Fibroma mole gigante vulvar: relato de caso / Giant soft vulvar fibroma: case report

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.

Fibromatosis mamaria. Reporte de dos casos clínicos y revisión bibliogáfica / Mammary fibromatosis. Two case report and review of literatura

RESUMEN Introducción y objetivos: La fibromatosis produce tumores benignos pero localmente agresivos, que afectan a los tejidos blandos. A nivel mamario, representa tan sólo el 0.2% de las neoplasias de la mama. Nuestro objetivo con el presente artículo es profundizar en el conocimiento de la fibromatosis mamaria, a través del estudio de dos casos clínicos, mostrando sus características clínico-radiológicas e histológicas, e intentar establecer un protocolo de actuación adecuado. Métodos: Estudio retrospectivo de dos casos clínicos de fibromatosis mamaria diagnosticados en el Hospital Universitario La Paz entre los años 2018 y 2019. Resultados: Presentaremos dos pacientes con diagnóstico de fibromatosis mamaria, ambas debutaron con la autopalpación de un nódulo mamario. Al realizarles una ecografía, se visualizó un nódulo sólido, mal definido y axila ecográficamente negativa, que precisó de biopsia-aspiración con aguja gruesa. En los dos casos, se decidió resección quirúrgica de la lesión. Seguimiento mediante exploración mamaria y pruebas de imagen periódicas. Conclusiones: Aunque se trata de una entidad benigna, la fibromatosis mamaria puede simular un proceso maligno, tanto clínica como radiológicamente, por lo que precisa de un estudio histológico. A pesar de que la diseminación metastásica es muy poco frecuente, no se debe olvidar el carácter agresivo a nivel local de esta patología, y sus altas tasas de recurrencia. Como tratamiento, se debe realizar una resección quirúrgica, aunque recientemente se ha contemplado la opción de vigilancia estrecha sin tratamiento. No existe evidencia científica que justifique la utilización de otros tratamientos como la radioterapia o el tratamiento hormonal.

ABSTRACT Introduction and objectives: Fibromatosis produces benign but locally aggressive tumours that affect soft tissues. At breast level, it represents only 0.2% of breast neoplasms. Our goal with this article is to increase knowledge on breast fibromatosis, through the study of two clinical cases; explaining their clinical-radiologic and histological characteristics. Additionally, try to establish an adequate protocol, for the management of the disease and for its subsequent monitoring. Methods: A retrospective study about two clinical cases of breast fibromatosis diagnosed in La Paz Hospital between 2018-2019. Results: both patients presented with clinical manifestations, autopalpation of a breast nodule. A breast ultrasound was performed and a solid nodule was visualized, with poorly defined edges and ecographically negative armpit. A core needle biopsy was performed to confirm the histological diagnosis. In both clinical cases, the treatment was surgical resection of the lesion. Periodic revisions are being performed in order to exclude recurrence. Conclusions: Although it is a benign disease, breast fibromatosis can simulate a malignancy, both in a clinical and radiological way, so histological study is mandatory in order to achieve an accurate diagnosis. Even metastatic dissemination is extremely rare, the local aggressive nature and high rates of recurrence for fibromatosis makes surgical excision, with wide free margins, the most important tool in treatment, although the possibility of close surveillance without treatment is recently being contemplated. There is no scientific evidence to justify the use of other treatments such as radiotherapy or hormonal treatment.

Conservative treatment of odontogenic fibromixoma in maxilla with 11-year follow-up: case report

Introduction: Odontogenic mixomas (OMs) are a locally infiltrating slow-growing intraosseous nonmetastasizing tumors of the maxilla and the mandible that have the potential for bone des-truction and cortical expansion, showing high recurrence rates. Their frequency varies around the world, accounting for 3-20% of all odontogenic tumors, ranking third among odontogenic tumors. They predominantly affect young adults, but may occur in various age groups. Report: A 37-year-old female patient who in August 2005 sought treatment at the Maxillofacial Dental Unit at Hospital Higueras, Talcahuano, Chile, for a left maxillary bone lesion. An increase in vo-lume was observed in the left maxillary region in the clinical analysis of the oral cavity. The neo-plasm was sessile and painless, measuring approximately 3 cm, with a greater diameter in the vestibule, firm on palpation and without signs of gangliopathy. Computed cone beam tomogra-phy imaging showed an extensive infiltrating osteolytic lesion in the left maxillary sinus, with noinvolvement of the orbital bone structure. Analysis of incisional biopsy yielded the diagnosis ofOdontogenic Fibromixoma. It was proposed to perform the conservative treatment of the lesion,consisting of enucleation and surgical curettage, obtaining excellent postoperative results and absence of relapse after 11-year follow-up. Conclusion: The present case report provides eviden-ce that supports the conservative surgical approach for the treatment of odontogenic myxomas, which contributes to a better postoperative quality of life for the patient.

