Calcified fibrous tumors (CFTs) are rare benign mesenchymal tumors of the gastrointestinal tract. Originally thought to be tumors of soft tissue sites, recent studies have shown the gastrointestinal tract to be the primary site of these tumors. Calcified fibrous tumors present a diagnostic challenge due to overlapping histological features with multiple stromal lesions. Understanding the core clinical, histological and immunophenotypic features of calcified fibrosarcomas is important in making an accurate diagnosis.

Endoscopic polypectomy and endoscopic mucosal resection (EMR) are the established standards of treatment for colorectal polyps. Cold snare resection is the emerging standard for the treatment of smaller polyps (<5 mm) and may also be appropriate for the removal of noncancerous polyps up to 9 mm. This approach avoids thermal injury, reduces procedure time, and may reduce the risk of late bleeding.
