RESUMO

Desmoid-type fibromatosis (DF) is a rare monoclonal, fibroblastic proliferation characterized by an unpredictable and variable clinical course. We present the case of a 56-year-old woman who underwent total thyroidectomy for papillary thyroid carcinoma in 2012 and who developed a cervical mass at the left laterocervical level during follow-up, raising the diagnosis of tumor recurrence. Computed tomography of the neck showed solid formations with heterogeneous contrast uptake in the right lateral region of the neck. At the level of the thoracic operculum, a second 26-mm formation was observed that medially contacted the left lateral wall of the trachea. Lateral lymphadenectomy was performed, which was incomplete. Histology showed findings consistent with desmoid-type fibromatosis. DF are slowly proliferating, non-metastatic tumors with a highly invasive capacity that are usually present in familial adenomatous polyposis (FAP)-Gardner syndrome. Our case had a history of massive colonic polyposis and first-degree relatives of colorectal cancer.

La fibromatosis de tipo desmoide (FD) es una rara proliferación fibroblástica monoclonal caracterizada por un curso clínico impredecible y variable. Presentamos el caso de una mujer de 56 años intervenida de tiroidectomía total por carcinoma papilar de tiroides en 2012 y que durante el seguimiento desarrolla una masa cervical a nivel laterocervical izquierdo, planteando el diagnóstico de recidiva tumoral. La tomografía computarizada de cuello demostró formaciones sólidas con captación heterogénea de contraste en la región lateral derecha del cuello. A nivel del opérculo torácico se observó una segunda formación de 26 mm que contactaba medialmente con la pared lateral izquierda de la tráquea. Se realizó una linfadenectomía lateral, que resultó incompleta. La histología mostró hallazgos compatibles con FD. La FD son tumores de proliferación lenta, no metastásicos y con una capacidad altamente invasiva que suelen estar presentes en la poliposis adenomatosa familiar (PAF)-síndrome de Gardner. Nuestro caso tenía antecedentes de poliposis colónica masiva y familiares de primer grado de cáncer colorrectal.

RESUMO

Introducción. Los tumores desmoides o fibromatosis agresiva corresponden a neoplasias mesenquimales poco frecuentes. Son tumores localmente agresivos que ocurren especialmente en jóvenes, no desarrollan metástasis a distancia, pero se asocian con invasión locorregional y alta tasa de recurrencia después de la resección. Su etiología es desconocida, pero se ha asociado al síndrome de Gardner, trauma, embarazo, estados hiperestrogénicos y puerperio. El objetivo de este artículo fue hacer una revisión sobre el tema a propósito de un caso clínico. Caso clínico. Se presenta el caso de una paciente puérpera con progresivo y rápido aumento del volumen abdominal. Se realizó una tomografía computarizada de abdomen y pelvis que confirmó la presencia de una masa intraperitoneal bien definida. La paciente fue operada con escisión de la masa y confirmación histológica de tumor desmoide a partir de la muestra de patología. Discusión. Los tumores desmoides tienen una incidencia de 2 a 4 casos por millón de habitantes por año, con leve predominio en el sexo femenino y representan menos del 3 % de los tumores de partes blandas. Aunque el tumor se puede ubicar a nivel intraabdominal o en la pared, la ubicación más común es en las extremidades. Conclusiones. La sospecha y detección del tumor desmoide es fundamental, así como su adecuado estudio, para determinar el tratamiento quirúrgico como fue realizado en este caso

Introduction. Desmoid tumors or aggressive fibromatosis correspond to rare mesenchymal neoplasms. They are locally aggressive tumors that occur especially in young people, they do not develop distant metastases, but are associated with locoregional invasion and a high recurrence rate after resection. Its etiology is unknown, but it has been associated with Gardner syndrome, trauma, pregnancy, hyperestrogenic states, and puerperium. The objective of this article was to review the topic based on a clinical case. Clinical case. The case of a puerperal patient with progressive and rapid increase in abdominal volume is presented. An abdominal and pelvic CT scan was performed, which confirmed the presence of a well-defined intraperitoneal mass. The patient underwent surgery with excision of the mass and histological confirmation of a desmoid tumor from the pathology sample. Discussion. Desmoid tumors have an incidence of 2 to 4 cases per million inhabitants per year, with a slight predominance in females, and represent less than 3% of soft tissue tumors. Although the tumor can be located intra-abdominal or in the wall, the most common location is in the extremities. Conclusions. The suspicion and detection of the desmoid tumor is essential, as well as its adequate study to determine the surgical treatment as it was done in this case

