Inflammatory Fibroid Polyp or Vanek’s Tumour

Abstract

We report a case of a 65-year-old woman who presented with recurrent episodes of severe, postprandial abdominal pain followed by projectile vomiting. Gastroscopy revealed a large polyp in the prepyloric region. During peristalsis, the polyp was repeatedly ‘passing’ through the pylorus into the duodenal bulb, hence obstructing the lumen. The polyp was eventually removed in a piecemeal fashion. Histopathologic examination revealed an inflammatory fibroid polyp (known also as Vanek’s tumour). A brief review on inflammatory fibroid polyps follows.

Surgical Resection of a Rare Inflammatory Fibroid Polyp of the Stomach: A Case Review

“…The anatomic location and size of the polyp determine whether the procedure is open or endoscopic [17]. Inflammatory fibroid polyps have not been found to recur after excision, nor have additional polyps been found to develop [18].…”

Inflammatory fibroid polyp (Vanek's tumour), an unusual large polyp of the jejunum: a case report

“…When symptomatic, the clinical presentation relates to the site of the tumour. The symptoms are often vague and can include nausea, vomiting, dyspepsia, abdominal pain and change in bowel habit [3,16]. If the overlying mucosa ulcerates then GI bleeding or anaemia may occur.…”

“…When present, they are mostly found in the gastric antrum (70%) or in the ileum (20%); however, they are considered to be very rare in the duodenum and jejunum [2]. IFPs are usually found incidentally in asymptomatic patients [3]. However, patients can also present with abdominal pain, weight loss, bleeding, dyspeptic symptoms and obstruction, with the pattern of symptoms dependent on the site and size of the lesion [2].…”

Inflammatory fibroid polyp (Vanek's tumour) of the bowel

“…Whereas gastric IFP exhibits positivity only for CD 117. 9,10 It is the lower gastrointestinal IFP's which pose a diagnostic dilemma. Push and pull enteroscopy or double balloon enteroscopy can aid in the diagnosis.…”
