Fibroma mole, ou pólipo fibroepitelial, é uma lesão de proporções geralmente reduzidas, de cor hiperpigmentada ou igual à da pele, localizando-se frequentemente na face, pescoço, tronco e regiões intertriginosas. É um tumor classificado como benigno e pode acometer tanto homens quanto mulheres em idade reprodutiva e depois da quarta década de vida. Ocorre principalmente em obesos, diabéticos e durante a gestação. Com menor frequência, podem alcançar dimensões que excedem 5 cm. Seu crescimento pode ser lento ou rápido e comumente são assintomáticos, mas podem promover sangramentos por conta de ulcerações decorrentes de traumas repetidos. Apresentamos neste relato um fibroma mole, gigante, de localização vulvar, com 11 cm de comprimento, 11 cm de largura e 5 cm de espessura, pesando 500 g.

Giant soft vulvar fibroma is a fibroepithelial polyp lesion with generally reduced proportions, with a hyperpigmented color or similar to that of the skin, frequently located on the face, neck, trunk and intertriginous regions. It is a tumor classified as benign, can affect both men and women, of reproductive age and after the fourth decade, mainly obese, diabetic and during pregnancy. However, less frequently, they can reach dimensions that exceed 5 cm, may have a slow or accelerated evolution. They are commonly asymptomatic, but bleeding may be present due to ulcerations resulting from repeated trauma. In the current study, we describe a giant soft fibroma with a vulvar location measuring 11 cm in length, 11 cm in width, 5 cm in thickness and weighing 500 grams.

Lipofibromatous hamartoma (LFH) is a rare fibrofatty tumor of adipocytes within peripheral nerves, affecting mainly children. It typically presents as a palpable mass surrounding the nerves of the upper limbs, causing pain and neurological deficits in the affected nerve distribution. We report the case of a child with a 2-years presentation of a mass in the right wrist associated with pain and paresthesia, who underwent investigation with magnetic resonance imaging (MRI). It showed thickening of the median nerve with spaghetti-like appearance associated with lipomatous tissue in a coaxial cable-like pattern, both features characteristic of LFH. This case illustrates the importance of MRI in the differential diagnosis of limb masses in the pediatric population.

Abstract The authors present a case of fibroma of the tendon sheath with intra-articular location in the knee, more specifically in the infrapatellar fat; with this specific location, this is the fourth case described of an entity that rarely affects large joints. Clinical and epidemiologi-cal aspects, but especially the imaging findings on magnetic resonance imaging scans, are essential for the differential and definitive diagnosis, which was nevertheless established only after a histological study of the excised mass by miniarthrotomy.

Resumo Os autores apresentam um caso de um fibroma da bainha de tendão com localização intra-articular no joelho e origem na gordura infrapatelar. Esta localização específica é extremamente rara, sendo este o quarto caso descrito de uma entidade que raramente afeta grandes articulações. Para o seu diagnóstico aspetos clínicos, epidemiológicos e sobretudo achados imagiológicos da ressonância magnética são fundamentais. Neste caso o diagnóstico definitvo foi apenas estabelecido após estudo histológico da massa excisada por mini-artrotomia.

