Abstract:
Case 1) A 35-year-old man was admitted to our hospital for detailed examination of a 50-mm pancreas head tumor with surrounding lymph node swelling detected on medical checkup images. Ultrasound-guided lymph node biopsy specimens gave a diagnosis of a nonfunctioning pancreatic neuroendocrine cancer, and adjuvant systemic chemotherapy was given after surgical resection of the tumor. Case 2) A 52-year-old man was admitted to our hospital for detailed examination of an 18-mm pancreas head tumor detected by medical checkup FDG-PET images. Imaging tests gave a diagnosis of a nonfunctioning pancreatic neuroendocrine tumor. He underwent surgical resection, and the tumor was diagnosed as benign pathologically. Both cases showed FDG-PET accumulation in the tumors irrespective of their malignant or benign nature. Increased prevalence of FDG-PET checkup may increase the diagnosis of pancreatic neuroendocrine tumor in asymptomatic subjects.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
Chronic Pancreatitis I: Introduction
Cells and Secretions of the Pancreas
Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices.
Concurrently, the dispersed clusters of endocrine cells throughout the...
