Interpretation of F-FDG PET/CT studies in breast is challenging owing to nonspecific FDG uptake in various benign and malignant conditions. Benign conditions include breast changes in pregnancy and lactation, gynecomastia, mastitis, fat necrosis, fibroadenoma, intraductal papilloma, and atypical ductal hyperplasia. Among malignancies, invasive ductal carcinoma and invasive lobular carcinoma are...

The appropriate management for patients with multifocal branch-duct intraductal papillary mucinous neoplasms (IPMNs) of the pancreas involving the entire pancreatic gland remains unclear. We present a 66-year-old woman who underwent pylorus-preserving pancreaticoduodenectomy for a branch-duct intraductal papillary mucinous carcinoma demonstrating a grape-like multilocular cyst, 35 mm in diamete...

Results Ductoscopy was successfully performed in 178 patients. Of these 178 patients, 34 had solitary papillomas (SP), 8 had multiple papillomas (MP), 19 had intraductal debris and 5 had ductal epithelial surface abnormality with positive cytology. Of the 34 polypoid lesions (cytology negative), 22 were excised endoscopically (endoscopic papillomectomy). Patients with MP underwent DAmicrodochec...

Chronic pancreatitis is associated with varied morphological complications, including intraductal stones, main pancreatic ductal strictures, distal biliary strictures and pseudocysts. Endoscopic therapy provides a less invasive alternative to surgery. In addition, extracorporeal shockwave lithotripsy improves the success rate of endoscopic clearance of intraductal stones. However, recent data f...

Mucinous tumors of the pancreas are rare and the diagnosis of invasive carcinoma can be a dilemma. While metastatic disease from mucinous cystadenocarcinoma (MCAC) and invasive intraductal papillary mucinous neoplasms (IPMN) have been reported, no extraperitoneal mucinous cystic metastatic disease has been described. When metastatic, the overall survival rates for invasive adenocarcinoma, mucin...

Animal models for CP in rats can be classified into 2 groups: one is noninvasive or nonsurgical models and the other is invasive or surgical models. Pancreatic injury induced by repetitive injections of supramaximal stimulatory dose of caerulein (Cn) or by intraductal infusion of sodium taurocholate (NaTc) recovered within 14 days, whereas that caused by repetitive injection of arginine or by i...

This study has analyzed the gene expression patterns of an IPMN microarray dataset including normal pancreatic ductal tissue (NT), intraductal papillary mucinous adenoma (IPMA), intraductal papillary mucinous carcinoma (IPMC), and invasive ductal carcinoma (IDC) samples. And eight clusters of differentially expressed genes (DEGs) with similar expression pattern were detected by k-means clusteri...

Ductal papillomas have unique papillary features arising from the salivary gland duct system. It comprises three rare benign adenomas, namely, inverted ductal papilloma, sialadenoma papilliferum and intraductal papilloma. Here the first case of intraductal papilloma developed in the minor salivary gland of the vestibule of the oral cavity in a 71-year-old Chinese female living in a nursing home...
