Abstract:

Gastroenteropancreatic-Neuroendocrine Neoplasms (GEP-NEN) are a heterogeneous group of rare tumors with annual incidence of less than 5 cases per 100,000 inhabitants. GEP-NEN is often mistaken for other disorders. The primary cancer site is unknown in about 13% of patients diagnosed with GEP-NEN. We report a case of a 71-years Caucasic old man, admitted at the Internal medicine unit because of a chronic intermittent watery diarrhea. Extensive laboratory analysis, imaging and colonoscopy were not helpful to make a diagnosis. Plasma levels of chromogranin A were elevated; metanephrines, normetanephrines, urinary 5-hydroxy indolacetic acid were within the normal range. The chromogranin values prompted the suspicion of GEP-NEN, and then a 68Gallium-DOTATOC PET/CT was performed. The imaging exams showed a 9 mm-diameter nodule expressing somatostatin SSTR2-5 receptors, localized in the peripancreatic adipose tissue that we diagnosed as a GEP-NEN.
