Background: To identify the frequency and types of gastrointestinal polyps in Duhok central and private laboratories.

Methods: Gastrointestinal polyp cases received in Duhok central and private laboratories during 11-year period (from 2010 to 2020) were studied, both clinically and pathologically.

Results: A total of 689 (372 non neoplastic and 317 neoplastic) gastrointestinal polyps were reported. Hyperplastic polyps (38.71%) formed the commonest morphologic non neoplastic category followed by fibroepithelial polyps (24.46%), juvenile/retention polyps (20.43%), inflammatory polyps (14.78%), hamartomatous polyps (1.08%) and lastly fundic gland polyps (0.54%). On the other hand, tubular adenoma (93.06%) formed the commonest neoplastic: cases, followed by tubulovillous adenoma (5.36%) with a remaining 1.58% villous adenoma. Both non neoplastic and neoplastic polyps were presented predominantly in the large intestine. Only 7% of neoplastic polyps were found to be associated with adenocarcinoma.

Conclusion: Hyperplastic polyps and tubular adenoma formed the most common non-neoplastic and neoplastic polyps, respectively. The large intestine was the most dominant location. Associated colorectal cancer cases were exclusively associated with the neoplastic polyps.
