Summary
A small, well-differentiated endocrine tumor in the pancreatic head mimicked a cystic tumor. This 7mm tumor caused pancreatic duct obstruction and dilatation, highlighting a rare presentation.
Area of Science:
- Gastroenterology and Hepatology
- Surgical Oncology
- Endocrinology
Background:
- Pancreatic endocrine tumors (PETs) are rare neoplasms.
- Well-differentiated tumors can present with diverse clinical manifestations.
- Cystic lesions in the pancreatic head require careful differential diagnosis.
Observation:
- A 44-year-old woman presented with a large cystic mass in the pancreatic head.
- Imaging revealed a cystic lesion, leading to initial suspicion of a cystic neoplasm.
- The patient's symptoms were related to the tumor's location and effect on the pancreatic duct.
Findings:
- Surgical resection confirmed a 7 mm well-differentiated endocrine tumor.
- The tumor was confined to the pancreatic head.
- Obstruction of the proximal pancreatic duct by the tumor caused cystic dilatation, mimicking a primary cystic tumor.
Implications:
- This case underscores the importance of considering neuroendocrine tumors in the differential diagnosis of cystic pancreatic head lesions.
- Accurate preoperative diagnosis is crucial for appropriate management of pancreatic neoplasms.
- Understanding the varied presentations of pancreatic endocrine tumors aids in clinical decision-making.

01:24Chronic Pancreatitis I: Introduction
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
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...

01:25Chronic Pancreatitis I: Introduction
Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
01:19Pancreas
The pancreas, an essential organ in the human body, is a pinkish-gray elongated structure located posterior to the stomach. It extends laterally from the duodenum towards the spleen and is firmly bound to the posterior wall of the abdominal cavity. The organ's surface has a lumpy, lobular texture that gives it a unique appearance.
The broad head of the pancreas lies within the loop formed by the duodenum, while its slender body reaches towards the spleen. The tail of the pancreas is short and...

01:16Cells and Secretions of the Pancreas
The pancreas, a vital organ within the abdominal cavity, plays dual roles in the digestive and endocrine systems, collaborating with exocrine and endocrine cells to maintain optimal digestion and blood sugar levels.
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...
