Thoracoplasty was invented for removing cavities between thoracic wall and remnant lung or mediastinum. It was initially used in cases of tuberculosis or unspecific infections, while currently it is used mainly for space problems after lobectomy/pneumonectomy.This article presents an overview of the historical and current techniques of this surgical procedure.Nowadays, thoracoplasty is rarely performed due to the low incidence of diseases for which this method is necessary. Therefore, this method has even been discredited...

BACKGROUND: Lung stereotactic body radiotherapy (SBRT) is considered a standard curative treatment for medically inoperable early stage non-small-cell lung cancer (NSCLC). Patients with ultracentral tumors (signifying tumors whose planning target volume touches or overlaps the central bronchial tree, esophagus, or pulmonary artery) may be at higher risk of serious toxicities such as bronchial stricture and collapse, esophageal strictures, tracheal-esophageal fistula, and hemorrhage. The primary objective of the study is to determine the maximum tolerated dose of radiotherapy for ultracentral NSCLC...

Castleman disease is a lymphoproliferative disorder with unknown etiology and pathogenesis. While the disease may involve all parts of the body, the mediastinum appears to be the most common part of involvement. In this study, we present two cases of Castleman disease with different localizations that mimicked malignancy. A 62-year-old female patient presented with jaundice. Laboratory analysis indicated aspartate aminotransferase: 250 U/L, total bilirubin: 4 mg/dl, and carbohydrate antigen (CA) 19-9: 900 U/ml...

The patient was a 66-year-old man who had treated with bronchiectasis. He was admitted to our hospital because of hemoptysis. A chest plain computed tomography (CT) showed bronchiectasis in the left lower lobe and nodular lesion in the mediastinum. Chest contrast CT revealed a left bronchial artery aneurysm, and hyperplastic left bronchial arteries dilating and winding toward the left lower lobe. We performed selective angiography of the bronchial artery, revealing an aneurysm, and we performed 3 times of bronchial arterial embolization( BAE)...

An 81-year-old woman with acute respiratory distress was referred to our hospital. Computed tomography showed a large mass in the upper mediastinum with severe tracheal stenosis. Endotracheal intubation was performed under the preparation of extracorporeal membrane oxygenation and high-frequency jet ventilation, and the tumor was completely removed. The pathologic diagnosis was a goiter. Post-operatively, respiratory distress disappeared. No tumor recurrences have been noted for more than 2 years after surgery...

We report a surgical case of micronodular thymoma with lymphoid stroma (MNT), which is a rare type of thymoma. A 66-year-old man was referred to our hospital for further examination and treatment of a nodule in the mediastinum. Computed tomography(CT) showed a 20-mm nodule in the anterior mediastinum, and positron emission tomography-CT showed slight uptake in the same region. Thymoma was suspected and videoassisted thymectomy was performed. Histopathological findings showed spindleshaped tumor cells forming storiform, with the background of lymphoid stroma, and the tumor was diagnosed as MNT...

BACKGROUND: The incidence of metachronous esophageal squamous cell cancer (ESCC) after head and neck cancer (HNC) and in elderly patients has increased. Both elderly ESCC patients and ESCC patients after HNC surgery are at potential risk for dysphagia, and for the latter, surgery in the neck is difficult. An intrathoracic anastomosis that bypasses the cervical procedure is preferable to preserve swallowing function and reduce surgical risk. In gastrectomized patients, because the stomach cannot be used as a substitute, securing graft blood supply is critical, but microvascular anastomosis cannot be easily added in procedures for intrathoracic posterior mediastinal reconstruction...

Left ventricular assist devices (LVADs) are currently the best alternative to cardiac transplantation for patients with end-stage heart failure (HF) as a bridge to transplant or to decision, or as destination therapy. Full median sternotomy or minimally invasive techniques are the more standard approaches used at present.  LVADs are usually implanted between the left ventricle apex and the ascending aorta. An implantation through a left thoracotomy with an outflow graft connected to the descending aorta is much less performed nowadays due to the longer times to extubation, higher incidence of postoperative pain, and poorer hemodynamics in the ascending aorta, which may lead to thrombosis...

