# Postprandial abdominal pain and weight loss as the initial presentation of abdominal neuroendocrine tumor recurrence

## TL;DR

A middle-aged man experienced post-meal stomach pain and weight loss due to a rare recurrence of a neuroendocrine tumor.

## Contribution

The paper presents an atypical initial presentation of abdominal neuroendocrine tumor recurrence.

## Key findings

- Postprandial abdominal pain was an unusual symptom of tumor recurrence.
- The case highlights the diagnostic challenge of atypical neuroendocrine tumor presentations.
- A high index of suspicion is needed for rare tumor recurrence presentations.

## Abstract

Neuroendocrine tumors, rare and slow‐growing, primarily affect the gastrointestinal tract, causing symptoms due to hormone secretion or mass effect. This case image described postprandial abdominal pain as an atypical initial presentation of abdominal neuroendocrine tumor recurrence in a middle‐aged male.

Neuroendocrine tumors are a group of rare, slow‐growing neoplasms, most commonly affecting the gastrointestinal tract. Clinical presentations include symptoms related to the mass or hypersecretion of hormones, such as flushing, diarrhea, or bronchoconstriction. Postprandial abdominal pain is most commonly related to chronic mesenteric ischemia from atherosclerotic changes but is rarely linked to external mass compression, including gastrointestinal tumors. Hereby, the authors highlight an uncommon presentation of NET, which is very challenging to diagnose and demands a high index of suspicion.