Tumor desmoides cervical: reporte de caso / Cervical desmoid tumor: case report

El tumor desmoides es un tumor benigno raro, de origen fibroblastico no inflamatorio, algunas veces referido como fibromatosis no agresiva. Su etiología aún no está completamente clara, sin embargo, se asocia habitualmente a trauma previo y/o procedimientos quirúrgicos. La ubicación más frecuente es abdominal, el cual posee características imagenologicas claras, al igual que su presentación musculo esquelética plantar. La presentación fuera de estos lugares es infrecuente y difícil de diagnosticar. Presentamos un caso de un tumor desmoides cervical que genero un gran desafío diagnóstico, identificando sus claves diagnósticas y realizando una revisión de la bibliografía al respecto para esta ubicación.

Desmoid tumours are a rare benign tumour of fibroblastic non inflammatory origin, sometimes referred as non aggressive fibromatosis.The etiology is not yet completely clear, however, it is usually associated with previous trauma and / or surgical procedures. The most frequent location is in the abdomen, which has typical images characteristics, as well as its skeletal muscle presentation at the plantar level. The presentation outside these places is infrequent and difficult to diagnose. We present a case of a cervical desmoid tumour that generated a great diagnostic challenge, identifying its key imaging characteristics and performing a literature review of the bibliography regarding this location.

Remoção cirúrgica de fibroma traumático: relato de caso clínico / Surgical removal of the traumatic fibroid: clinical case report

O objetivo deste estudo é descrever o diagnóstico e conduta clínica no tratamento do Fibroma Traumático (FT). O FT é uma lesão proliferativa de natureza benigna que surge na cavidade bucal devido à traumas de repetição, que desencadeiam reações inflamatórias em tecido conjuntivo, causando uma hiperplasia tecidual, geralmente assintomática, podendo interferir na mastigação e na fala causando desconforto ao paciente. Sua prevalência é alta, geralmente em mucosa jugal, linha oclusal, mucosa labial, língua e gengiva. O tratamento consiste na excisão cirúrgica e a confirmação do diagnóstico é dado através de envio para exame histopatológico. Paciente do gênero masculino, 46 anos de idade, procurou atendimento por apresentar nódulo único, exofítico, unilateral de aproximadamente 3 cm em seu diâmetro, localizado na mucosa jugal do lado direito, com bordas regulares e indolor a palpação, apresentando há cerca de 12 meses. Foi submetido a remoção cirúrgica total da lesão e encaminhamento ao laboratório para análise histopatológica para confirmação diagnóstica, além de proservação do caso em 7, 30 e 60 dias. Desta forma, foi possível concluir que a excisão cirúrgica da lesão promove maior conforto, melhora na fala e mastigação, além de um bom reparo tecidual, devolvendo assim, condições de saúde a mucosa bucal e mínimas chances de recidiva(AU)

The objective of this study is to describe the diagnosis and clinical management in the treatment of Traumatic Fibroma (FT). FT is a proliferative lesion of benign nature that arises in the buccal cavity due to repetitive traumas, which trigger inflammatory reactions in connective tissue, causing a tissue hyperplasia, usually asymptomatic, that can interfere in chewing and speech causing discomfort to the patient. Its prevalence is high, usually in jugal mucosa, occlusal line, labial mucosa, tongue and gingiva. The treatment consists of surgical excision and confirmation of the diagnosis is given by sending for histopathological examination. A 46-year-old male patient sought care for having a single, exophytic, unilateral nodule of approximately 3 cm in diameter, located on the right side of the jugal mucosa, with regular borders and painless palpation, presenting about 12 months. He was submitted to total surgical removal of the lesion and sent to the laboratory for histopathological analysis for diagnostic confirmation, in addition to case proservation at 7, 30 and 60 days. In this way, it was possible to conclude that the surgical excision of the lesion promotes greater comfort, improvement in speech and chewing, besides a good tissue repair, thus returning health conditions to the oral mucosa and minimal chances of relapse(AU)

Accidente cerebrovascular embólico secundario a fibroelastoma papilar de válvula mitral / Embolic stroke secondary to a mitral valve fibroelastoma: case report

