Between April 1992 and April 1993, we performed fifty-four mediastinal biopsies in 51 patients with a mediastinal mass. Nine of these had lung cancer with mediastinal lymphadenopathy, and the remaining 42 had various primary mediastinal lesions. We have performed twenty video-assisted thoracic surgical procedure, twenty-six mediastinoscopies, and eight(More)
BACKGROUND Thymomas are a heterogeneous group of tumors. Treatment of invasive lesions is not well standardized. The aim of this study is to propose a clinicopathologically based protocol for multimodality therapy. METHODS Between 1965 and 1988, we operated on 83 patients with thymoma who did not receive standardized adjuvant therapy. In 1989, on the(More)
In this study the authors have investigated the clinicopathologic correlations in 80 consecutive cases of thymoma in order to establish the clinical usefulness of histologic subtyping of these tumours. All cases were histologically examined and classified according to Salyer and Eggleston and to Marino and Müller-Hermelink classifications. Therefore,(More)
The prognostic value of four clinical variables (age and sex of patients, association with myasthenia gravis, and clinical stage) and histological type was analyzed in 83 consecutive patients with thymoma, histologically classified as cortical, medullary, and mixed. Age, sex, and association with myasthenia gravis did not prove to represent significant(More)
Between January 1986 and January 1991, 175 patients with suspected T3 or T4 bronchogenic carcinoma underwent computed tomographic (CT) examination of the chest before thoracotomy. We considered two groups of patients: group 1 includes 98 patients with a paramediastinal mass on standard chest X-ray; invasion of hilar and mediastinal structures was(More)
OBJECTIVE Patients undergoing pulmonary resections often present postoperative air leaks of varying magnitude and duration; this complication is more frequent with incomplete or absent interlobar fissures. Small leaks close spontaneously within 5-7 days; larger leaks may persist longer and could be associated with increased morbidity and prolonged(More)
Rats of the Milan hypertensive strain (MHS) are resistant to both hypertensive and diabetic renal disease. Genetically determined hypertrophy of intrarenal arteries has been suggested as the putative mechanism preventing transmission of systemic hypertension to the glomerular microcirculation or diabetes-induced loss of autoregulation, which lead to(More)
A retrospective study of 28 cases of thymoma classified according to Marino and Müller-Hermelink (cortical, medullary, mixed common, mixed with cortical predominance, mixed with medullary predominance thymoma) was undertaken to determine the existence of correlations between histology and clinical behavior. Cortical thymoma was observed in 11 cases (39.2%),(More)
BACKGROUND The incidence of lung cancer is increased in patients with bullous emphysema. METHODS A series of 95 patients undergoing excision of bullous lung tissue was reviewed to determine the incidence and long term outcome of occult carcinoma present in the resected material. RESULTS Four patients (4.2%) had peripheral foci of large cell carcinoma in(More)
In this report, we describe the clinicopathological features of 4 patients with true thymic hyperplasia. This controversial thymic lesion has only recently been defined as a variable, often massive enlargement of the thymus characterized by a nearly normal microscopic structure. Our study of 4 patients and review of the literature indicate that true thymic(More)
