A detailed map demonstrating the spatially restricted distribution of immune cells within the desmoplastic stroma of human pancreatic tumors opens up the field of pancreatic oncoimmunology. CD8+ T cells located in the proximity of malignant lesions are associated with a survival advantage, suggesting the existence of immunoediting. Pancreatic stellate cells appear to dictate the infiltration of...
Pancreatic pseudocysts are the most common cystic lesions of the pancreas and may complicate acute pancreatitis, chronic pancreatitis, or pancreatic trauma. While the majority of acute pseudocysts resolve spontaneously, few may require drainage. On the other hand, pancreatic cystic tumors, which usually require extirpation, may disguise as pseudocysts. Hence, the distinction between the two ent...
CONTEXT Pancreatic mesenchymal tumors are rare, accounting for only 1-2% of pancreatic tumors. A pancreatic lipoma is an especially rare condition. This is only the second report of a pancreatic lipoma diagnosed before surgery using endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA). CASE REPORT A 75-year-old woman with a round low-density lesion which had been detected by C...
BACKGROUND The diagnosis of pancreatic cystic neoplasms has become more accurate recently. In some cases, however, doubt remains regarding the lesion's malignant potential. CA 19-9 has long been identified as a reliable biomarker in differentiating pancreatic benign and malignant lesions, especially in non-jaundiced patients. CASE REPORT AND DISCUSSION We report a case of a young female who p...
CONTEXT Acinar cell carcinoma is a rare pancreatic malignant tumor, which can be associated with a particular manifestation: pancreatic panniculitis. It presents with erythematous subcutaneous nodules located mainly on the legs. The skin lesions can precede, be concurrent with or follow the pancreatic illness. The pathogenesis is not fully understood, but it is believed to be associated with hi...
We herein report a rare case of a 79-year-old man who presented with the simultaneous occurrence of pancreatic neuroendocrine tumors (PNET) and renal cell carcinomas (RCC), without any other Von Hippel-Lindau (VHL)-associated lesions or any pertinent family history. Computed tomography showed vascular-rich solid lesions in the left kidney and the pancreatic tail, measuring 72 mm and 15 mm in si...
