HYPOTHESIS Intraductal papillary mucinous tumors (IPMTs) of the pancreas may be meaningfully construed as representing 2 clinically distinct subtypes: main duct tumors (MDT) and branch duct tumors (BDT). DESIGN Retrospective study. SETTING University hospital from January 1988 through December 1994. PATIENTS AND INTERVENTION We reviewed diagnostic findings and late results of surgical tre...
Bloody nipple discharge is the main and in most cases only symptom of intraductal breast cancer. Detection this pathology a rather complex process involving prescription extra research methods. Ultrasound mainly used addition to such leading diagnostic methods as mammography, ductography. However, above case report, ultrasound presented an independent method.
UNLABELLED Recently, several studies of intraductal papillary neoplasms (IPN) of the biliary tracts have been reported in the liver, but there have been only one study of them in the common bile duct (CBD). The author reviewed 34 archival pathologic materials of surgically resected specimens containing CBD tumors. RESULTS Six cases (18%) of IPN of the CBD were found. All cases were non-invasi...
PURPOSE To assess the feasibility and safety of percutaneous intraductal radiofrequency ablation (RFA) for unresectable Bismuth types III and IV hilar cholangiocarcinoma. RESULTS Percutaneous intraductal RFA combined with metal stent placement was successful in all patients without any technical problems; the technical success rate was 100%. Chemotherapy was administered to two patients. Afte...
BACKGROUND The optimal course of clinical follow-up after a diagnosis of breast papillary lesion on a core needle biopsy (CNB) remains elusive. In particular, no reports in literature have addressed this question in African-American population. We describe our experience with breast papillary lesions in a primarily African-American population. METHODS A search of our database for breast papil...
Intraductal neoplasms are important precursors to invasive pancreatic cancer and provide an opportunity to detect and treat pancreatic neoplasia before an invasive carcinoma develops. The diagnostic evaluation of these lesions is challenging, as diagnostic imaging and cytological sampling do not provide accurate information on lesion classification, the grade of dysplasia or the presence of inv...
Undifferentiated carcinomas with osteoclastic giant cells of the pancreas (OGC) are rare tumors. The current impression in the literature is that they are highly aggressive tumors similar in prognosis to ductal adenocarcinomas. In this study, the clinicopathologic characteristics of 38 resected OGCs were investigated and contrasted with 725 resected pancreatic ductal adenocarcinomas without ost...
PURPOSE Among invasive ductal carcinomas of the pancreas (IDCP), there is a morphologically characteristic subgroup accompanied by abundant intraductal carcinoma components (ICCs). With the aim of determining whether ICC-rich IDCP are biologically different from ICC-poor IDCP, the expression status of Dpc4 protein was analyzed. EXPERIMENTAL DESIGN A total of 43 IDCP was subdivided into two gr...
