Solitary polypoid ganglioneuroma of the sigmoid colon: A rare colonic neoplasia

The authors report a case of a solitary polypoid ganglioneuroma in the sigmoid colon of a 52-year-old man, initially suspected to be a gastrointestinal stromal tumor based on imaging and biopsy results. They aim to highlight the rarity of colonic ganglioneuromas, their benign nature, and the importance of complete excision for curative treatment, while noting the potential need for follow-up imaging to monitor for recurrence.
