Gastroscopy with virtual chromoendoscopy

Presentation of the case of a 47-year-old patient who had been complaining about abdominal symptoms with concomitant diarrhea for years. An external gastroscopy showed a small post-bulbar mass that was histologically consistent with a well-differentiated neuroendocrine tumor.
Here, the gastroscopic visualization of the finding obtained using virtual chromoendoscopy is presented.

Take home messages:

Given the family history and multiple endocrine tumors in the duodenum, the natural conclusion is to suspect a late manifestation of MEN 1.

Further diagnostics should focus on gastrin levels and sonographic studies of the thyroid and pancreas.
