Inflammatory fibroid polyp (Vanek's tumour): my worst nightmare in the emergency department

Inflammatory Fibroid Polyp of the Gastrointestinal Tract: A Systematic Review for a Benign Tumor

BACKGROUND/AIM

Inflammatory fibroid polyp (IFP) is a rare, usually solitary and intraluminal polypoid benign tumor that can affect any part of the gastrointestinal (GI) tract, although in the majority of cases it affects the stomach. This lesion is characterized by proliferation of highly vascular fibrous tissue and infiltration by a variable number of different inflammatory cells. Its etiology is unknown. Our aim was to describe all the reported data concerning IFP.

MATERIALS AND METHODS

An extensive search of the PubMed Index was performed for publications with titles or abstracts containing the terms: "inflammatory fibroid polyp" with/without "Vanek". Results were filtered for publications in English and concerning only humans. One hundred and twenty-four publications were finally included in this review.

RESULTS

IFP has a female predominance. It affects patients in their 5th decade of life, although there are cases of patients from 4 to 84 years of age. IFP usually affects the stomach and more specifically the gastric antrum but can be detected throughout the GI tract. A significant number of cases remain asymptomatic but the most frequent presentations of IFP are abdominal pain, acute abdomen and GI bleeding. Most cases are treated by endoscopic resection of the lesion. No recurrence nor IFP-specific complications have been reported. Histopathology of IFP varies.

CONCLUSION

It is relatively safe to conclude that both the etiology and the timing of diagnosis might change the histopathology, immunohistological staining and tissue structure of IFP. Suggested theories should be taken into consideration with caution as the etiology and pathophysiological mechanisms of IFP are unknown.

Bowel intussusception in adults: a report of three interesting cases and current trends for diagnosis and surgical management

BACKGROUND

Bowel intussusception in adults remains a rare and constant diagnostic challenge for surgeons. It has an incidence of around 2-3 new cases per million per year, and its primary cause is benign or malignant neoplasms of the small bowel and colon. This report aims to outline the importance of high clinical suspicion regarding intussusception in adults presenting with abdominal pain in the emergency department.  Case report: This is a retrospective review of three cases of adult ileocecal intussusception that were treated in a single surgical department in three years (2015-2018). All patients underwent right hemicolectomy in keeping with the principles of surgical oncology. Each patient had a different clinical presentation, while, in terms of the underlining pathology, the first had an adenocarcinoma of the ascending colon, the second an adenocarcinoma of the ileocecal valve, and the third one an inflammatory fibroid polyp of the ileocecal valve, also known as Vanek's tumor.

CONCLUSION

Large bowel intussusception in adults is quite an interesting entity, not only for its rarity but for its non-specific and atypical clinical presentation as well. High suspicion from the clinician's part and availability of a computed tomography scan is the key to diagnosis. It is not unusual for imaging modalities to be unable to identify the cause of the intussusception. Thus, surgery is always the preferred method of treatment, as, more often than not, a neoplasm of the small or the large bowel is the underlining pathology.  HIPPOKRATIA 2019, 23(1): 37-41.

Inflammatory fibroid polyps of the appendix: different presentation and literature review

Inflammatory fibroid polyps (IFPs), or Vanek’s tumor, are rare benign mesenchymal lesions of the gastrointestinal tract (GIT). IFPs can be found throughout the GIT but most frequently in gastric antrum or ileum, with the appendix accounting for only <1% of all IFPs. The clinical presentation is usually vague yet depends on the location. We report a case of 50-year-old healthy male presented to the emergency department with a sub-acute complaint of non-specific abdominal pain, which was suspected to be appendicitis. Abdominal CT scan was done as well as colonoscopy and histopathology were scheduled. A week later, he presented in the clinic, still complaining of abdominal pain; thus, the decision was made to schedule him for laparoscopy with appendectomy. Finally, the post-operative course was unremarkable and the patient was discharged home. This is a rare case of IFPs originating in the appendix presenting as an atypical sub-acute appendicitis.