Objective: To investigate the clinicopathological features, immunophenotypes and molecular genetics of fibroma of tendon sheath (FTS). Methods: One hundred and thirty-four cases of FTS or tenosynovial fibroma diagnosed in the Department of Pathology, West China Hospital, Sichuan University, Chengdu, China from January 2008 to April 2019 were selected. The clinical and histologic features of these cases were retrospectively reviewed. Immunohistochemistry, fluorescence in situ hybridization (FISH) and reverse transcription-polymerase chain reaction (RT-PCR) were performed on the above cases. Results: There were a total of 134 cases of FTS, including 67 males and 67 females. The patients' median age was 38 years (ranged from 2 to 85 years). The median tumor size was 1.8 cm (ranged from 0.1 to 6.8 cm). The most common site was the upper extremity (76/134, 57%). Follow-up data was available in 28 cases and there was no detectable recurrence. Classic FTS (114 cases) were well-defined and hypocellular. A few spindle-shaped fibroblasts were scattered in the dense collagenous sclerotic stroma. Characteristically elongated slit-like spaces or thin-walled vessels were observed. Most of cellular FTSs (20 cases) were well-defined and the area with increased cellularity of the spindle cells coexisted with classic FTS. There were occasional mitotic figures, but no atypical mitotic figures. Immunohistochemistry was performed in 8 cases of classic FTS and most cases were positive for SMA (5/8). Immunohistochemistry was also performed in 13 cases of cellular FTS and showed 100% positive rate for SMA. FISH was conducted on 20 cases of cellular FTS and 32 cases of classical FTS. USP6 gene rearrangement was found in 11/20 of cellular FTS. Among 12 cases of CFTS with nodular fasciitis (NF)-like morphological feature, 7 cases showed USP6 gene rearrangement. The rearrangement proportion of USP6 gene in cellular FTS without NF-like morphological features was 4/8. By contrast, 3% (1/32) of the classic FTS showed USP6 gene rearrangement. RT-PCR was performed in those cases with detected USP6 gene rearrangement and sufficient tissue samples for RT-PCR. The MYH9-USP6 fusion gene was detected in 1 case (1/8) of the cellular FTSs, while no target fusion partner was detected in the classic FTS. Conclusions: FTS is a relatively rare benign fibroblastic or myofibroblastic tumor. Our study and recent literature find that some of the classic FTS also show USP6 gene rearrangements, suggesting that classical FTS and cellular FTS are likely to be at different stages of the same disease (spectrum). FISH for USP6 gene rearrangement may be used as an important auxiliary diagnostic tool in distinguishing FTS from other tumors.

@#A 31-year-old Indian female with a history of near-total thyroidectomy 2.5-years prior presented with recurrent neck swelling. Magnetic resonance imaging (MRI) of the neck revealed an infiltrating mass involving the thyroid bed. Biopsy from the mass and review of slides from the previous thyroidectomy revealed a spindle cell tumour with interspersed areas of fibrosis and infiltrative edges entrapping thyroid follicles. Beta-catenin immunopositivity and CTNNB1 mutation confirmed the diagnosis of fibromatosis. The case is being reported for its rarity and the discussion of its differential diagnoses.

Introdução: A síndrome de Meigs é uma condição clínica rara, definida como a associação de derrame pleural, ascite e fibroma ovariano, com resolução dos sintomas após a ressecção do tumor. Relato do caso: Paciente, sexo feminino, 56 anos, com tosse seca, associada à hiporexia, à perda de peso e à dispneia progressiva durante um mês. Radiografia de tórax e posteriormente tomografia de tórax mostraram derrame pleural volumoso à direita, sendo realizada toracocentese com drenagem de 2.500 ml de líquido seroso, sugestivo de exsudato. Ao exame, observou-se massa palpável em hipogástrio, com limite superior em cicatriz umbilical. Exames de imagem mostram formação expansiva sólida de possível origem ovariana esquerda e presença de líquido ascítico. A paciente foi submetida à histerectomia total com salpingo-ooforectomia bilateral e ressecção da massa pélvica. No intraoperatório, o exame por congelação foi sugestivo de fibroma ovariano. O histopatológico da peça cirúrgica confirmou fibroma ovariano medindo 13,0 x 12,5 x 7,5 cm e o exame citopatológico do líquido ascítico foi negativo para células neoplásicas. A paciente evoluiu em bom estado geral com resolução do derrame pleural e da ascite e segue sem recorrência dos sintomas. Conclusão: O diagnóstico definitivo é feito pela confirmação histológica de fibroma ovariano e resolução dos sintomas após a remoção da tumoração. A dispneia pode ser o sintoma inicial e o marcador tumoral CA-125 pode estar elevado. O prognóstico costuma ser bom e as chances de recidiva são mínimas.

