Duodenal Rare Neuroendocrine Tumor: Clinicopathological Characteristics of Patients with Gangliocytic Paraganglioma

Figure 2

In the present literature survey, gastrointestinal bleeding was the most common symptom of gangliocytic paraganglioma (GP; 40.9%, 94/230), followed by abdominal pain (40.0%, 92/230), anemia (17.0%, 39/230), incidental findings (9.6%, 22/230), nausea (6.1%, 14/230), weight loss (4.8%, 11/230), and jaundice (4.4%, 10/230). It has been largely accepted that gastrointestinal bleeding and abdominal pain commonly occur in patients with GP; however, our survey revealed that obstructive jaundice is less common in patients with GP, although GP commonly occurs in the second part of the duodenum.
