BACKGROUND: Giant fibrovascular esophageal polyps are rare benign intraluminal tumors that originate from the submucosa of the cervical esophagus [Owens et al. (JAMA 103: 838-842, 1994), Totten et al. (JAMA 25:606-622, 1953)]. Due to their indolent course, these tumors tend to reach enormous proportions before patients develop symptoms. Accurately diagnosing these tumors is difficult, as endoscopy may miss 25% of these lesions because these polyps exhibit normal intact esophageal mucosa [Levine et al...

A 50-year-old man had undergone chemotherapy and radiotherapy for malignant lymphoma 1 year earlier. Follow-up computed tomography revealed a gallbladder polyp. Transabdominal ultrasound demonstrated a 20-mm hypoechoic sessile polyp with basal waist in the gallbladder fundus; the surface was covered with a hyperechoic layer of non-uniform thickness. On contrast-enhanced computed tomography, the polyp showed an early uniform and sustained staining pattern. Magnetic resonance imaging revealed that the polyp had low and slightly high signal intensities on T1- and T2-weighted imaging, respectively...

OBJECTIVE: Human submandibular gland (SMG) stones are associated with inflammation, fibrosis and microcalcifications in the surrounding tissues. However, there is little information about the accompanying cell injury-repair process, apoptosis, and cell proliferation. The purpose of this study was to investigate such an association and its clinical significance. DESIGN OF STUDY: Mid-gland paraffin sections of human SMGs ("stone glands") and normal SMGs ("non-stone glands") were subjected to stains for general histology (hematoxylin and eosin), fibrosis (Masson's trichrome), and calcification (alizarin red) and to immunohistochemistry for proliferative activity (Ki-67), and apoptosis (Caspase-3)...

AIM: Gastrointestinal stromal tumors (GIST) are quite rare tumors, but yet they are the most common mesenchymal lesions of gastrointestinal tract. Their outmost frequent origin site is stomach and presently surgical resection is the mainstay in the treatment of gastric non metastatic GIST. Their peculiar characteristic of growth and poor metastatic tendency make this tumors particularly prone to be managed by minimally invasive technique. Presenting our experience we want show the feasibility and safeness of laparoscopic approach for gastric GIST and its benefits versus traditional open surgery and pointing out short term and long terms outcomes...

Intracranial aneurysms are heterogeneous in histopathology and imaging appearance. The biological behavior of different types of aneurysms is now known to depend on the structure and physiology of the aneurysm wall itself in addition to intraluminal flow and other luminal features. Aneurysm wall structure and imaging markers of physiology such as aneurysm wall enhancement have been assessed in many prior investigations using conventional-resolution MRI. Recently, high-resolution vessel wall imaging (HR-VWI) techniques with MRI have been introduced...
