Diffuse filiform polyposis of the small intestine without inflammatory bowel disease.

ABSTRACT

Filiform polyposis is a rare disease, which typically occurs in patients with inflammatory bowel disease. We report a case of filiform polyposis occurring in a 56-year-old man with no history or evidence of inflammatory bowel disease. The patient's main symptoms were melena and anemia. We performed an emergency exploratory laparotomy, in which we observed worm-like polyps spread almost along the entire small intestine, and a partial resection of the small intestine to treat bleeding in the bowel was carried out. Two days later, the patient was noted to have melena again, and we performed an abdominal angiographic embolization, successfully stopping the bleeding. Histologic evaluation of the excised specimen revealed chronic inflammatory cells within the lamina propria without hyperplastic or adenomatous epithelial changes. Although the surgery was very successful, careful management of the patient was required, owing to the great risk of re-bleeding.
