Mesenchymal Lesions of the Gut

Polypoid mesenchymal lesions of the colon are increasingly being detected because of growth in the number of colonoscopic procedures for colorectal cancer screening.

The histological differential diagnosis of these lesions is broad and includes gastrointestinal stromal tumors (GISTs), fibrous lesions, and neoplasms of smooth muscle and neural origin.
