Core Tip

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.
