RESUMO
The anal fibroepithelial polyps are well-known polypoid conditions histologically consisting of connective tissue response resulting from local irritation, which is closely associated with hemorrhoids. As previously reported, the size of the polyps ranged from 3 to 19 mm, average 9 mm. A 60-year-old women was admitted complaining of anal bleeding and constipation. Colonoscopy revealed a 3.0 2.5 cm sized, subpedunculated polyp on the dendate line. We removed the polyp by per anal local excision due to its hard stalk after failure of colonoscopic removal. The histologic examination was showed mature stratified squamous epithelium with hyalinized vascular changes. We report a case of huge and hard anal fibroepithelial polyp with hemorroids misdignosed as cancer.

A giant mesenteric hemangioma with small intestinal involvement was rarely found as the cause of recurrent gastrointestinal bleeding. Enteric hemangiomas account for 7~10% of all benign tumors of the small intestine and the jejunum is the most common location. A 52-year-old man was admitted with recurrent melena for 4 years. Submucosal tumor like elevated lesion was found at just distal Ampulla of Vater. This lesion was seen woozing type bleeding. For evaluation of bleeding focus, mesenteric angiogram was done. A mesenteric angiogram revealed normal gastro-duodenal, superior and inferior mesenteric arteries. Whole abdominal computed tomography revealed low- density lesion at distal to duodenal 2nd portion. To prevent further recurrent bleeding, Whipple's operation was done. The histologic diagnosis of the lesion was a giant mesenteric hemangioma of mesentery with involvement of the mucosa of duodenum and pancreatic parenchyme.
