CONTEXT This report describes a minute pancreatic ductal adenocarcinoma which appeared to be in early stage tumor progression based on the study of its molecular abnormalities. In addition, it was associated with lipomatous pseudohypertrophy, a rare disease. CASE REPORT A 78-year-old male presented to our department with an incidental pancreatic tumor. Abdominal dynamic computed tomography sh...

Pancreatic ductal adenocarcinoma (PDAC) develops via an accumulation of various gene mutations. The mechanism underlying the mutations in PDAC development, however, is not fully understood. Recent insight into the close association between the mutation pattern of various cancers and specific mutagens led us to investigate the possible involvement of activation-induced cytidine deaminase (AID), ...

Pancreatic cancers are usually detected at an advanced stage and have poor prognosis. About one fifth of these arise from pancreatic cystic lesions. Yet not all lesions are precancerous, and imaging tools lack adequate accuracy for distinguishing precancerous from benign cysts. Therefore, decisions on surgical resection usually rely on endoscopic ultrasound-guided fine needle aspiration (EUS-FN...

EUS-FNA of the pancreas is the preferred method of investigating and diagnosing pancreatic masses, both solid and cystic. Most solid tumors of the pancreas are conventional pancreatic ductal adenocarcinomas (PDAC). EUS-FNA has a variable sensitivity but high specificity in the preoperative diagnosis of pancreatic lesions, although the diagnosis for well differentiated PDAC is much more challeng...

Pancreatic adenocarcinomas are highly invasive cancers for reasons that are currently unclear. Here we sought to determine if the proinvasive integrin alpha6beta4 may be related to pancreatic adenocarcinoma tumor progression. Expression of integrin alpha6beta4 was analyzed via immunohistochemistry for the beta4 subunit in normal pancreas, pancreatic intraepithelial neoplasia (PanIN) lesions, pa...

OBJECTIVE Pancreatic cystic tumors are relatively rare tumors and only 1% of them are malignant. They are often asymptomatic and detected as incidental findings through diagnostic imaging. Currently there are no universal guide lines for the correct clinical approach to pancreatic cystic lesions. Cross-sectional imaging demonstrates some typical morphological features that determine the pre-ope...

PURPOSE Characterizing the earliest chromosomal alterations of pancreatic precursor neoplasms from individuals with a familial aggregation of pancreatic cancer may provide clues as to the loci of pancreatic cancer susceptibility genes. EXPERIMENTAL DESIGN We used Illumina 370/660K SNP arrays to conduct genome-wide copy number analysis in 60 benign neoplasms [58 mostly low-grade pancreatic int...

BACKGROUND Puncture biopsy and fine needle aspiration guided by endoscopic ultrasound has been used as an effective technique and is quickly becoming the procedure of choice for diagnosis and staging in patients suspected of having pancreatic cancer. This procedure has replaced retrograde cholangiopancreatography and brush cytology due to its higher sensitivity for diagnosis, and lower risk of ...

Lymphoepithelial cysts are rare pancreatic lesions. This case report describes the first excision of such a lesion by laparoscopic distal pancreatectomy which is a recognized procedure for treatment of cystic pancreatic neoplasms. Our patient underwent complete excision of the lesion and has enjoyed complete resolution of his symptoms. Laparoscopic distal pancreatectomy may be a suitable choice...
