primary neuroendocrine carcinoma (nec) of the mediastinum is a rare type of carcinoma. according to the literature, only five cases of this condition have been reported so far. in this paper, we present a rare case of mediastinal nec of unknown primary site. the patient was a 34-year-old man with mediastinal nec, who presented with chronic dry cough and a right-sided mediastinal mass one year p...

Most mediastinal tumours and cysts follow a definite pattern due to their site of origin and the effect upon neighbouring structures of their enlargement. A small number deviate from the usual picture, and it was felt that the examination of a large series might disclose enough of these variants to enable some contribution to be made to the basic aetiology and diagnosis of these tumours. The pr...

conclusions our data showed that the amount of hydration, transfusion, pre-manipulation arrhythmia, and pulmonary function should be controlled to decrease the risk of arrhythmias. minor mediastinal manipulation, few intraoperative hemorrhages, improvement of pulmonary function, and careful blood pressure monitoring can reduce the risk of hypotension. patients and methods in this prospective st...

Mediastinal compression syndrome is a commonly seen entity. Mediastinal compression, mostly due to a space-occupying lesion, is distinct and different from mediastinitis/mediastinal fibrosis, which could also lead to superior vena cava syndrome. Idiopathic mediastinal fibrosis should also be considered as differential diagnosis of mediastinal structures with various radiological, CT and MRI and...

OBJECTIVE To determine whether mediastinal lymph node dissection improves survival compared with mediastinal lymph node sampling in patients undergoing resection for N0 or nonhilar N1, T1, or T2 non-small cell lung cancer. METHODS Patients with non-small cell lung cancer underwent sampling of 2R, 4R, 7, and 10R for right-sided tumors and 5, 6, 7, and 10L for left-sided tumors. If all tumors w...

INTRODUCTION Metachronous mediastinal lymph node metastasis without pulmonary metastasis is extremely rare in colorectal cancer, which makes the clinical diagnosis difficult and treatment strategy unclear. PRSENTATION OF CASE A case was a 59-year-old man, who had undergone right hemicolectomy for ascending colon cancer 2 years and 8 months previously, presented with enlarged mediastinal lymph...

background esophageal, stomach, and colorectal cancers are commonly lethal gastrointestinal tract (git) neoplasms, causing almost two million deaths worldwide each year. some environmental risk factors are acknowledged; however, genetic defects can significantly contribute to predisposition to git cancers. accordingly, recent works have shown that single-nucleotide polymorphisms (snps) within m...

case presentation a 43-year-old man was referred to our institution for a severe aortic regurgitation and an ascending aorta enlargement associated with a relapsing sub-aortic membrane, which had been treated in his childhood. he underwent a redo ascending aorta replacement and an aortic valve replacement (mechanical prosthesis) along with a resection of the relapsing sub-valvular membrane. som...

mediastinal lymphangioma is primarily a benign lesion and the majority of the cases are found incidentally. these lesions account for approximately 1% of all mediastinal tumors. here we present a giant mediastinal cystic mass in a 35-year-old female who was presented with severe respiratory distress. on the plain chest radiography and ct scan, a massive left pleural effusion with large paraster...
