Inflammatory fibroid polyp (IFP) is a rare benign polypoid lesion of the gastrointestinal tract. Most IFPs occur in the stomach and colonic occurrence is very rare. Histologically IFP is characterized by a mixture of numerous small vessels, fibroblasts and edematous connective tissue associated with marked inflammatory infiltration by eosinophils. We present a rare case of a pedunculated IFP in...

BACKGROUND/AIMS Benign colon (18)F-fluorodeoxyglucose (FDG) uptake is frequently observed in asymptomatic individuals. Aims of this study were to investigate the benign colon uptake by whole body FDG-positron emission tomography (PET) in asymptomatic adults and to correlate those results with colonoscopic and histologic findings. METHODS Among 3,540 subjects who had undergone FDG-PET, 43 subj...

A man with gastric cancer presented with a 3-month history of constipation and abdominal pain. Colonoscopy revealed a 9-mm pedunculated polyp in the sigmoid colon (image A), which was then removed. Histopathologic evaluation of the resected polyp (image B) revealed displaced colonic crypts with underlying proliferation of ganglion (white arrows) and spindled Schwann cells (black arrows) within ...

Robert Bagdasaryan, MD  65 year old gentleman underWent screening colonoscopy. A 5 mm polyp has been identified in the distal ascending colon and has been excised. Microscopically, spindle-shaped cells along with a collection of ganglion cells are identified in the sections taken from the polyp. Ganglioneuromas are mature, benign tumors composed of a proliferation of nerve fibers, Schwann cell...

INTRODUCTION Lipoma is a benign tumor of adipose tissue, the most common tumor of the human body soft tissues. As such, it can be found almost anywhere in the human body including the gastrointestinal system (incidence below 0.5%), but rarely in the sigmoid colon. CASE REPORT This is a case report on symptomatic polyp of the sigmoid colon, which after one year, at control colonoscopy, caused ...

single filiform polyp discovered during routine screening in an individual without symptoms or a history of colonic disease. A 47−year−old man was transferred to our outpatient department for treatment of a single colon polyp which had been inci− dentally found on medical examination. Other results including upper endoscopy and laboratory test except colonoscopy were normal. The patient was asy...

Multiple adenomatous colon polyps. An adenomatous polyp is an area where the normal cells that line the inside of the colon and begin to make mucous and form a mass on the inside of the intestinal tract. Benign (noncancerous) tumors, including: sebaceous cysts (closed sac filled with liquid found under the skin) epidermoid cysts (lumps in or under the skin often filled with liquid) fibromas (fi...

cer mortality in Taiwan, with more than 4,500 people dying of this disease in 2009. Malignant colorectal polyps represent the majority of early colorectal cancers. The term “malignant polyp” refers to a macroscopically benign appearing adenoma in which the invasive carcinoma is detected after histologic examination of the resected specimen. The muscularis mucosa must be breached to be defined a...

Lipomas of the colon are benign tumors that rarely occur. Their size ranges from 2 mm to several cm. They are usually asymptomatic but occasionally they present with clinical manifestations depending on tumor size, localization and complications, which often lead to diagnostic difficulty. A 40-year-old man presented with massive rectal haemorrhage. During colonoscopy a giant polyp of over 50 mm...

A 14 year old Malay boy with an adenocarcinoma of the transverse colon is reported. A lesion was discovered early when he presented with an uncommon complication in the form of a bowel intussusception. Emergency segmental colonic resection was performed, followed later by an extended left hemicolectomy following histological confirmation of the disease. Benign adenomatous polyp is believed to b...