A whitish mass approximately 30 mm in diameter was noted in the anterior mediastinum of a 67-week-old female Fischer 344 rat. Histopathologically, two types of tumor cells were identified on the basis of morphologic features: epithelial tumor cells with a tubular or cord-like growth pattern and rhabdomyosarcomatous tumor cells characterized by the presence of cross-striations. Immunohistochemically, the epithelial tumor cells reacted positively for cytokeratin AE1/AE3, and some reacted positively for p63, which is expressed in normal thymic epithelial cells...

A woman in her 70s with an 8.6-cm tumor in the anterior mediastinum underwent tumor excision by median sternotomy, which combined resection of the fifth and sixth ribs. The pathological diagnosis was myxofibrosarcoma, and pathologically curative resection was accomplished. Local recurrence was detected at 10, 19, 23 and 28 months after the initial surgery. After repeated surgical resection, radiation therapy for the fourth unresectable recurrence resulted in failure. She died 34 months after the initial surgery...

A teenage girl was evaluated for recurrent right pneumonia. The evaluation revealed a calcified mediastinal mass that compressed the right intermediate and middle lobar bronchi, as well as the right pulmonary artery and veins. The clinical picture together with imaging studies and borderline positive serology testing suggested a diagnosis of fibrosing mediastinitis associated with histoplasmosis. This rare condition is characterized by the local proliferation of invasive fibrous tissue within the mediastinum due to a hyperimmune reaction to Histoplasma capsulatum ...

RATIONALE: In the thorax, Hodgkin lymphoma (HL) most frequently involves the anterior mediastinal and paratracheal regions and tends to spread to contiguous nodal groups. Enlarged lymph nodes typically have homogeneous soft tissue attenuation similar to that of muscle tissue on computed tomography (CT). PATIENT CONCERNS: A contrast-enhanced CT examination of a 19-year-old man with right-sided chest pain showed an intense, heterogeneously enhancing mass with organization of serpentine and dilated blood vessels in the right anterior mediastinum that had invaded the upper lobe of the right lung...

Myxomas are the most common benign cardiac tumors and are located more frequently in the left atrium. In the literature there are cases describing the coexistence of thymic tumors and cardiac myxomas. In the case reported herein, during the resection of a cardiac myxoma, an enlarged thymus gland was encountered and resected. The histological exam revealed a thymic hyperplasia. The aim of this case study is to assess the need of conducting further studies in order to identify a common histological pathway between thymic lesions and cardiac myxomas...

Thymic carcinoma (TC) is a rare malignant tumor of the mediastinum with occult onset, rapid development, and poor prognosis. Surgery is the main treatment for early TC, but the majority of patients are diagnosed at Masaoka-Koga stage III or IV with local invasion or distant metastasis. Platinum and anthracyclines are currently considered key components of first-line chemotherapy for advanced TC; however, there are no standard treatment plans for patients who are refractory to first-line and further chemotherapy...

The pathophysiology of rapid eye movement sleep behavior disorder (RBD) associated with narcolepsy type 1 (NT1) is still poorly understood, potentially distinct from idiopathic RBD (iRBD), but may share affected common pathways. We investigated whether MIBG cardiac uptake differs between iRBD and NT1 comorbid with RBD. Thirty-four patients with NT1-RBD and 15 patients with iRBD underwent MIBG cardiac scintigraphy. MIBG uptake was measured by calculating the early and delayed heart to mediastinum (H/M) ratios...

BACKGROUND: Immature teratoma in a mediastinal location is a rare disease that might present as a valve pathology. Germ cell tumors with mediastinal locations account for up to 6% of immature teratoma cases. We present a case of an immature teratoma located primarily in the anterior mediastinum that manifested solely through symptoms of pulmonary stenosis. CASE PRESENTATION: We report a case of a 20-year-old white man with an immature teratoma who presented with progressive exertional dyspnea...
