Tracheal metastasis of lung adenocarcinoma

A 46-year-old female presented with dyspnea, dysphagia, and throat irritation with a diagnosis of tracheal metastasis resulting from a previously resected lung adenocarcinoma. Upper airway metastasis has a poor prognosis and is rarely observed. The clinical presentation manifests with cough and hemoptysis in most cases. Treatment includes surgical metastatic removal associated with combined radiotherapy and chemotherapy.

The presence of metastases in regional lymph nodes is associated with tumor size and depth of invasion in sporadic gastric adenocarcinoma / A presenca de metastases em linfonodos regionais esta associada ao tamanho tumoral e profundidade de invasao no adenocarcinoma gastrico esporadico

Background: Gastric adenocarcinoma is more often found in men over 50 years in the form of an antral lesion. The tumor has heterogeneous histopathologic features and a poor prognosis (median survival of 15% in five years). Aim: To estimate the relationship between the presence of nodal metastasis and other prognostic factors in sporadic gastric adenocarcinoma. Method: Were evaluated 164 consecutive cases of gastric adenocarcinoma previously undergone gastrectomy (partial or total), without clinical evidence of distant metastasis, and determined the following variables: topography of the lesion, tumor size, Borrmann macroscopic configuration, histological grade, early or advanced lesions, Lauren histological subtype, presence of signet ring cell, degree of invasion, perigastric lymph node status, angiolymphatic/perineural invasion, and staging. Results: Were found 21 early lesions (12.8%) and 143 advanced lesions (87.2%), with a predominance of lesions classified as T3 (n=99/60, 4%) and N1 (n=62/37, 8%). The nodal status was associated with depth of invasion (p<0.001) and tumor size (p<0.001). The staging was related to age (p=0.048), histological grade (p=0.003), and presence of signet ring cells (p = 0.007), angiolymphatic invasion (p = 0.001), and perineural invasion (p=0.003). Conclusion: In gastric cancer, lymph node involvement, tumor size and depth of invasion are histopathological data associated with the pattern of growth/tumor spread, suggesting that a wide dissection of perigastric lymph nodes is a fundamental step in the surgical treatment of these patients. .

Racional: O adenocarcinoma gástrico é encontrado mais frequentemente em homens acima de 50 anos sob a forma de lesão antral. A neoplasia apresenta características histopatológicas heterogêneas e prognóstico ruim (sobrevida média de 15% em cinco anos). Objetivo: Estimar a relação entre a presença de metástases nodais e demais fatores prognósticos no adenocarcinoma gástrico esporádico. Método: Foram avaliados 164 casos consecutivos de adenocarcinoma gástrico previamente submetidos à gastrectomia (parcial ou total), sem evidências clínicas de metástase à distância, sendo determinadas as seguintes variáveis: topografia da lesão, tamanho tumoral, configuração macroscópica segundo Borrmann, grau histológico, lesão precoce ou avançada, subtipo histológico segundo Lauren, presença de células em anel de sinete, grau de invasão, status dos linfonodos perigástricos, invasão angiolinfática/perineural e estadiamento. Resultados: Foram encontradas 21 lesões precoces (12,8%) e 143 avançadas (87,2%) com predomínio de lesões T3 (n=99/60,4%) e N1 (n=62/37,8%). O status nodal esteve associado à profundidade de invasão (p<0,001) e tamanho tumoral (p<0,001). O estadiamento esteve relacionado à idade (p=0,048), grau histológico (p=0,003) e presença de células em anel de sinete (p=0,007), invasão angiolinfática (p=0,001) e invasão perineural (p=0,003). Conclusão: No adenocarcinoma gástrico, o envolvimento linfonodal, o tamanho tumoral e a profundidade de invasão são dados histopatológicos associados ao padrão de crescimento/disseminação neoplásico, sugerindo que a dissecção ampla de linfonodos perigástricos seja etapa fundamental ...

Hipertensão intracraniana relacionada a um raro padrão de neoplasia: gliomatose cerebral / Intracranial hypertension related to a rare pattern of neoplasm: gliomatosis cerebri

Gliomatose cerebral (GC) é um raro padrão de crescimento dos gliomas cerebrais, que infiltra difusamente os hemisférios cerebrais e estruturas adjacentes. As características radiológicas e histopatológicas são fundamentais para estabelecer ante mortem o diagnóstico. Em geral, a GC corresponde a uma neoplasia com diferenciação astrocítica e de grau histológico III / alto grau, a qual apresenta um curso clínico variável. No presente relato, os autores apresentam um caso de GC determinando hipertensão intracraniana, descrevem os principais achados histopatológicos e o diagnóstico diferencial desta neoplasia pouco frequente (AU)

Gliomatosis cerebri (GC) is a rare growth pattern of brain gliomas, which diffusely infiltrates the cerebral hemispheres and adjacent structures. Radiological and histopathological characteristics are key to establish ante-mortem diagnosis. In general, GC corresponds to a neoplasm with astrocytic differentiation and histological grade III/high degree, which presents a variable clinical course. In this report, the authors present a case of GC determining intracranial hypertension and describe the main histopathological findings and the differential diagnosis of this uncommon neoplasm (AU)
