Summary
[edit]DescriptionWell-differentiated neuroendocrine tumor of the duodenum (3048456334).jpg |
Polypectomy from a 78-year-old man who presented with weight loss. The whole tumor is no more than 0.7 cm in greatest diameter and appears limited to the mucosa and submucosa. Histologically, the tumor is composed of bland cells arranged in predominantly a cribriform ("type C") pattern, but there are no psammoma bodies. Since the tumor is small and superficial, I expected it to be totally benign. However, I asked the clinician to check the serum levels of gastrin and somatostatin, and the gastrin level was "sky high." This finding would bump the tumor into the "low-grade malignant potential" category. If the patient has clinical Zollinger-Ellison syndrome, then he has a 30% probability of having metastases, the small size of the primary notwithstanding. Never a dull moment in surgical pathology! |