Embolic stroke secondary to cardiac tumors is uncommon. However, 25-30% of cardiac tumors may cause systemic emboli. We report a 29-year-old male consulting for a sudden episode of aphasia and right hemiparesis, compatible with infarct of the left middle cerebral artery territory. Transthoracic echocardiography reported an ovoid tumor of 8 × 7 × 7 mm in relation to the sub valvular apparatus of the mitral valve. After neurologic stabilization, surgical treatment was performed. Approached by median sternotomy and in cardiopulmonary bypass, the mitral valve was explored. A macroscopic tumor consistent with a papillary fibroelastoma curled in sub valvular chordae was found. It was deployed and resected from its base, while the anterior mitral leaflet was preserved intact. Histopathological examination confirmed the intraoperative macroscopic diagnosis. The patient recovered uneventfully postoperatively and was discharged on the fifth day after surgery. He currently is in functional capacity I without cardiovascular symptoms at five years follow-up.

Outcomes after surgical resection of primary non-myxoma cardiac tumors

Abstract Objective: Primary cardiac tumors are rare lesions with different histological type. We reviewed our 17 years of experience in the surgical treatment and clinical results of primary non-myxoma cardiac tumors. Methods: Between July 2000 and February 2017, 21 patients with primary cardiac tumor were surgically treated in our institution. The tumors were categorized as benign non-myxomas and malignants. Data including the demographic characteristics, details of the tumor histology and grading, cardiac medical and surgical history, surgical procedure of the patients were obtained from the hospital database. Results: Eleven patients were diagnosed with benign non-myxoma tumor (male/female:7/4), ranging in age from 10 days to 74 years (mean age 30.9±26.5 years). Papillary fibroelastoma was the most frequent type (63.6%). There were two early deaths in benign group (all were rhabdomyoma), and mortality rate was 18%. The mean follow-up period was 69.3±58.7 months (range, 3 to 178 months). All survivals in benign group were free of tumor-related symptoms and tumor relapses. Ten patients were diagnosed with malignant tumor (sarcoma/lymphoma:8/2, male/female:3/7), ranging in age from 14 years to 73 years (mean age 44.7±18.9 years). Total resection could be done in only three (30%) patients. The mean follow-up period was 18.7±24.8 months (range, 0-78 months). Six patients died in the first 10 months. Conclusion: Complete resection of the cardiac tumors, whenever possible, is the main goal of surgery. Surgical resection of benign cardiac tumors is safe, usually curative and provides excellent long-term prognosis. On the contrary, malignant cardiac tumors still remain highly lethal.

Fibroelastoma papilar cardíaco: estudio retrospectivo: Presentación clínica y resultados quirúrgicos / Fibroelastoma papilar cardíaco: estudio retrospectivo: Presentación clínica y resultados quirúrgicos

Los fibroelastomas papilares cardíacos son pequeños tumores benignos con potencial embolígeno. Con la incorporación de la ecocardiografía y la mejoría en la resolución de las imágenes, el diagnóstico clínico es cada vez más frecuente, y en series recientes su frecuencia supera a la del mixoma cardíaco. Nuestro objetivo fue analizar las características de una serie de casos de fibroelastoma papilar cardíaco con confirmación histológica operados en nuestro hospital. Analizamos retrospectivamente los tumores cardíacos y las características clínicas de los pacientes operados desde junio de 1992 a febrero de 2017. De 108 operados, 18 presentaron fibroelastoma papilar. La edad media del grupo con fibroelastoma papilar fue 58 años (22-77); 10 eran varones. Las localizaciones más frecuentes fueron la válvula aórtica (7) y la válvula mitral (5). Ninguno presentó disfunción valvular significativa. Por ecografía transesofágica, el tamaño (diámetro mayor) fue 13.33 ± 5.55 mm (6.6-28.0). Cuatro pacientes eran sintomáticos; uno presentaba disnea, otro aleteo auricular, dos con fibroelastoma en válvula aórtica habían sufrido un accidente cerebrovascular. Los restantes, asintomáticos, fueron intervenidos preventivamente. En 15 pacientes el tumor se extirpó sin necesidad de reemplazo valvular. No hubo mortalidad quirúrgica ni recidiva tumoral en el seguimiento de 2.6 años. Se concluye que los fibroelastomas papilares cardíacos pueden ser extirpados con buenos resultados a mediano plazo y, en su mayoría, con preservación valvular. Sin embargo, no existen aún estudios aleatorizados que avalen la escisión quirúrgica en pacientes asintomáticos. Por el momento, esta última depende de la experiencia del grupo quirúrgico tratante.

