Watermelon Stomach, Hemorrhagic Pericarditis, Small Cell Carcinoma of the Lung and Synchronous Squamous Cell Carcinoma of the Tongue Base

Based on a case of gastric antral vascular ectasia (watermelon stomach) that was associated with hemorrhagic pericarditis, small cell lung carcinoma with mediastinal lymph node metastases and a synchronous squamous cell carcinoma of the base of the tongue, the authors made a review of the clinical, endoscopic and histopathological aspects of this type of gastropathy, and its association with other diseases, and of the results of its endoscopic therapy. The causes of hemorrhagic pericarditis are considered, emphasizing the necessity to know if the effusion has a malignant etiology. To the best of our knowledge the association of watermelon stomach to small cell lung carcinoma and squamous cell carcinoma of the base of the tongue has not yet been described. Extensive metastases to mediastal lymph nodes are common to small cell lung carcinoma.

A Utilização de Endopróteses na Síndrome da Veia Cava Superior por Neoplasia do Pulmão

Apresentam-se seis casos de síndrome da veia cava superior causado por neoplasia do pulmão e que foram tratados por endopróteses colocadas por via percutânea. Descreve-se a técnica e avaliam-se os resultados. Num caso ocorreu trombose aguda da endoprótese que foi tratada por uroquinase. Não se registaram outras complicações. Um doente faleceu 1 mês depois por progressão da doença. Os restantes mantinham-se sem queixas de síndrome da veia cava superior durante mais do que 6 meses. Conclui-se que a colocação de endopróteses é uma técnica pouco invasiva, eficaz e com melhoria imediata no síndrome da veia cava superior.

Utilidade da Broncofibroscopia no Diagnóstico de Neoplasia do Pulmão em Doentes com Pneumonia Arrastada

A broncofibroscopia (BF) é frequentemente efectuada em doentes com pneumonias de evolução arrastada com o objectivo de excluir patologia endobrónquica de etiologia neoplásica. Dado que a resolução radiográfica das pneumonias da comunidade é variável, sendo dependente de vários factores (agente etiológico, idade, doenças associadas) a decisão para efectuar uma BF é muitas vezes empírica. Com o objectivo de descrever a nossa experiência neste problema estudámos retrospectivamente 123 doentes com o diagnóstico de pneumonia da comunidade baseado em critérios clínicos e radiográficos e que, apesar da antibioferapia considerada adequada, não apresentavam melhoria radiográfica significativa ao fim de pelo menos 2 semanas. Obtivemós um diagnóstico histológico de neoplasia maligna do pulmão em 7 doentes (5,6° o), sendo todos do sexo masculino, com idade superior a 55 anos efuínadores de pelo menos 40 U.M.A. A análise comparativa com os restantes doentes mostrou diferenças com significado~estatístico em relação à idade e ao consumo tabágico. O tempo de evolução da doença,valores médios de hemoglobina, leucocitos, VS, existência ou não de alterações da função renal ou hepática não foram significativamente diferentes nos dois grupos. Concluimos que a BF deve ser efectuada precocemente nos doentes pertencentes ao grupo de risco identificado (fumadores, com mais de 55 anos) não se justificando a sua realização nos restantes doentes antes das 4 a 8 semanas de evolução, a menos que estejam presentes critérios clínicos objectivos tais como progressão da doença ou agravamento do estado geral.

Multiple Haemangiomas, Diaphragmatic Eventration and Beckwith-Wiedemann Syndrome: An Unusual Association

A 6-month-old girl with Beckwith-Wiedemann syndrome, multiple haemangiomas (axillary, laryngeal, pulmonary and hepatic) and diaphragmatic eventration was reported. All tumours responded to treatment with propranolol. The surgical correction of diaphragmatic eventration was crucial to a better outcome.

Henoch-Schönlein Purpura Associated with Pulmonary Adenocarcinoma

Introduction: The Henoch-Schönlein purpura (HSP) is an immunoglobulin A (IgA)-mediated smallvessel systemic vasculitis, rare in adults. The association with solid tumours has been described, especially with lung cancer. Case Report: We present the case of a 60-year-old Caucasian male, diagnosed with lung adenocarcinoma that underwent surgical resection without (neo)adjuvant theraphy. Two months latter he was admitted for abdominal pain, purpuric rash on his lower extremities and acute kidney injury, with serum creatinine (Scr) of 2 mg/dl. Urinalysis revealed haematuria and 24h proteinuria (P24h) of 1.5 g. The serum protein electrophoresis, complement components C3 and C4, circulating immune complexes, cryoglobulins, ANCA, ANA, anti-dsDNA and the remaining immunologic study as screening for viral infections (HCV, HBV and HIV) were negative. Renal ultrasound was normal and kidney biopsy revealed mild mesangial proliferation; 2 cellular glomerular crescents and 1 fibrinoid necrosis lesion; large amounts of red blood cell casts; lymphocytic infiltration in the intertubular interstitial capillaries; moderate arteriolar hyalinosis. Immunofluorescence demonstrated mesangial and parietal deposits of IgA. The diagnosis of HSP was assumed, and the patient started prednisolone 1 mg/kg/day. Ten months after diagnosis the patient’s baseline Scr is 1.4 mg/dl with P24h of 0.18g, without haematuria. Conclusion: Although this is a rare association and the exact mechanism behind the disease is yet unknown, physicians should be aware of it. The early recognition and treatment may prevent renal disease progression.

Budesonide Reverses Lung Hyperinflation in Childhood Asthma: a Controlled Study

Budesonide (800 mg bid, for 2 months) was administered to 12 asthmatic children (mean age, 11.293.3 years) with lung hyperinflation (TGV]130% predicted and:or RV]140% predicted) in a randomised, placebo controlled, double blind, crossover study. Body plethysmography (panting frequency controlled at 1·s 1) was performed at the beginning, 2 months afterwards (before crossover) and at the end of the study. Budesonide significantly reduced TGV (2.3590.90 l BTPS or 126924% predicted) compared with placebo (2.5491.08 l BTPS, P 0.014 or 140921% predicted, PB0.05). In addition, budesonide significantly increased mean specific conductance (0.0690.02 cm H2O 1 l s 1 to 0.0790.01 cm H2O 1 l s 1, PB0.05). It was concluded that budesonide reduced lung hyperinflation most likely by decreasing airway inflammation.

Pancreatic Involvement by Plasma Cell Neoplasms

INTRODUCTION: Pancreatic involvement by plasma cell neoplasms is an extremely rare event, with only 50 cases described in the literature. They can present as a primary solitary extramedullary plasmacytoma or plasmacytoma secondary to a plasma cell myeloma. Clinical manifestations are due to the presence of a pancreatic mass usually in the pancreas head, which causes extra-biliary obstruction and abdominal pain. METHODS: Abdominal imaging including CT scan or endoscopic ultrasound with fine-needle aspiration tissue sampling is essential for the initial diagnostic procedure. However, immunohistochemical analysis of the biopsy specimen or flow cytometry of the aspirated material is crucial to prove the monoclonality and the final diagnosis of a plasma cell neoplasm. DISCUSSION: Management of these situations include radiotherapy, chemotherapy, surgery or combined therapy. Novel medications including the immunomodulatory drugs or the proteasome inhibitors followed by consolidation with intensive chemotherapy and haematopoietic stem cell transplantation are nowadays used as upfront treatment in the cases associated to a plasma cell myeloma. CONCLUSION: Despite the rarity, plasma cell neoplasms should be considered in the differential diagnosis of obstructive jaundice and pancreatic neoplasms since they are potentially treatable situations.
