BACKGROUND Accurate tests to diagnose adenocarcinoma and high-grade dysplasia among mucinous pancreatic cysts are clinically needed. This study evaluated the diagnostic utility of amphiregulin (AREG) as a pancreatic cyst fluid biomarker to differentiate non-mucinous, benign mucinous, and malignant mucinous cysts. METHODS A single-center retrospective study to evaluate AREG levels in pancreati...
We describe a case of pseudomyxoma peritonei (PMP) successfully managed with intraperitoneal hyperthermic chemoperfusion. This case is unique due to the concurrent presence of intraductal papillary mucinous neoplasm (IPMN) of the pancreas. The patient presented with abdominal fullness. Abdominal computed tomography revealed massive ascites, thickened peritoneum, and a cystic lesion of the pancr...
The PathfinderTG biomarker panel is useful in the evaluation of pancreatic cysts that have clinical features suspicious for malignancy, but its utility in classifying fine-needle aspiration biopsies from small pancreatic cystic lesions is yet to be proven. We used morphology to classify 20 pancreatic cyst cytology aspirates, all of which met radiographic criteria for close observation. Cases we...
In cancer cells the expression of mucins is variable in amount and cellular localization. Alteration in glycosylation occurs and leads to the appearance of novel structures. The aim of this study was to investigate the expression of epitopes known as CA19-9, CA50, CA242, MUC1, MUC1-Core and Thomsen-Friedenreich (TF) in mucinous carcinomas. The formalin-fixed and paraffin-embedded tissue samples...
CONTEXT With patients surviving longer after pancreatic resection, the challenges now is the management of the unresolved longer-term issues. CASE REPORT A 53-year-old woman with painless obstructive jaundice, underwent a pylorous preserving pancreaticoduodenectomy for a pT3N0M0 ampullary adenocarcinoma in 2001 (patchy chronic pancreatitis with mucinous metaplasia of background pancreatic duc...
PURPOSE Management guidelines for pancreatic intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms (MCN) are based on the assumption that mucinous cysts can be accurately distinguished from other pancreatic cystic lesions. Previous studies using surgical material have identified recurrent mutations in GNAS and KRAS in pancreatic mucinous neoplasms. Yet, the diagnostic ut...
INTRODUCTION Report of a rare presentation of mucinous cystadenoma of the vermiform appendix. CLINICAL PICTURE A lady who presented with intestinal obstruction and peritonitis was found to have gangrenous small bowel caused by strangulation by a tumour of the appendix. TREATMENT Right hemicolectomy. OUTCOME The histology of the appendicular tumour was mucinous cystadenoma. The patient rec...
Widespread use of cross-sectional imaging and increasing age of the general population has increased the number of detected pancreatic cystic lesions. However, several pathological entities with a variety in malignant potential have to be discriminated to allow clinical decision making. Discrimination between mucinous pancreatic cystic neoplasms (PCNs) and nonmucinous pancreatic lesions is the ...
UNLABELLED Mucinous cystadenomas are relatively uncommon benign cystic tumors. Most of them are found in the ovary, pancreas, and appendix. Primary mucinous cystadenoma of spleen is extremely rare and only countable cases have been recorded. These are assumed to arise from heterotopic pancreatic tissue or invaginated spleenic capsular mesothelium. We present a rare case of primary mucinous cyst...
BACKGROUND Mucocele of the appendix is a rare condition, the pathological classification and management strategy of which have not been standardized yet. AIM To report on our management of appendiceal mucocele, highlighting the pitfalls and possible means for avoiding them. MATERIALS AND METHODS Our registries were reviewed to retrieve cases of appendiceal mucocele, encountered in the perio...