ntroduction: Meigs syndrome is a rare clinical condition, defined as the association of pleural effusion, ascites and ovarian fibroma, with resolution of symptoms after tumor resection. Case report: Female patient, 56 years old, with dry cough associated with hyporexia, weight loss and progressive dyspnea for one month. Chest X-ray and later chest tomography showed massive pleural effusion on the right. Thoracocentesis was performed with drainage of 2,500 ml of serous fluid, suggestive of exudate. On examination, a palpable mass was observed in the hypogastrium, with an upper limit in the umbilicus. Imaging exams show solid expansive formation of possible left ovarian origin and presence of ascitic fluid. The patient underwent total hysterectomy with bilateral salpingo-oophorectomy and resection of the pelvic mass. Intraoperatively, frozen section was suggestive of ovarian fibroma. Histopathological of the surgical specimen confirmed ovarian fibroma measuring 13.0 x 12.5 x 7.5 cm and cytopathological examination of the ascitic fluid was negative for neoplastic cells. The patient evolved in good general condition with resolution of the pleural effusion and ascites and continues without recurrence of symptoms. Conclusion: The definitive diagnosis is made by histological confirmation of ovarian fibroma and resolution of symptoms after removal of the tumor. Dyspnea may be the initial symptom and the CA-125 may be elevated. The prognosis is usually good and the chances of recurrence are minimal.

Tumores cardíacos (TC) em crianças são lesões muito raras, mas seu diagnóstico é fundamental para a conduta adotada para o paciente. A ecocardiografia é a modalidade de imagem cardiovascular mais utilizada na prática clínica para o diagnóstico inicial de TC em pacientes pediátricos. Conhecer as características ecocardiográficas das TCs pode possibilitar um diagnóstico cada vez mais precoce e a identificação de sua etiologia mais provável. Os TCs primários e benignos são os mais frequentes na população pediátrica. Entre os TCs benignos, os mais frequentes em fetos e neonatos são rabdomiomas e teratomas. Em crianças e adolescentes, rabdomiomas e fibromas são os mais comuns. Neste artigo, descrevemos as características ecocardiográficas dos principais TCs em idades pediátricas.(AU)

Cardiac tumors (CTs) in children are very rare, but their diagnosis is crucial for patient management. Echocardiography is the most commonly used cardiovascular imaging modality in clinical practice for the initial diagnosis of CTs in pediatric patients. Knowing the echocardiographic characteristics of CTs can enable an increasingly early diagnosis and the identification of its most likely etiology. Primary and benign CTs are the most frequent types in the pediatric population. Among benign CTs, the most frequent in fetuses and neonates are rhabdomyomas and teratomas. In children and adolescents, rhabdomyomas and fibromas are more common. Here we describe the echocardiographic characteristics of the most common CTs in pediatric patients.(AU)

El mixoma odontogénico es una neoplasia de origen mesenquimal, con crecimiento lento pero localmente invasivo y agresivo, que cuenta con un aspecto histológico característico. Radiográficamente, la mayoría de las lesiones tienen un aspecto radiolúcido multilocular, descrito en la literatura como «panal de abejas¼ o «burbujas de jabón¼, que ocasionan desplazamiento dental y expansión corticales. En el ámbito histopatológico, se caracteriza por células estelares o fusiformes con prolongaciones citoplasmáticas, en una sustancia mucoide o mixoide con presencia o no de colágena, cuando contiene grandes cantidades de tejido fibroso celular maduro se le llama mixofibroma. Se presenta un caso clínico de hombre de 38 años, que acude al Hospital General de Uruapan, Michoacán con aumento de volumen en región maxilar derecha; se toma biopsia incisional y se emite el diagnóstico histopatológico de mixofibroma odontogénico, 33.6% de los casos se presenta en el maxilar, con una distribución uniforme por todas las áreas llegando a erosionar el seno maxilar. Tiene una tasa de recurrencia de 10 a 33%, y el tratamiento ideal es la resección en bloque con márgenes de seguridad (AU)

Odontogenic myxoma is a slow-growing locally invasive intraosseous lesion with defined microscopic appearance. Radiographic appearance, is described as multilocular radiolucent lesion, which is reported in scientific literature as «honeycomb¼ or «soap bubbles¼ appearance most of the time; it exhibits dental displacement and cortical expansion. Histopathologically, stellate and spindle cells with cytoplasmic processes are observed in a mucoid or myxoid substance, with or without collagen; when it contains large amounts of mature cellular fibrous tissue, it is called myxofibroma. The present article presents the case of a 38 year old male, who attended the General Hospital in Uruapan, Michoacán due to an increased volume in the right maxillary region. Incisional biopsy was performed and the histopathological diagnosis of odontogenic myxofibroma was emitted. 33.6% of cases occur in the maxilla with a uniform distribution throughout the areas, and can erode the maxillary sinus. It has a recurrence rate of 10 to 33%, therefore ideal treatment is bloc resection leaving safety margins (AU)

