Filiform polyposis presenting with rapid growth and severe anemia case report.

INTRODUCTION

Giant inflammatory polyposis (GIP) is a rare manifestation of inflammatory bowel disease (IBD), and it is described as a worm-like projection of 1.5 cm or more in diameter with unclear pathogenesis. GIP may be related to the severity of IBD. GIP presents with a wide range of symptoms, including crampy abdominal pain, anemia, and intestinal obstruction. The histopathology of GIP is a polyp lined by normal colonic mucosa with superficial ulceration that may show mild crypt distortion.

CASE REPORT

Our case reports a patient with ulcerative colitis diagnosed via colonoscopy and histopathology 10 months before presenting with severe anemia due to lower gastrointestinal bleeding. Colonoscopy showed GIP obstructing the descending and sigmoid colon, and total colectomy showed the entire colon full of worm-like polyps up to 14 cm the longest polyp.

DISCUSSION

Giant inflammatory polyposis which is seen in 17 % of UC with active colitis, as seen in our patient, the histopathology component was acute in addition to chronic, which formed within 6 months. According to the data in the literature, the average duration reported for formation since diagnosis with UC is approximately 3 to 276 months. With a length up to 16 cm, the sigmoid colon is the most common site.

CONCLUSION

Surgical intervention is indicated for filiform polyposis (FP) if it is complicated, such as bleeding or obstruction, which is reported in a few cases. However, there are no clear guidelines for surgical intervention for complicated FP, but the safest method is to tailor the management according to the guidelines for each underlying disease.