Papillary ibroelastomas are small benign intracardiac tumors known for their embolic potential. Since the introduction of echocardiography with improved resolution and transesophageal imaging techniques, they are being increasingly detected in clinical practice. In recent series, papillary fibroelastoma is considered the most frequent benign tumor of the heart. Our objective was to analyze characteristics and midterm surgical outcome of histologically-confirmed cases of papillary fibroelastoma. We conducted a retrospective study on patients with cardiac tumors submitted to surgical excision between June 1992 and February 2017. Out of 108 patients, 18 had papillary fibroelastomas. Their mean age was 58 years (22-77); 10 were men. The most frequent localizations were the aortic valve (7) and the mitral valve (5). None had significant valvular dysfunction. By transesophageal echocardiography, the tumor size (larger diameter) was 13.33 ± 5.55 mm (6.6-28.0). Two patients, both with tumor in the aortic valve, had suffered a stroke; other two had dyspnoea and atrial flutter, respectively. The remaining 14 patients were asymptomatic and their tumors were incidental findings. In 15 patients the valve was preserved. There was neither surgical mortality nor recurrence after 2.6 years of follow-up. In conclusion, most papillary fibroelastomas can be surgically removed with valve preservation and favorable clinical outcome. However, until the results of randomized trials support the decision, an aggressive surgical approach in asymptomatic patients needs to be defined in the context of surgical expertise.

Fibromatose agressiva (tumor desmoide) associada ao implante mamário: revisão da literatura e apresentação de três novos casos / Aggressive fibromatosis (desmoid tumor) associated with breast implant: literature review and presentation of three new cases

INTRODUÇÃO: As fibromatoses consistem na proliferação de tecido fibroso, na forma de faixas ou nódulos, associadas às fáscias e aponeuroses. Sua variedade agressiva, denominada previamente tumor desmoide, se comporta de forma semelhante a uma neoplasia maligna, com destruição local de tecidos, sem, entretanto, originar metástases. MÉTODOS: Fez-se revisão da literatura de1979 a janeiro de 2017. Dados de três pacientes, operados entre maio de 2010 e agosto de 2015, foram revistos, com proservação até março de 2017. Observaram-se idade, características do implante, via de introdução do mesmo, tempo decorrido entre o implante e o aparecimento da fibromatose, tratamento cirúrgico instituído, acompanhamento clínico e resultados. RESULTADOS: Foram encontrados 24 trabalhos na literatura disponível, versando sobre fibromatose agressiva da parede torácica associada ao implante mamário de silicone, nos quais foram relatados 34 casos. São apresentados três casos de fibromatose agressiva associados ao implante mamário de silicone. Os casos foram tratados com sucesso por ressecção alargada da parede torácica, incluindo pele, musculatura, costelas, fáscia endotorácica e pleura parietal. A reconstrução foi bem-sucedida, realizada com tela aloplástica (Prolene & reg;) recoberta por retalho muscular em dois casos e retalho cutâneo local em um caso. CONCLUSÃO: A associação de fibromatose agressiva e implante mamário é rara. O tratamento deve consistir em cirurgia alargada, removendo-se o implante e toda a área da cápsula adjacente, em conjunto com parte da mama, costelas subjacentes, musculatura intercostal, fáscia endotorácica e pleura parietal. A reconstrução deve ser feita com tela aloplástica associada a retalho muscular ou retalho tegumentar local.

INTRODUCTION: Fibromatoses consists of the proliferation of fibrous tissue, in the form of bands or nodules, associated with fasciae and aponeuroses. The aggressive variety, previously denominated desmoid tumor, behaves similarly to malignant neoplasm, with local destruction of tissues, without, however, producing metastases. METHODS: A literature review was carried out from 1979 to January 2017. Data from three patients, operated between May 2010 and August 2015, were reviewed. Age, implant characteristics, route of introduction, time elapsed between implantation and fibromatosis, surgical treatment, clinical follow-up and results were observed. RESULTS: Twenty-four papers were found in the literature reporting aggressive fibromatosis of the chest wall associated with silicone breast implant. In these studies, 34 cases were reported. Three new cases of aggressive fibromatosis associated with silicone breast implant are now presented. These cases were successfully treated by extensive resection of the chest wall, including skin, musculature, ribs, endothoracic fascia, and parietal pleura. The reconstruction was successful, performed with alloplastic mesh (Prolene & reg;) covered by muscular flap in two cases and local skin flap in one case. CONCLUSION: The association of aggressive fibromatosis and breast implant is rare. The treatment should consist of extensive surgery, removing the breast implant and the entire area of the capsule around it, part of breast, together with the underlying ribs, intercostal muscles, endothoracic fascia and parietal pleura. The reconstruction should be made with an alloplastic mesh, covered by muscular flaps or local skin flap.

