Abstract
BACKGROUND
No known case of neuroendocrine tumour (NET) with schwannoma has been reported.
CASE SUMMARY
A 63-year-old female presented to our hospital with nausea and vomiting. Upper gastrointestinal endoscopy revealed a mass in the descending part of the duodenum. Using ultrasound gastroscopy, we found that the tumour originated from the submucosa and showed low echo. We removed the tumour by electrocoagulation and sent it for pathological biopsy.
CONCLUSION
Immunohistochemical results showed that the mass was a rare NET with neurilemmoma.
Core Tip: Neuroendocrine tumours (NETs) and schwannomas of the duodenum are quite rare and few clinical cases have been reported. To the best of our knowledge, this is the first publication of a NET of descending duodenum complicated with schwannoma. Through a review of relevant literature, we can deepen the understanding of this type of tumour.