RESUMO

OBJECTIVE: To perform a phenotypic characterization of the dento-osseous anomalies in a Brazilian family with Familial Adenomatous Polyposis (FAP) and to investigate the adenomatous polyposis coli (APC) causative variant. DESIGN: The study included a family of 14 individuals (Group A: affected; Group B: non-affected). The frequency of radiographic findings in both groups was evaluated according to the Dental Panoramic Radiograph Score (DPRS) diagnostic method. The accuracy and reproducibility of DPRS were tested. The DNA was isolated from the index patient's saliva and submitted to whole-exome and Sanger sequencing approach. RESULTS: DPRS ≥ 7 was observed in 80 % of Group A but in none of Group B. The most common findings in Group A were dense bone islands (60 %), hazy sclerosis (40 %), osteomas (40 %), and supernumerary tooth (20 %). DPRS has proved to be a reliable method while DPRS ≥ 5 and DPRS ≥ 7 were taken as positive for FAP, and reproducible diagnosis test considering that the evaluators correctly identified the affected patients (Kappa agreement>0.8, p = 0.002). A nonsense heterozygous mutation in the APC gene (c.1370C > G; p.Ser457*) of the index case was detected. CONCLUSION: FAP patients have a higher frequency of dento-osseous anomalies (p = 0.005). Bone abnormalities were more prevalent than dental anomalies (p = 0.001). Thus, FAP patients should be referred for dental examination and genetic counseling to perform early diagnosis of dento-osseous anomalies and evaluate the implications of the molecular findings in each particular family.

RESUMO

Gardner syndrome (GS) is a genetic disease with high penetration characterized by a signal triad of colonic polyposis, multiple osteomas and mesenchymal tumors in the soft tissues and skin. The colonic polyposis is associated to the development of malignant disease. Patients may also present maxillomandibular alterations such as impacted teeth, supernumerary teeth, congenital missing teeth and odontomas. Bone lesions and maxillomandibular alterations usually precedes the gastrointestinal alterations; hence dentists should be aware of GS syndrome main radiographic signals, in order to detect the disease and proper referred the patient to medical treatment and surveillance. Thus, in this report, it is described a case of GS in a male patient, as well as discussed GS features.(AU)

A síndrome de Gardner (GS) é uma doença genética caracterizada pela seguinte tríade: polipose colônica, múltiplos osteomas e tumores mesenquimais em tecidos moles e pele. A polipose colônica está associada ao desenvolvimento de tumores malignos. Os pacientes também podem apresentar alterações maxilomandibulares, como dentes impactados, dentes supranumerários, agenesia congênita e odontomas. Lesões ósseas e alterações maxilomandibulares geralmente precedem as alterações gastrointestinais; portanto, os dentistas devem estar cientes dos principais sinais imaginológicos da GS, a fim de detectar a doença e encaminhar adequadamente o paciente para tratamento. Neste relato de caso é descrito um caso de GS em um paciente do gênero masculino, além de discutir as características da GS.(AU)

RESUMO

Os osteomas geralmente são lesões solitárias, de crescimento lento e assintomáticas. Os locais de ocorrência mais comuns são o corpo da mandíbula e o côndilo, mas quando envolvem esta região podem causar alterações na oclusão do paciente, desvio progressivo e lento de linha média, assim como aumento do volume facial acompanhado de dor e limitação de abertura bucal. Cerca de 90% dos pacientes portadores da Síndrome de Gardner apresentam anormalidades esqueléticas, fazendo os osteomas as lesões mais frequentes e de maior ocorrência em seios paranasais e nos maxilares. O objetivo deste trabalho é relatar o caso clínico de uma paciente do gênero feminino, portadora de Síndrome de Gardner com osteoma localizado em côndilo mandibular esquerdo que, devido aos sintomas relatados pelo paciente, foi submetida à ressecção cirúrgica por meio de acesso intra oral para melhor abordagem da lesão e que evoluiu para a solução da sintomatologia apresentada como queixa principal quando procurou o serviço de Cirurgia e Traumatologia Buco-maxilo-facial.