Storiform collagenoma: case report / Colagenoma estoriforme: relato de caso

Storiform collagenoma is a rare tumor, which originates from the proliferation of fibroblasts that show increased production of type-I collagen. It is usually found in the face, neck and extremities, but it can also appear in the trunk, scalp and, less frequently, in the oral mucosa and the nail bed. It affects both sexes, with a slight female predominance. It may be solitary or multiple, the latter being an important marker for Cowden syndrome. It presents as a painless, solid nodular tumor that is slow-growing. It must be considered in the differential diagnosis of other well-circumscribed skin lesions, such as dermatofibroma, pleomorphic fibroma, sclerotic lipoma, fibrolipoma, giant cell collagenoma, benign fibrous histiocytoma, intradermal Spitz nevus and giant cell angiohistiocytoma.

O colagenoma estoriforme é um tumor raro originado a partir da proliferação de fibroblastos com produção aumentada de colágeno tipo I. É encontrado mais frequentemente na face, pescoço e extremidades, podendo aparecer no tronco, couro cabeludo e, raramente, na mucosa oral e leito subungueal. Afeta ambos os gêneros, com discreta predominância em mulheres. Pode ser solitário ou múltiplo, sendo que, neste caso, é um importante indicador da presença de síndrome de Cowden. Apresenta-se como tumor sólido, nodular, de crescimento lento e indolor. Deve constar como diagnóstico diferencial de tumores cutâneos bem delimitados, como dermatofibroma, fibroma pleomórfico, lipoma esclerótico, fibrolipoma, colagenoma de células gigantes, histiocitoma fibroso benigno, nevo de Spitz intradérmico e angioistiocitoma de células gigantes.

Fibro-epithelial Polyp - Report of Two Cases with Literature Review.

Irritation fibroma or traumatic fibroma is a common sub-mucosal response to trauma from teeth or dental prosthesis presenting as a painless, sessile or occasionally pedunculated swelling that can be firm and resilient or soft and spongy in consistency. It rarely occurs before the fourth decade and shows no preference for either sex. Its occurrence corresponds with intraoral areas that are prone to trauma such as the tongue, buccal mucosa and labial mucosa. As the lesion occurs due to continuous trauma and irritation, it important to remove the source of the irritation and then treat it by conservative surgical excision otherwise it will recur.

Fibroma osificante juvenil, presentación de un caso clínico y revisión de la literatura / Juvenil ossifying fibroma, case report and review of the literature

Se presenta el caso de una paciente de seis años, de sexo femenino sin antecedentes mórbidos ni familiares de importancia, quien consulta por proptosis izquierda en abril de 2011. Se realiza resonancia magnética de cerebro evidenciándose un tumor de seno etmoidal con compromiso de órbita izquierda que ocasiona exoftalmo. La biopsia endoscópica nasal fue compatible con fibroma osificante juvenil. Posteriormente se realiza antrostomía con etmoidectomía en dos tiempos, con resultados satisfactorios para la paciente. Aunque el fibroma osificante juvenil es un tipo de lesión benigna poco frecuente, puede llegar a ser muy agresiva y con una alta tasa de recidiva en ciertas ocasiones, por lo que se debe tener en cuenta para realizar un diagnóstico y tratamiento precoz, con un seguimiento programado a largo plazo.

This paper presents the case of a patient of six years old female without background or important morbidly in her family, who consults for left-sided proptosis in April of 2011. It performs brain magnetic resonancebeing demonstrated a tumor of theethmoid sinus with commitment to the left orbit that causes exophthalmus. Nasal endoscopic biopsy was compatible with juvenile ossifying fibroma. It was subsequently performed ananthrostomy whitethmoidectomy in two times, with satisfactory results for the patient. Although the Juvenile ossifying fibroma is a rare type of benign lesion, can be very aggressive and have a high recurrence rate in certain occasions, by what should be taken into account to make an early diagnosis and treatment, with a scheduled follow up in the long term.

