer. Early diagnosis of this condition can greatly reduce these indicators and improve quality of life of patients.The objective pursued with the development of this research is the proper selection of a classification algorithm, to be used in the phase that has the same name, as part of a system of computer-aided diagnosis for classification of solitary pulmonary nodules. For the selection of the appropriate classification algorithm, an experiment was performed using the tools Weka v3.7.10 and Matlab 2013. To determine which of the techniques studied produces better performance results, the same data set was used for the phases of training, testing and validation of the classifier, available in the international database The Lung Image Database Consortium Image Collection(AU)

Fat-forming solitary fibrous tumor (SFT) is a rare variant of solitary fibrous tumor, a mesenchymal fibroblastic neoplasia with a particular branching hypervascular pattern. This tumor is usually classified as benign and only very few fat-forming SFTs with malignant histologic features have been reported. We report a histologically malignant fat-forming solitary fibrous tumor in a 61-year-old man, located in his neck. Ultrasonography examination was first performed showing a heterogeneous lesion, predominantly hyperechoic, with sound beam attenuation, containing two hypoechoic solid nodules. Magnetic resonance imaging and computed tomography examinations demonstrated a heterogeneous and predominantly adipose mass, containing post contrast enhancing solid nodules and thin septations. Treatment consisted of total removal of the lesion. Histologically, the tumor showed hypercellularity, numerous mitoses and cytological atypia, fulfilling the criteria for malignancy. The patient had no metastasis. This rare tumor may be confused with other fat-containing lesions on imaging examinations, mainly liposarcoma.

Solitary fibrous tumor (SFT) was first described in the pleura by Lietaud in 1767; later in 1870, Wagner described the localized nature of this type of tumor and Klemperer and Rabin classified pleural tumors into two types: diffuse mesotheliomas and localized mesotheliomas. Recent years have seen the redefinition of this neoplasm, due to better technology; it is now proven that this neoplasm may have multiple different extrapleural origins including the head and neck regions. This diversity of locations is related to the particular mesenchymal histogenesis of SFT which allows its development from very unusual sites such as the salivary glands (SGs). In this particular site, this neoplasm is very infrequent and most of reported cases refer to benign disease, with just one case informed so far of primary malignant SFT.

BACKGROUND: Solitary fibrous tumor is the second primary malignancy of the pleura and can reach up to 39 cm in diameter; however, to be referred to as 'giant' it must occupy at least 40% of the affected hemithorax. Although this tumor usually shows a benign behavior, malignancy criteria have been described. The aim of the study was to assess the initial evaluation, diagnostic procedures, surgical management, treatment outcome, and prognosis. METHODS: We performed a descriptive, observational, longitudinal, and retrospective study from 2002 to 2006 on patients who underwent surgery with a diagnosis of giant solitary fibrous tumor of the pleura. RESULTS: Six patients were included; 83.3% were females. Mean age was 48 years. All patients were symptomatic, mainly dyspnea, cough and chest pain; 66.7% were left-sided. Preoperative angiography and embolization were performed in 83.3% cases with successful surgical resection. The predominant blood supply was derived from the internal mammalian artery. Intraoperative complication rate was 17%. A vascular pedicle was found in 66.7%. The largest lesion was 40 cm in diameter and weighed 4500 g. Only one case showed high mitotic activity. Mean follow-up to date is 14 months. CONCLUSIONS: Symptomatology found was consistent with previous reports but in higher percentages. Accurate diagnosis is critical because surgical resection involves a potential cure; however, long-term follow-up is mandatory. Preoperative embolization is recommended due to tumor size.
