A 76-year-old woman complained of painful dysphagia and loss of weight. Esophagoscopy results were negative, whereas computed tomography (CT) disclosed a 25-mm mediastinal tumor without a connection to the esophagus. A diagnosis of nutcracker esophagus was made on high-resolution esophageal manometry. Peroral endoscopic esophageal myotomy failed to improve the symptoms. Right video thoracoscopy allowed resection of the tumor, which looked like a neurogenic tumor of the posterior mediastinum that developed from the right vagus nerve...

We report a rare case of mediastinal nonseminomatous germ cell tumor arising after 2 complete resections of mediastinal mature teratomas 18 and 10 years prior. After three cycles of chemotherapy for the mediastinal nonseminomatous germ cell tumor, the serum α-fetoprotein and β-human chorionic gonadotropin levels were normalized. However, chest radiography revealed that the mediastinal tumor had remarkably increased in size, and thus growing teratoma syndrome was diagnosed. The patient underwent urgent resection of the tumor, and a pathologic examination showed an encapsulated mature teratoma without any malignant viable cells...

BACKGROUND: Spontaneous pneumomediastinum (SPM) is classified as free air in the mediastinum in the absence of any precipitating cause. It is relatively uncommon, and the clinical significance and risk associated with SPM is not well understood and has not been widely documented in the literature. Our goals were to determine the outcomes of patients who presented with SPM and to determine predictors of severe pathology associated with SPM. METHODS: From 2004 through 2013, a retrospective review was conducted of patients who presented with SPM to our institution...

OBJECTIVES: The hemi-clamshell (HCS) approach consists of partial sternotomy with antero-lateral thoracotomy. This study evaluated the utilities and outcomes of the HCS approach in advanced lung cancer patients. METHODS: We retrospectively investigated 45 patients who underwent surgery for advanced lung cancer via the HCS procedure between 2000 and 2014, the indications for surgery being tumour invasion extending to the aorta arch in 5, descending aorta in 9, main pulmonary artery in 5, superior vena cava in 6, right or left atrium in 4, apical thoracic dome in 7 patients and mediastinal lymphadenopathy for left-sided lung cancer in 12...

Primary neuroendocrine tumors (NETs) of the mediastinum are very rare. Prognosis is usually poor despite treatment options. We present the case of a primary atypical carcinoid tumor of the mediastinum successfully treated by multimodal approach. A 50-year-old man presented for asthenia, dyspnea, and substernal sense of weight for two weeks. A chest-CT scan revealed a tumor mass of 107×55×95 mm(3) localized in the anterosuperior mediastinum compressing both brachiocephalic veins, the superior vena cava, the pericardium, and lungs...

Thymic carcinoma is a rare mediastinum malignant tumor derived from thymic epithelial cells. With the exception of complete resection, an effective therapy has not been established to date for advanced or relapsed thymic carcinoma. The present study examined the protein expression of excision repair cross-complementation group 1 (ERCC1) and class III β-tubulin (TUBB3), which are consider to be indicators of the anticancer activity of platinum-based and taxane-based chemotherapy, respectively. The expression of ERCC1 and TUBB3 proteins was examined in 40 thymic carcinoma patients who underwent either surgical resection or core-needle biopsy...

Dermatofibrosarcoma protuberans (DFSP) is a locally invading tumor, characterized by the presence of the collagen type I α 1 (COL1A1)-platelet-derived growth factor (PDGF) β fusion gene. We herein report the case of a 31-year-old man with a history of resection of an abdominal wall DFSP. The patient presented with chest pain and a computed tomography scan revealed a large mass in the posterior mediastinum and another mass in the right lung. The mediastinal mass was a sarcomatous lesion expressing the COL1A1-PDGFβ fusion gene, suggesting that it represented a metastasis of the DFSP following fibrosarcomatous (FS) transformation...

Postoperative hiatal hernia after esophagectomy occurs with a frequency of 0.4-6%, and the local conditions following esophagectomy promote its occurrence. In the material presented here, hiatal hernia in the form of displacement of the colon to the mediastinum was established in 0.78% (2/256) of all performed esophagectomies. Both cases were reoperated successfully.

A 50-year-old male was admitted to Intensive Care Unit with head and chest injury needed multiple central venous catheter (CVC) for the long-term intravenous access. Right internal jugular vein was cannulated uneventfully, and the tip of CVC was confirmed in the chest radiograph along the right border of the mediastinum. After few days, left subclavian vein was cannulated and the procedure was uneventful. However, the postprocedure Chest X-ray showed the CVC along the left border of mediastinum rather than the right border...

BACKGROUND Solitary fibrous tumors of the middle mediastinal space are uncommon and often not discovered until symptoms secondary to compression of adjacent structures occur. Diagnosis requires surgical biopsy and histological tissue analysis. We describe the ECHO appearance of the solitary fibrous tumor and successful non-invasive EBUS diagnosis. This method of diagnosis allowed for surgical planning for resection and allowed us to exclude non-surgical diseases, such as small cell carcinoma. CASE REPORT A 32-year-old man presented to his primary care physician with worsening intermittent chronic chest pain with recent progressive dysphagia, cough, and dyspnea...

BACKGROUND: The optimal therapy in patients with heart failure preserved ejection fraction (HFpEF) and hypertension (HT) has not been revealed. The beta blocker (BB) and the renin angiotensin aldosterone system inhibitor (RAAS-I) are recommend as class IIa in patients with HFpEF. The calcium channel blocker (CCB), a major anti-hypertensive drugs in Japan, is also recommend as class IIa in patients with HFpEF. However, the difference between azelnidipine, an L type CCB, and cilnidipine, an N type CCB, is unclear...

Ectopic thyroid is a rare congenital embryonic anomaly. Ectopic thyroid tissue can be located anywhere during its descent, but it is found primarily at the base of the tongue and in the mediastinum. It is very rarely found in the heart. Here, we report a rare case of cardiac ectopic thyroid tissue in a 53-year-old woman who presented with chest pain. Echocardiography revealed an intracardiac mass that was removed successfully. Histopathology confirmed that the mass was thyroid tissue without malignancy.

The following report describes the case of a 43-year-old male smoker that was referred to the rapid access lung clinic with haemoptysis, chest pain, and axillary lymphadenopathy-a clinical picture that raised concern for a possible underlying malignancy. Preliminary investigations revealed elevated D-dimers, low-volume haemoptysis, and a normal chest X-ray, which lowered the index of suspicion. However, computed tomography (CT) pulmonary angiogram identified a right hilar mass, several parenchymal cysts, and a large mediastinal mass...

71-year-old woman was pointed out to have an asymptomatic mediastinal tumor. Chest computed tomography(CT) showed a well-demarcated mass measuring 7 cm in diameter in the anterior mediastinum. We resected the mass through a median sternotomy. The tumor had a clear margin without invasion to the surrounding tissue and did not show continuity with the cervical thyroid gland. Histopathologically, the tumor was diagnosed as follicular thyroid carcinoma with capsular invasion. This is an exceptionally rare case.

We performed salvage surgery after chemoradiotherapy(CRT) in a patient with thymic basaloid cell carcinoma. A 46-year-old man with an abnormal chest shadow on X-ray findings was referred to our hospital. Computed tomography revealed a partially solid tumor along with a multilocular cyst in the anterior mediastinum with mediastinal lymph node swelling infiltrating to the superior vena cava(SVC). Positron emission tomography revealed FDG accumulation (SUVmax 7.94)in the tumor. Pathological findings of a tumor biopsy specimen obtained by thoracoscopy led to a diagnosis of thymic basaloid cell carcinoma...