Osteomas are usually solitary, slow-growing and asymptomatics lesions. The most common sites of occurrence are condyle and jaw body. Osteomas involving condyle can cause changes in patient’s occlusion, progressive and slow deviation of the midline, as well as increased facial volume accompanied by pain and limited mouth opening. An osteoma located in mandible border is typical of the Gardner’s Syndrome. There are many clinical features of this syndrome, which can affect the skin, endocrine system and orofacial area. About 90% of patients with this condition have skeletal abnormalities, making osteomas the most frequent lesions in the paranasal sinuses and jaws. The objective of this work is to report the clinical case of a female patient with Gardner’s Syndrome with osteoma located in the left mandibular condyle, who was submitted to resection of the lesion.

RESUMO

Gardner syndrome is a hereditary disease in which patients develop gastrointestinal polyps, osteomas, desmoid tumors, epidermoid cysts, fibromas, lipomas, and retinal lesions. Dental abnormalities such as supernumerary or impacted teeth, odontomas and dentigerous cysts are also reported. The most serious concern in this syndrome is the extremely high risk of gastrointestinal polyps undergoing malignant transformation. Since the maxillofacial findings usually precede gastrointestinal polyps, the dentist plays a crucial role in the diagnosis of Gardner syndrome, and panoramic radiography is an important tool in the diagnosis of the disease. We report here a case of Gardner syndrome in a patient showing mandibular osteomas and impacted teeth. Also, cases of Gardner syndrome with maxillofacial manifestations reported in the literature were reviewed and compared with ours. According to the findings, osteomas are important manifestations of this syndrome, and regardless of the absence of family history of intestinal polyposis, their occurrence should prompt diagnostic evaluation for this disease.

RESUMO

La poliposis adenomatosa familiar (PAF) se basa en una mutación autosómica dominante de pérdida de la función en el gen supresor tumoral APC. El síndrome de Gardner es un tipo de PAF y está caracterizado por múltiples pólipos adenomatosos colónicos además de anormalidades extracolónicas como tumores desmoides, osteomas, lipomas, anormalidades dentales, quistes dermoides y adenomas duodenales. Este reporte tiene como propósito presentar dos casos referentes a PAF. El primer caso, trata de un paciente con osteomas e historia de hematoquezia, con diagnóstico de sindrome de Gardner posterior a la colonoscopia. El segundo caso es un paciente con historia familiar de cáncer de colon, que al examen colonoscópico se le diagnostica PAF con adenocarcinoma tubular bien diferenciado. Se decide reportar los casos debido a que son los primeros reportes en el Perú sobre esta entidad

Familial Adenomatous polyposis (FAP) it is based on an autosomal dominant mutation which results in loss of function of the APC tumor suppressor gene. On the other hand, Gardner syndrome is a type of FAP and is characterized for multiple colonic adenomatous polyps and extracolonic abnormalities as desmoid tumors, osteomas, lipomas, dental abnormalities, dermoid cysts and duodenal adenomas. This report aims to present two patients with FAP: The first one is a patient who presented with osteomas and hematochezia, being diagnosed with Gardner Syndrome after the colonoscopy. The second patient has a family history of colon cancer, who is diagnosed with FAP with tubular adenocarcinoma. We decide to report both cases due to the absence of previous reports in Peru

RESUMO

Gardner's syndrome (GS) is a genetic disorder characterised by intestinal polyps, multiple osteomas, and soft-tissue tumours. Dentists play an important role in the syndrome diagnosis considering that craniomaxillofacial osteomas are a major criteria for Gardner's syndrome diagnosis. This study aimed to describe the main stomatological manifestation of GS and the importance of dentists in its diagnosis. Two patients presenting GS were evaluated. The first one had two osteomas in the mandible and GS was suspected. The colonoscopy confirmed the presence of polyposis and a prophylactic proctocolectomy was performed. The other patient had a late-stage diagnosis of GS and developed a rectum adenocarcinoma. The presence of craniomaxillofacial osteomas are a hallmark of the disease. Early-stage GS diagnosis may enable early diagnosis and preventive strategies in carriers. Other dental abnormalities, such as supernumerary teeth, hypercementosis and odontomas, can also be observed.