El fibroma de fibroblastos gigantes (FFG), conocido también como fibroma de células gigantes, es una pápula o nódulo asintomático localizado en la encía, paladar y lengua, es del mismo color que la mucosa adyacente, de base sésil o pediculada, con superficie lisa o papilar que por lo general mide menos de 1 cm. Objetivo: Identificar las características demográficas e histopatológicas de los casos de FFG de un laboratorio privado de patología bucal en la Ciudad de México. Material y métodos: Se obtuvieron los datos de edad, sexo, diagnóstico presuntivo y definitivo de 122 casos de FFG de 2004 a 2019 con un total de 7,681 muestras. Se describe su distribución por edad, sexo y localización. Resultados: El rango de edad obtenido es de 1 a 84 años, con un promedio de X = 38 años, se presenta con mayor frecuencia en la segunda década de vida, con una razón de 1.6:1 mujer a hombre. La localización más frecuente es en lengua (46%); sin embargo, sólo 49.1% de los estudios especificaban este dato. Conclusión: La importancia de esta lesión es que clínicamente se parece a otras patologías de tejido fibroso, por lo tanto, se debe tener presente al FFG como diagnóstico diferencial (AU)

Giant cell fibroma (GCF) is an asymptomatic papule or nodule that is similar in color to the surrounding mucosa, with a sessile or pedunculated base. It is usually less than 1 cm in size and it features a smooth or papillary surface. Objective: To identify the demographic and histopathological characteristics of GCF cases in a private oral pathology laboratory in Mexico City. Material and methods: Data on age, sex, as well as on presumptive and definitive diagnosis of 122 GCF cases were obtained from 2004 to 2019 with a total of 7,681 samples. Its distribution by age, sex and localization is described. Results: The age range obtained is from 1 to 84 years, with a mean age of 38 years. Frequently during the second decade of life, the female to male ratio is 1.6:1. The most frequent location is the tongue (46%), however, only 60 of 122 studies specified this data. Conclusion: Since this lesion clinically resembles another fibrous tissue pathology, it is warranted to have prior knowledge on its clinical characteristics, as GCF should be regarded as a differential diagnosis (AU)

Meigs' syndrome (MS), a rare complication of benign ovarian tumors, is easily misdiagnosed as ovarian cancer (OC). We retrospectively reviewed the clinical laboratory data of patients diagnosed with MS from 2009 to 2018. Serum carbohydrate antigen 125 and HE4 levels were higher in the MS group than in the ovarian thecoma-fibroma (OTF) and healthy control groups (all P < 0.05). However, the serum HE4 levels were lower in the MS group than in the OC group (P < 0.001). A routine blood test showed that the absolute counts and percentages of lymphocytes were significantly lower in the MS group than in the OTF and control groups (all P < 0.05). However, these variables were higher in the MS group than in the OC group (both P < 0.05). The neutrophil-to-lymphocyte ratio (NLR) was also significantly lower, whereas the lymphocyte-to-monocyte ratio was higher in the MS group than in the OC group (both P < 0.05). The NLR, platelet-to-lymphocyte ratio, and systemic immune index were significantly higher in the MS group than in the OTF and control groups (all P < 0.05). The hypoxia-inducible factor-1 mRNA levels were also significantly higher, whereas the glucose transporter 1, lactate dehydrogenase, and enolase 1 mRNA levels were lower in peripheral CD4

