Introduction
Pancreatic tumors—also referred to as pancreatic neoplasms—may be benign or malignant. Benign pancreatic tumors can cause symptoms such as diarrhea, abdominal pain, and jaundice. Examples of benign pancreatic tumors include insulinomas (pancreatic islet cell tumors), neoplastic cysts, and true pancreatic cysts. Insulinomas most commonly occur in the tail and body of the pancreas; the majority are solitary, with only a small minority being multiple.
Benign pancreatic tumors include insulinomas, adenomas, lipomas, and fibromas—however, all are exceedingly rare. Insulinomas most commonly occur in the tail and body of the pancreas; the majority are solitary, with only a small minority being multiple. Below, we address the question: “What are the clinical manifestations of benign pancreatic tumors?”
Clinical Manifestations of Benign Pancreatic Tumors
“Pancreatic tumor” refers to any neoplasm arising in the pancreas. Benign pancreatic tumors may present with symptoms such as diarrhea, abdominal pain, and jaundice.
Benign pancreatic tumors include insulinomas, cystic neoplasms (cystic tumors), and true pancreatic cysts. Insulinomas predominantly arise in the pancreatic tail and body; most are solitary, with only a few cases presenting as multiple lesions. Tumor size varies, with an average diameter of approximately 1–2 cm. These tumors are slightly firm, round, and appear red or purplish-red. Histologically, they consist of tumor cells resembling normal islet cells, arranged in nests or cords separated by fibrous connective tissue. Approximately 80% of insulinomas are benign, typically encapsulated by a well-defined capsule and sharply demarcated from surrounding tissues. Cystic neoplasms account for about 10% of all pancreatic cysts. They usually develop in the pancreatic tail and possess a fibrous capsule containing mucinous material; occasionally, blood-tinged fluid may also be present. The inner lining of these cysts often exhibits papillary projections. True pancreatic cysts most commonly arise within pancreatic parenchyma; retention cysts result from obstruction of the pancreatic duct.
When a cyst compresses adjacent bowel loops, patients may experience postprandial epigastric fullness or discomfort, followed by anorexia, nausea, vomiting, diarrhea, and abdominal pain—typical gastrointestinal symptoms. Compression of the common bile duct by a cyst may lead to obstructive jaundice. Upon diagnosis of a pancreatic tumor, prompt surgical resection is strongly recommended.
The above outlines the clinical manifestations associated with benign pancreatic tumors. We hope this information is helpful to you.
