Primary Cardiac Myxofibrosarcoma: A Case Report

Takuya Matsushiro, et al.

INTRODUCTION: Primary cardiac tumors are rare, with malignant myxofibrosarcoma cases being particularly uncommon, while cardiac myxoma is a common diagnosis in clinical practice. We present a case of cardiac myxofibrosarcoma, whose clinical course was quite unusual.

Postoperative Intra-Pouch Mucosal Bridge Formation in a Child with Ulcerative Colitis

Yuhki Koike, et al.

INTRODUCTION: Restorative proctocolectomy with construction of an ileal J-pouch anal anastomosis is an established gold standard procedure for managing ulcerative colitis. One of the reported complications is a residual mucosal bridge as a result of leaving an apical bridge remnant when constructing the ileal J-pouch. However, now that the surgical procedure is well established, such complications rarely occur.

Navigating the Challenges of Persistent Left Superior Vena Cava in the Catheterization of Peripherally Inserted Central Catheter Port: A Case Study

Takeshi Nakayama, et al.

INTRODUCTION: Persistent left superior vena cava (PLSVC), which is asymptomatic and occurs in 0.3%–0.5% of the general population, is typically detected incidentally but can complicate cardiac procedures owing to its potential to cause arrhythmias. This condition involves an additional venous return pathway to the right atrium, which can alter the cardiac anatomy and is associated with other cardiac aortic anomalies.

Benign Cystic Mesothelioma of the Peritoneum Arising at the Greater Omentum in a 14-Year-Old Boy

Yutaka Hirayama, et al.

INTRODUCTION: Mesothelioma arises from mesothelial cells. This tumor is very rare among pediatric abdominal neoplasms. We herein report an extremely rare case of acute abdomen with cystic mesothelioma of the peritoneum in a child.

Laparoscopic Intra-Mediastinum Omental Filling Repair for Spontaneous Esophageal Rupture: A Case Report

Demba Ishimine, et al.

INTRODUCTION: Spontaneous esophageal rupture is a rare but life-threatening condition with a high mortality rate. While conservative and endoscopic therapies have been reported, surgical treatment remains essential. The optimal approach involves esophageal defect repair and mediastinal drainage, which is performed via laparotomy, thoracotomy, laparoscopy, or a combination of these techniques. We report a case of laparoscopic intramediastinal omental filling for a spontaneous esophageal rupture that was challenging to close.

Cholangiolocarcinoma with Ductal Plate Malformation Pattern: A 6-Year Follow-Up

Yuta Ushida, et al.

INTRODUCTION: Cholangiolocarcinoma (CLC) with ductal plate malformation (DPM) is a rare primary liver cancer originating from the canals of Hering. It often exhibits intermediate behavior between hepatocellular carcinoma and intrahepatic cholangiocarcinoma. Diagnosing CLC with DPM is challenging due to overlapping imaging features with other liver malignancies.
