We report a 36-year-old man with a 2-year history of central colicky abdominal pain, alternating bowel habits (predominantly constipation), intermittent rectal bleeding and bloating. Computed tomography (CT) and colonoscopy revealed a 2-cm submucosal lesion at 23\u00a0cm from the anal verge; endoscopic ultrasound showed a homogeneously hypoechoic, smooth-margined mass originating from the muscularis. The patient underwent laparoscopic anterior resection after endoscopic tattooing. Recovery was uneventful. Histopathology confirmed a 1.5-cm benign colonic schwannoma with clear margins and 17 negative lymph nodes. At follow-up he remained asymptomatic without recurrence. Colorectal schwannoma can mimic gastrointestinal stromal tumour or leiomyoma preoperatively; definitive diagnosis requires histology and immunohistochemistry (S100 positivity), and complete excision with negative margins is curative.<\/jats:p>","DOI":"10.1093\/jscr\/rjaf820","type":"journal-article","created":{"date-parts":[[2025,10,17]],"date-time":"2025-10-17T11:09:09Z","timestamp":1760699349000},"source":"Crossref","is-referenced-by-count":0,"title":["Schwannoma
