“…It is usually associated with a history of ulcerative colitis, Crohn's disease and intestinal tuberculosis. Filiform polyposis develops as a postinflammatory reparative process in response to the altering ulceration and healing cycles during chronic luminal inflammation 1. Filiform polyposis itself is not considered precancerous and thus does not require surgical resection except in complications including bowel obstruction,2 as in this case.…”

“…To the best of our knowledge, 22 similar cases of filiform polyposis in patients without a history of inflammatory bowel disease (7 women, 15 men) have been reported at the time of writing [16]. Filiform polyposis may be sequelae of prior injury or inflammation and has been reported to be associated with necrotizing enterocolitis, enema-induced colitis, ureterosigmoidostomy, stercoral ulcer, Langerhans cell histiocytosis X, or colonic tuberculosis [11]. In contrast, some authors suggest that the pathogenesis of filiform polyps may not be related to a postinflammatory reparative process but instead to a hamartomatous process because they have recorded observations of neuromuscular and fibrovascular hyperplasia or disarray [13].…”

“…On microscopic examination, the polyps are lined by normal, edematous, or superficially ulcerated colonic mucosa [10]. Filiform polyposis usually has a thin, straight shape resembling the stalks of polyps without the heads [11]. The polyps usually range in size from 1.5 to 3.0 cm in length, but may occasionally grow up to 9 cm in length forming a giant polyp.…”

Filiform polyposis is an uncommon entity that is most often encountered in the colon of patients with a history of inflammatory bowel disease (IBD). We report a case of filiform polyposis occurring in a 71-year-old man with no history, or symptoms of IBD. The patient was found to have numerous polypoid lesions in the ascending and proximal transverse colon endoscopically and underwent hemicolectomy. Gross examination revealed numerous finger-like polyps spreading in the ascending colon and transverse colon. Histologic evaluation of the excised specimen demonstrated the polyps lined by cytologically bland colonic mucosa with fibrovascular cores. Acute and chronic inflammation including crypt abscesses was focally present. No significant ulcerations, granulomas, dysplasia or malignancy were identified. The diagnosis was filiform polyposis and he had an uneventful postoperative course. The pathogenesis of colonic filiform polyposis is still uncertain. Filiform polyps themselves are not considered precancerous in the patients without IBD.

“…Even though the pathogenesis of FP is uncertain it is generally thought to be associated with postinflammatory reparative process [2]. The term FP was introduced by Appelman et al who used it to describe a syndrome involving the radiological appearance of numerous long slender worm-like or filiform defects in the colon [3].…”

Giant filiform polyposis in a patient with inflammatory bowel disease presenting with intestinal obstruction

SummaryA 50-year-old known patient with ulcerative colitis with relapses and remissions presented with clinical features suggestive of bowel obstruction. Radiological studies confirmed an obstructive mass lesion in the hepatic flexure of the colon. Due to bowel obstruction and suspicion of malignancy an emergency laporatomy and partial ileo-colectomy was performed. A complex polypoid mass comprising numerous slender straight finger-like villi lined by non-neoplastic colonic mucosa with serrations at the base and prominent lamina proprial smooth muscle splaying was identified and a diagnosis of filiform polyposis was made. We report this unusual manifestation of an inflammatory reaction presenting as a colonic mass clinically and radiologically mimicking malignancy.
