Head and Neck Lymphomas in HIV Patients: a Clinical Perspective
2017
Introduction Because of the many HIV-related malignancies, the diagnosis and treatment of lymphoma in patients infected with human immunodeficiency virus are challenging. Objective Here, we review current knowledge of the pathogenesis, epidemiology, symptomatology, diagnosis, and treatment of head and neck lymphomas in HIV patients from a clinical perspective. Data Synthesis Although Hodgkin's lymphoma is not an AIDS-defining neoplasm, its prevalence is ten times higher in HIV patients than in the general population. NHL is the second most common malignancy in HIV patients, after Kaposi's sarcoma. In this group of patients, NHL is characterized by rapid progression, frequent extranodal inv…
Extranodal extension of lymph node metastasis is a marker of poor prognosis in oesophageal cancer: A systematic review with meta-analysis
2016
The extranodal extension (ENE) of nodal metastasis is the extension of neoplastic cells through the nodal capsule into the perinodal adipose tissue. This histological feature has recently been indicated as an important prognostic factor in different types of malignancies; in this manuscript, we aim at defining its role in the prognosis of oesophageal cancer with the tool of meta-analysis. Two independent authors searched SCOPUS and PubMed until 31 August 2015 without language restrictions. The studies with available data about prognostic parameters in subjects with oesophageal cancer, comparing patients with the presence of ENE (ENE+) versus only intranodal extension (ENE-), were considered…
Extranodal extension in N1-adenocarcinoma of the pancreas and papilla of Vater: A systematic review and meta-analysis of its prognostic significance
2016
The aim of the study was to investigate the prognostic role of extranodal extension (ENE) of lymph node metastasis in adenocarcinoma of the pancreas (PDAC) and papilla [cancer of the papilla of Vater (CPV)]. A PubMed and SCOPUS search from database inception until 5 January 2015 without language restrictions was conducted. Eligible were prospective studies reporting data on prognostic parameters in individuals with PDAC and/or CPV, comparing participants with the presence of ENE (ENE +) with those with intranodal extension (ENE). Data were summarized using risk ratios for number of deaths/recurrences and hazard ratios for time-dependent risk related to ENE+, adjusted for potential confounde…
Aportación al conocimiento clínico y prosnóstico de los Linfomas de Cabeza y Cuello
2015
Los linfomas son neoplasias del sistema linforreticular que asientan preferentemente en los ganglios linfáticos. Representan aproximadamente el 5% de todas las neoplasias malignas que se pueden desarrollar en la región anatómica de la cabeza y cuello. En general los Linfomas no Hodgkin son más frecuentes que los Hodgkin y suponen el 88% de todos los linfomas. En términos generales el modo de presentación más frecuente y común de estos tumores en esta región anatómica es la aparición de adenopatías cervicales Las manifestaciones extranodales aparecen en un 23-30% de los pacientes en los Linfomas no Hodgkin, siendo el anillo de Waldeyer la localización más frecuente. Por el contrario el Linfo…
Diagnostik eines hochmalignen B-Zell-Lymphoms des Dünndarms mit der Kapselendoskopie
2003
Wireless capsule endoscopy is a new diagnostic procedure to detect diseases of the small bowel, in particular in patients with obscure gastrointestinal bleeding. We report on a 76-year-old patient who presented at our hospital with signs of gastrointestinal bleeding and hypochromic anaemia. Bidirectional endoscopy, push enteroscopy, angiography as well as small bowel barium enema rendered no pathologic findings. Wireless capsule endoscopy demonstrated a polypous space in the cantral area of the small bowel. Subsequent intraoperative endoscopy revealed a subtotal stenosing tumour of the upper jejunum which was resected. Based on the histology a high-grade B-Cell lymphoma was diagnosed. The p…
Mercaptopurine Treatment in an Adult Man with Orbital and Intracranial Rosai-Dorfman Disease.
2016
Background. Rosai-Dorfmann disease (RDD) is a rare, idiopathic non-Langerhans cell histiocytosis, affecting children and young adults, that commonly presents as painless, massive cervical lymphadenopathy with fever, weight loss, and polyclonal hypergammaglobulinemia. Cervical lymphadenopathy and extranodal involvement are the main presentations. On the contrary, ophthalmic involvement and localisation in the central nervous system are rare.Case Report. An old man was admitted to our hospital for first seizure. Brain imaging studies revealed on the left an extra-axial thickening of the dura mater with enhancement and perilesional oedema, infiltrating the sphenoorbital fissure and an isointen…
