Summary
A rare leiomyoma-like clip artifact occurred after endoscopic full-thickness resection of a colon tumor. This case highlights the importance of pathologist communication regarding foreign bodies to prevent diagnostic confusion.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Endoscopic Surgery
Background:
- Endoscopic full-thickness resection (FTRD) is an effective technique for removing colorectal lesions.
- Post-resection surveillance is crucial for detecting recurrence and complications.
Observation:
- A 69-year-old man developed a polypoid lesion containing a trapped clip 12 months after FTRD for a granular laterally spreading tumor.
- Histological examination revealed a leiomyoma-like artifact composed of muscular tissue, including muscularis mucosae and muscularis propria.
Findings:
- The polypoid formation was attributed to full-thickness clip entrapment of the colon wall, leading to abnormal muscularis propria growth.
- This represents a novel finding of a clip artifact leiomyoma, previously unreported.
Implications:
- Foreign bodies like clips can cause diagnostic confusion by mimicking neoplastic or mesenchymal lesions.
- Accurate communication between endoscopists and pathologists regarding surgical techniques and foreign body presence is essential for correct diagnosis.