Superficial Acral Fibromyxoma involving the nail's apparatus. Case report and literature review

Superficial Acral Fibromyxoma is a rare tumor of soft tissues. It is a relatively new entity described in 2001 by Fetsch et al. It probably represents a fibrohistiocytic tumor with less than 170 described cases. We bring a new case of SAF on the 5th toe of the right foot, in a 43-year-old woman. After surgical excision with safety margins which included the nail apparatus, it has not recurred (22 months of follow up). We carried out a review of the location of all SAF published up to the present day.

Mucocele and Fibroma: Treatment and Clinical Features for Differential Diagnosis

Mucocele is a benign lesion occurring in the buccal mucosa as a result of the rupture of a salivary gland duct and consequent outpouring of mucin into soft tissue. It is usually caused by a local trauma, although in many cases the etiology is uncertain. Mucocele is more commonly found in children and young adults, and the most frequent site is the lower inner portion of the lips. Fibroma, on the other hand, is a benign tumor of fibrous connective tissue that can be considered a reactionary connective tissue hyperplasia in response to trauma and irritation. They usually present hard consistency, are nodular and asymptomatic, with a similar color to the mucosa, sessile base, smooth surface, located in the buccal mucosa along the line of occlusion, tongue and lip mucosa. Conventional treatment for both lesions is conservative surgical excision. Recurrence rate is low for fibroma and high for oral mucoceles. This report presents a series of cases of mucocele and fibroma treated by surgical excision or enucleation and the respective follow-up routine in the dental clinic and discusses the features to be considered in order to distinguish these lesions from each other.

Mucocele é uma lesão comum na mucosa bucal, que resulta da ruptura de um ducto de glândula salivar e consequente derramamento de mucina para o interior dos tecidos moles circunjacentes. Frequentemente este derrame resulta de trauma local, embora em muitos casos a etiologia seja indefinida. É uma lesão não infecciosa benigna, que frequentemente afeta a cavidade bucal de crianças e adultos jovens, localizando-se geralmente na porção interna dos lábios inferiores. Por outro lado, o fibroma é um tipo de tumor benigno do tecido conjuntivo fibroso que pode ser considerado uma hiperplasia reacional do tecido conjuntivo em resposta a traumas e irritação. Geralmente são nodulares, com consistência firme, assintomáticos, coloração semelhante à da mucosa, base séssil, superfície lisa, localizados na mucosa jugal ao longo da linha de oclusão, língua e mucosa labial. O tratamento convencional para ambas as lesões é a excisão cirúrgica conservadora, sendo que sua recorrência é rara para fibromas e alta para as mucoceles. Este trabalho relata casos clínicos de mucocele e fibroma, tratados pela técnica de excisão cirúrgica ou enucleação, bem como descreve a proservação no consultório odontológico. As características importantes para o diagnóstico diferencial dessas lesões são discutidas.

Peripheral fibroma obstructing the eruption pathway.

Reactive hyperplasias comprise a group of fibrous connective tissue lesions that commonly occur in oral mucosa secondary to injury. Peripheral fibroma is also a type of reactive hyperplasia. Peripheral fibroma is a reactive hyperplastic mass that occurs on the gingiva and is derived from connective tissue of the submucosa or periodontal ligament. It may occur at any age, although it does have a predilection for young adults. Females develop these lesions more commonly than do males. Here, we are presenting a case report of a child who is 6 years old and presented to us with a swelling in the lower anterior region which was providing discomfort to the child and also was obstructing the eruption pathway of the permanent central incisor in the region. The lesion was surgically excised.

Fibroelastoma papilífero: relato de sete casos / Papillary fibroelastoma: report of seven cases / Fibroelastoma papilífero: relato de siete casos

O Fibroelastoma Papilífero é um tumor cardíaco benigno, encontrado principalmente nas válvulas. A maioria é assintomática, mas, quando presentes, são inespecíficos ou relacionados a fenômenos embólicos. Em geral, são diagnosticados em exames de imagem de rotina ou em cirurgias valvares e autópsias. Por sua raridade, há controvérsia sobre sua terapêutica. Descrevemos sete casos diagnosticados e tratados em nossa instituição entre 1989 a 2010, o que constitui a maior casuística nacional dessa patologia até o momento.

The papillary fibroelastoma (PFE) is a benign heart tumor, mainly found in the valves. Most tumors are asymptomatic, but when present, they are nonspecific or related to embolic phenomena. They are usually diagnosed at routine imaging studies or valve surgery and autopsies. Its treatment is controversial, due to its rarity. We describe seven PFE cases diagnosed and treated at our institution between 1989 and 2010, which constitutes the largest national case series study of this pathology to date.
