Surgical resection of a giant pericardial cyst: a case report.

Background: Pericardial cysts are rare congenital mediastinal cysts. They are typically asymptomatic and are often discovered incidentally, although some patients may present with chest pain and dyspnoea. Asymptomatic patients are managed conservatively with multiple modalities, with surgical resection often recommended for symptomatic patients only.

Rupture of a huge infectious abdominal chronic expanding hematoma.

A 72-year-old woman was referred to our hospital with the diagnosis of peritonitis due to the rupture of a huge abdominal cystic tumor, 27 cm in diameter. Abdominal computed tomography 14 years before revealed the tumor, which was 18 cm in diameter. She had undergone no examinations or treatment in the interim.

Conversion surgery for initially unresectable pancreatic ductal adenocarcinoma with synchronous liver metastasis after treatment with FOLFIRINOX.

FOLFIRINOX is a highly effective anticancer treatment, even in advanced pancreatic cancer, which provides a potential cure in patients initially treated with a palliative strategy. A 47-year-old man was found to have an unresectable pancreatic cancer (4 cm in size) surrounding both the superior mesenteric artery and superior mesenteric vein. A simultaneous liver metastasis in Segment 8, with a diameter of 17 mm, was also detected.

An autopsy case of aortic root rupture with thin porcelain aorta during balloon-expandable transcatheter aortic valve implantation.

A 92-year-old woman was transferred to our institute due to drug-resistant heart failure from severe aortic stenosis. She seemed to be a candidate for transcatheter aortic valve implantation (TAVI) because of her frailty and porcelain aorta. There were no severe calcified nodules in the left-ventricular outflow tract area.

Clinicopathologic Diversity of Undifferentiated Sarcoma With BCOR-CCNB3 Fusion: Analysis of 11 Cases With a Reappraisal of the Utility of Immunohistochemistry for BCOR and CCNB3.

Undifferentiated sarcoma harboring the BCOR-CCNB3 fusion is characterized by its predilection to affect skeletons of adolescent males, cellular small round/spindle cell morphology, and CCNB3 immunoreactivity. We analyzed 11 cases of BCOR-CCNB3 sarcoma, 10 of which were identified in a reverse transcription-polymerase chain reaction-based screen of 85 patient samples recorded in our database as unclassified small round or spindle cell sarcomas. BCOR rearrangements were confirmed by fluorescence in situ hybridization in 8 tumors.

Repeated recurrence of a gastric gastrointestinal stromal tumor on the chest wall after initial curative resection: Report of a case.

Introduction: Extra-abdominal recurrence or metastasis of a gastrointestinal stromal tumor (GIST) is very rare. Chest wall recurrence of a resected gastric GIST is extremely rare.

Presentation Of Case: A 64-year-old Japanese man had undergone proximal gastrectomy for a gastric submucosal tumor 11 years previously.

Resting angina due to papillary fibroelastoma of the right coronary cusp.

A 63-year-old man with chest pain at rest was referred to our hospital. Transthoracic echocardiography showed a mobile ball-like mass at the top of the right coronary cusp. Subsequently, transesophageal echocardiography also showed a mobile mass at the right coronary cusp.

Inadvertent coronary endarterectomy during aspiration thrombectomy with a Thrombuster III GR catheter in a patient with acute coronary syndrome.

We describe a 41-year-old woman who presented with acute ST-segment elevation myocardial infarction. Emergent percutaneous intervention was performed with aspiration thrombectomy followed by coronary artery stenting. White material was extracted from the aspiration catheter.

An autopsy case of the rupture of a giant aneurysm in a saphenous vein graft: 18 years after CABG.

The saphenous vein is a widely used blood vessel for arterial bypass procedures. Failures of saphenous vein aortocoronary bypass grafts are predominantly the result of subsequent vein graft atherosclerotic disease. Rarely saphenous vein grafts undergo aneurysmal degeneration.

Free-floating thrombus in the right common carotid artery.

We report the case with type A acute aortic dissection that vascular echo disclosed a free-floating thrombus in the right common carotid artery.

[A patient with an angiomyolipoma of the liver in whom the course of enlargement could be confirmed].

The patients was a 54-year-old woman. In the liver, a high-echo phyma was detected. The lesion increased from 5 to 23mm over 2 years and 4 months.

Radical excision of thymic adenocarcinoma with selective cerebral perfusion.

Most cases of thymic carcinoma have some invasion to neighboring organs when diagnosed, and it is generally difficult to completely remove. We adopted selective cerebral perfusion as a cerebral protection and successfully performed resection of a thymic adenocarcinoma that involved the superior vena cava, left brachiocephalic vein, right brachiocephalic artery and vein, and left common carotid artery in a 47-year-old woman. Even if multiple great vessels were involved by mediastinal malignant tumor, complete resection with selective cerebral perfusion could be safely performed.

Malignant fibrous histiocytoma arising from the aortic wall mimicking a pseudoaneurysm with ulceration.

Malignant fibrous histiocytoma of the thoracic aorta associated with ulcer-like projection has not been reported previously. The hypovascular tumor of the thoracic aorta involved the mural layer, which showed intra- and extra-mural growth patterns and no significant filling defect within the aortic lumen, and mimicked ulcer-like projection with secondary pseudoaneurysm formation. Aortic tumor, although rare, should be included among the causes of an ulcer-like projection.

A novel bacterium Achromobacter xylosoxidans as a cause of liver abscess: three case reports.

Achromobacter xylosoxidans is a microorganism that may cause opportunistic infections. We detected A. xylosoxidans in three of 46 patients with liver abscess.