BACKGROUND: Spontaneous disease stabilization of desmoid-type fibromatosis (DF) has been demonstrated in many reports, and the watchful waiting approach without any frontline treatment is becoming popular as an initial management strategy. In this study, we aimed to assess the disease stabilization rate and identify predictive factors for disease stabilization of DF in patients with conservative treatment.METHODS: We reviewed 76 patients with sporadic extra-abdominal DF who were managed with frontline conservative treatment in our institute. The minimum follow-up was 12 months. Stabilization was defined as radiological evidence of no change or continuous decrease in size of the tumor for six months or more. The primary endpoint was stabilization of DF. Possible patient-, disease-, and treatment-related factors predictive of disease stabilization were analyzed with multivariate analysis.RESULTS: At final follow-up, 54 of the 76 tumors (71%) were stable, and mean time to stabilization was 30.4 months (range, 7 to 112 months). On Kaplan-Meier survival analysis, the spontaneous stabilization rate was 25.4% at one year, 52.7% at two years, and 70.9% at three years. The mean time to spontaneous stabilization was longer in patients with ≤ 40 years of age (p = 0.022) or recurrence (p = 0.041). On multivariate analysis with the Cox proportional hazard method, recurrence (hazard ratio [HR], 1.79; p = 0.041) and younger age (HR, 2.04; p = 0.022) were identified as independent prognostic factors for longer time to disease stabilization.CONCLUSIONS: Frontline conservative treatment seems to be the optimal treatment for most patients with DF. Younger patients or those with recurrence may require longer time to spontaneous disease stabilization.

Solitary fibrous tumor (SFT) is a relatively uncommon mesenchymal neoplasm that usually arises in the pleura, but also has been reported in numerous extrapleural locations, including cutaneous site. The skin lesion presents as a circumscribed nodule or tumor, mainly on the head and neck. A 41-year-old male presented with 6 months history of nail lesion without symptom on the left third finger. The lesion is slightly yellowish discoloration with subungual erythematous nodule and distal onycholysis. Biopsy specimen from the nail lesion showed the spindle cells form patternless pattern with hypercellular and hypocellular area. And small blood vessels and dilated vascular spaces were present. The result of special stain for specimen showed that positive for CD34, Bcl-2, and CD99 but negative for S-100, FactorXIIIa, and smooth muscle action. Recognition of this uncommon location of SFT is important because of possible confusion with other subungual tumors, including glomus tumor, fibroma and other fibrohistiocytic tumors like dermatofibrosarcoma protuberans, superficial acral fibromyxoma and cellular digital fibroma. Here in, we report a case of SFT of subungual region. We think this case is interesting because of uncommon location and may be helpful to more understand the character of this disease.

RESUMEN: El fibroma odontogénico central (FOC) es una neoplasia benigna poco frecuente que representa alrededor del 1.5% de los tumores odontogénicos intraóseos. Su presentación es exclusiva de huesos maxilares. Tiene origen mesodérmico, pudiendo derivar del folículo dentario, ligamento periodontal y/o la papila dental. Tradicionalmente presenta dos variantes histológicas: un tipo que es pobre en epitelio y otro tipo que es rico en epitelio con focos de material calcificado. En la mayoría de los casos muestra un crecimiento lento y progresivo que produce expansión cortical con o sin sintomatología. Radiográficamente es común observar una imagen radiolúcida y unilocular, raramente se pueden exhibir lesiones multiloculares y/o de radiolucidez mixta. El tratamiento indicado en la mayoría de los casos es la enucleación del tumor. El siguiente reporte de caso describe las características clínicas, imageneológicas e histopatológicas de una lesión mandibular con diagnóstico de FOC y cuyo tratamiento realizado fue la enucleación del tumor.

ABSTRACT: Central odontogenic fibroma (COF) is a rare benign neoplasm that accounts for about 1.5% of intraosseous odontogenic tumors. Its presentation is exclusively in the maxillary bones. It has a mesodermal origin, being able to derive from the dental follicle, periodontal ligament and/or the dental papilla. Traditionally, it has two histological variants: one type that is poor in epithelium and another type that is rich in epithelium with foci of calcified material. In most cases it shows a slow and progressive growth that produces cortical expansion with or without symptomatology. Radiographically, it is common to observe a radiolucent and unilocular image, but rarely multilocular lesions and / or mixed radiolucency can be exhibited. The treatment indicated in most cases is the enucleation of the tumor. The following case report describes the clinical, imaging and histopathological characteristics of a mandibular lesion diagnosed with FOC and whose treatment was enucleation of the tumor.
