Solitary fibrous tumor (SFT) mostly originates from the pleura because of proliferation of fibroblast cells. It is extremely rare for the tumor to originate from the spinal cord. Here, we report a rare case of SFT in the spinal cord that recurred repeatedly and progressed from intramedullary to extramedullary. A 40-year-old man underwent C4-5 intramedullary and extramedullary tumor resection in...

PURPOSE To investigate the associated risk factors and the prognostic impact of positive resection margins after endoscopic submucosal dissection (ESD) of early-stage gastric cancer. METHODS A retrospective analysis of prospectively collected data was performed on 319 consecutive lesions in 316 patients who underwent ESD. Age, gender, surgeons, lesion location, maximum diameter of resected sp...

BACKGROUND Angiogenesis plays a pivotal role in malignant tumor progression. The count of blood microvessels of the tumor has been recognized as an indicator of malignant potential of the tumors and provides the ability to predict tumors recurrence. The role endoglin in the Dukes B rectal cancer is still unexplored. The aims of this study were to examine immunohistochemical expression of endogl...

INTRODUCTION Primary adenocarcinomas resembling submucosal tumors are rare in the gastrointestinal tract. Almost all the submucosal tumor-like adenocarcinomas previously reported invaded the submucosa or deeper. Therefore, submucosal tumor-like lesions are usually treated by surgical resection, and those that arise in the duodenum have been treated by pancreaticoduodenectomy. CASE PRESENTATIO...

SUMMARY BACKGROUND DATA Some previous studies demonstrated better survival after transplantation for small hepatocellular carcinoma (HCC) compared with resection, but the influence of differences in tumor invasiveness between transplanted and resected patients has not been studied. This study compared the tumor characteristics of patients with HCC within the Milan criteria treated by resection ...

Background: Skull base chordoma is a rare tumor with slow and progressive growth. Significance of this tumor is it’s difficult to access location in skull base. This is the reason for various proposed techniques for resection of the tumor. Endoscopic endonasal technique is a minimally invasive approach that gives surgeons opportunity of total resection of tumor and low morbidity. Total resectio...

conclusions the patient underwent surgery several days later with complete resection of the tumor and coronary stent retrieval but his left ventricular ejection fraction remained poor after several months and he was referred for cardiac transplantation. introduction cardiac inflammatory myofibroblastic tumor is a rare tumor that can cause potentially fatal outcomes. case presentation we describ...

Biopsy of rectal carcinoid tumor is commonly taken before endoscopic resection. However the preceding biopsy can inhibit complete resection by causing blurred tumor border and fibrosis of the tissue. The objective of the study was to investigate the effect of preceding biopsy on complete endoscopic resection in rectal carcinoid tumor. It was also determined if rectal carcinoid tumors can be mac...

congenital granular cell tumor (gct) is a relatively rare intraoral benign tumor, approximately 200 cases of which have been reported in the neonatal period worldwide. the newborn infant may have feeding problems and respiratory difficulties due to airway obstruction. this lesion may be diagnosed by prenatal ultrasonography and simple resection is mostly required. we report a case of an adult t...

bronchial leiomyoma is extremely rare. to date less than 60 cases have been reported in the world literature. the presented case here is a 30 year old woman who had been treated for bronchial asthma for several years. her chest radiograph showed bulluos emphysematous changes in the right lung and computer tomography scan found the tumor in the right main bronchus near carina. diagnosis was made...