RESUMO

INTRODUCTION: Desmoid tumor (DT) is a common manifestation of Gardner's Syndrome (GS), although it is a rare condition in the general population. DT in patients with GS is usually located in the abdominal wall and/or intra-abdominal cavity. PRESENTATION OF CASE: We report a case of a 32 years-old female patient with familial adenomatous polyposis (FAP), who was already submitted to total colectomy and developed multiple DT, located in the abdominal wall and in the left breast. The patient underwent several surgical procedures, with a multidisciplinary team of surgeons. Wide surgical resections of the left breast and the abdominal wall tumors were performed in separate steps. Polypropylene mesh reconstruction and muscle flaps were needed to cover the defects of the thoracic and abdominal walls. After partial necrosis of the adipose-cutaneous flap in the abdomen that required a new skin graft, she had a satisfactory outcome with complete healing of the surgical incisions. DISCUSSION: DT is frequent in GS, however, breast localization is very rare, with few cases reported in the literature. Recurrence of DT is not negligible, even after a wide surgical resection. GS patients must be followed up closely, and clinical examination, associated with imaging studies, should be performed to detect any signs of tumor. CONCLUSION: DT represents one of the most significant causes of the morbidity and mortality that affects FAP patients following colectomy. In general, the surgical procedures to excise DT are highly complex, requiring a multidisciplinary team.

RESUMO

Gardner's syndrome (GS) is a hereditary disorder characterized by multiple osteomas, enostosis, epidermoid cysts, subcutaneous desmoid tumors and multiple gastrointestinal polyps. Given the variety of clinical manifestations, the triad of symptoms that better characterizes the GS is composed by polyps of the colon, multiple osteomas and tumors of soft tissue. The osteomas are most common in the frontal bone and mandible. A significant feature of GS is the progression to malignancy of the intestinal polyps in almost 100% of patients. Early detection of GS allows for an excellent prognosis and may be a lifesaving event. Thus, the aim of this case report was to describe the radiographic aspects of GS in the dentomaxillofacial region and to discuss with the current scientific literature.

A síndrome de Gardner (SG) é uma desordem caracterizada por múltiplos osteomas, enostosis, cistos epidermoides, tumores desmoides subcutâneos e múltiplos pólipos gastrointestinais. Considerando a variedade de manifestações clínicas, a tríade dos sintomas que melhor caracterizam a SG é composta por pólipos do cólon, múltiplos osteomas e tumores de tecido mole. Os osteomas são mais comuns no osso frontal e mandíbula. Uma característica significativa da SG é a progressão maligna dos pólipos intestinais em aproximadamente 100% dos pacientes. A detecção precoce da SG favorece um excelente prognóstico e pode salvar vidas. Então, o objetivo deste relato de caso foi descrever os aspectos radiográficos da SG na região dento-maxilo-facial e discutir com a literatura científica atual.

RESUMO

Gardner syndrome (GS) is a rare entity characterized by a triad of familial colonic polyposis, multiple osteomas and soft tissue tumors, including desmoid tumor (DT). This is a case report of a 30 year-old patient with GS who developed giant DT in the abdominal wall after undergoing several laparotomies. The patient has taken a long time to search for medical care, and at first he saw another team that refused to operate him by judging the lesion unresectable. The surgery in our department was performed in three steps. Initially, we resected the lesion with macroscopic margins, and as there were small bowel adhesions in the tumor, we performed enterectomy and closed using the "Bogotá" technique, with skin closure on the bag. On the fourth postoperative day (POD), we reoperated the abdomen without identifying any signs of fistula. On the seventh POD there was another surgical intervention, this time to insert a double-sided mesh. The patient recovered well, and had no debilitating motor deficit, despite the extensive resection of the abdominal muscles. Curative treatment of DT is based on surgical resection and only sequential surveillance allows us an early diagnosis, when the lesion is still resectable. (AU)

