Well-differentiated neuroendocrine tumor of the duodenum

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!

Theirchildren naturally are,as a rule, weakly andlack resisting power,and, for this reason,more likely to developthe disease, if the germsor seed find their wayinto their bodies.A new-born baby may have a mother, who has advan-ced tuberculosis, or be in the1 last stages of the disease, butthe lungs x>r other tissues of thebaby, when born, are always freefrom the germs of the disease.Unfortunately, most mothers donot know how to prevent thespread of this disease and thebaby often becomes infected inthe early days of its life. How the Disease Spreads. Thegerms of consumption are oftendestroyed by white blood cellsin the lungs. The attacking germsattempt to grow in the warm,moist, dark lungs, which furnishthem plenty of food. At once the alarm is given and na-ture sends out her army of policemen, the white

These infected spots become large enough to be seenwith the naked eye and the fight continues or stops depend-ing on the strength ofthe opposing sides. Often these spots,or infected areas, be-come as large as amarble, a plum, or anapple and the whiteblood cells succeed inlimiting the spread ofthe destruction bybuilding a wall orsac all around the in-vading germs and thetissue which has been destroyed.
