ABSTRACT
O bócio retroesternal é uma afecção rara da glândula tireóide, que acomete principalmente mulheres acima de 60 anos, caracterizada por tireóide aumentada de tamanho, peso e volume, que invade a cavidade torácica total ou parcialmente. A não realização do ato cirúrgico tem sido preconizada em alguns casos como forma alternativa de melhoria da qualidade de vida, sobretudo em pacientes idosos assintomáticos. Todavia, existe uma incidência de câncer nos bócios retroesternais, associado a um índice maior de complicações, que justifica a abordagem cirúrgica precoce, principalmente em pacientes jovens, mesmo que assintomáticos. Este trabalho resulta de um relato de caso e revisão de literatura, sobre bócio retroesternal e incidência de câncer em uma paciente de 62 anos, submetida a tireoidectomia total, com achados histopatológicos de pós operatório, de carcinoma papilífero, carcinoma folicular e adenoma folicular. Esses achados nos alerta para a possibilidade de incidência de câncer nesses pacientes, devendo ser aventado o tratamento cirúrgico precoce. (AU)
The retrosternal goiter is a rare thyroid gland disease, which mainly affects women over 60 years, characterized by increased thyroid size, weight and volume, which invades the thoracic cavity. Failure to perform the surgery has been recommended in some cases as an alternative way of improving the quality of life, especially in asymptomatic elderly patients. However, there is an incidence of cancer in retrosternal goiters associated with a higher rate of complications, justified the early surgical approach, especially in young patients, even if asymptomatic. This work results from a case report and literature review on retrosternal goiter and cancer incidence in a 62-year-old patient submitted total thyroidectomy with histopathologic findings after surgery, papillary carcinoma, follicular carcinoma and follicular adenoma. These findings alerts us to the possibility of cancer incidence in these patients, recommending in such cases, early surgical treatment.

BACKGROUND: Dermatomyositis and polymyositis are both types of idiopathic inflammatory myositis characterized by inflammation and weakness of proximal skeletal muscles and skin rash. CASE: A 49-year-old Caucasian woman recently diagnosed with breast cancer classified as T1N2M0, stage IIIA, presenting skin rash associated with heliotrope and Gottron's papules. In addition, there was a progression to a severe reduction in proximal muscle strength with severe dysphagia. The initial treatment was conducted, and the patient recovered from all symptoms and followed adjuvant cancer management. TREATMENT: At first, high dose of corticosteroid was administered as pulse therapy, and a radical mastectomy was indicated due to the severe symptoms of the paraneoplastic syndrome. Then chemotherapy and radiotherapy were applied, and oral corticoid associated with immunosupressive drug was administered for dermatomyositis control. DISCUSSION: The association between myositis and an increased risk of cancer has been demonstrated over the years. This patient has a high probability of dermatomyositis diagnosis. The initial treatment with high dose of glucocorticoids may result in an improvement of muscle lesions. Second-line treatment with azathioprine, methotrexate, or cyclophosphamide may be required for aggressive disease. Removal of the cancer induces improvement of paraneoplastic syndrome. CONCLUSION: Dermatomyositis can be a clinical manifestation of a paraneoplastic syndrome in patients with breast cancer. It is a rare diagnosis, and there is little evidence to guide treatment until now. It is possible to control the evolution of dermatomyositis with high doses of glucocorticoids in almost all cases; however, in severe cases of paraneoplastic syndrome, cancer treatment should start immediately.

Aneurysms and thromboses of the portal vein are rare pathologies of the portal system that commonly follow an asymptomatic course. The vast majority of cases are diagnosed as incidental findings during imaging studies. Symptoms of aneurysms are the result of mass effects, while thrombosis symptoms are a function of the liver's ability to form a collateral circulation network in the thrombosis. The scant experience with such cases poses a dilemma for patient management and so the vast majority of authors choose an expectant approach with rigorous patient surveillance and only intervene in symptomatic patients. We report one case of an aneurysm of the portal vein and one case of portal vein thrombosis and discuss management and observation of these patients...
O aneurisma e a trombose de veia porta são doenças raras do sistema porta, que comumente cursam sem sintomas. A grande maioria dos pacientes é diagnosticada com achados em exames de imagem. Os sintomas são atribuídos ao efeito de massa, no caso do aneurisma, e relativos à capacidade hepática de formar uma rede de circulação colateral, no caso da trombose. A escassa experiência nesses casos representa um dilema na abordagem desses pacientes e, portanto, a grande maioria dos autores opta por seguimento rigoroso e a intervenção é indicada apenas para os pacientes sintomáticos. Neste trabalho, relatamos um caso de aneurisma de veia porta e outro de trombose da veia porta, propondo o manejo e o acompanhamento desses pacientes...