Tumor desmoide gigante de parede abdominal em paciente portador da Síndrome de Gardner. A Síndrome de Gardner (SG) é uma entidade rara caracterizada pela tríade polipose colônica familial, múltiplos osteomas e tumores de tecidos moles, dentre eles o tumor desmoide (TD). Tratou-se de um relato de caso de um paciente de 30 anos, com SG que evoluiu com TD gigante em parede abdominal, após ser submetido a diversas laparotomias prévias. O paciente levou longo tempo para procurar o serviço de cirurgia, passando por outra equipe que se negou a abordá-lo por julgar a lesão irressecável. A cirurgia no nosso serviço se deu em três tempos. Inicialmente, foi feita a ressecção da lesão com margens macroscópicas e, por haver aderências de alças no tumor, realizamos enterectomia e fechamos a Bogotá com síntese da pele sobre a bolsa. No quarto dia pós-operatório (DPO), reabordamos o abdômen sem identificar sinal de fístula. No sétimo DPO houve nova abordagem, agora para colocar tela dupla face. O paciente evoluiu bem, sem déficit motor debilitante, apesar da extensa área de ressecção muscular abdominal. O tratamento curativo dos TD é baseado na sua ressecção cirúrgica e somente a vigilância sequencial nos permite seu diagnóstico precoce e a abordagem enquanto a lesão é ressecável. (AU)

RESUMO

El síndrome de Gardner, una variante de la poliposis adenomatosa familiar, es una enfermedad hereditaria autosómica dominante caracterizada por la presencia combinada de múltiples pólipos intestinales y manifestaciones extraintestinales que incluyen osteomas múltiples, tumores del tejido conectivo carcinoma de tiroides hipertrofia del epitelio pigmentado de la retina, también son frecuentes la presencia de dientes supernumerarios retenidos y odontomas. Se presenta un caso clínico de un paciente masculino, de 20 años de edad que acude a consulta por presentar aumento de volumen en tres localizaciones de la región facial. Radiográficamente se constataron las imágenes radiopacas características del osteoma y con la rectosigmoidescopia la presencia de pólipos intestinales. La intervención quirúrgica de los osteomas se realizó bajo anestesia general que incluyó condilectomía del lado izquierdo. El diagnóstico histopatológico fue de osteoma ebúrneo. Un año después del procedimiento se observó clínicamente recuperación estética y funcional y radiográficamente buena regeneración ósea en al ángulo mandibular donde se encontraba el osteoma de mayor diámetro. El paciente ha tenido hasta la actualidad una evolución muy satisfactoria, con excelente apertura bucal. El objetivo es describir el manejo que se tuvo con un paciente con síndrome de Gardner en el Servicio de Cirugía Maxilofacial de Artemisa(AU)

Gardner's syndrome, a variant of familial adenomatous polyposis, is a dominant autosomal inherited disease characterized by multiple intestinal polyps together with extra-intestinal manifestations including multiple osteomas, connective tissue tumors, thyroid carcinomas, hypertrophied pigmented epithelium of the retina, and also frequent retained supernumerary teeth and odontomas. The objective of this paper was to describe the management of a patient with Gardner's syndrome at the maxillofacial surgery service in the province of Artemisa. The clinical case of a male patient aged 20 years, who went to the maxillofacial service on account of increased volume of the facial area in three sites. The X-rays showed radiopaque images characteristic of osteomas whereas rectosigmoidoscopy revealed intestinal polyps. The osteomas were surgically removed under general anesthesia including condylectomy on the left side. The histological-pathological diagnosis was osteoid osteoma. One year after the surgical procedure, the clinical exam showed esthetic and functional recovery and the radiographies disclosed good bone regeneration in the mandibular angle where the biggest osteoma was found. The patient has recovered very satisfactorily, with excellent oral opening(AU)
