[Inflammatory fibroid polyp of the ileum presenting as intussusception: a case report in an adolescent]

ABSTRACT

Inflammatory fibroid polyp is an uncommon and benign submucosal lesion of the gastrointestinal tract. The maximal incidence is in the fifth and sixth decades. The main histological characteristics are diffuse inflammatory infiltrate with eosinophils and highly vascularized fibrocystic stroma. We report a case of 15-year-old woman who underwent emergency surgery because of acute intestinal obstruction as a results of an intussusception. The macroscopical study after segmental ileal resection showed a nodular lesion 3x2x2 cm, arising from the submucosa with an ulcerated surface. The pathologic diagnosis was ileal inflammatory fibroid polyp. Immunohistochemically, the cells reacted with vimentin and CD34. It has no malignant potential although extensive infiltration may occur. The aetiology is unknown. We prepose to discuss the clinical, the pathological aspects and the possible aetiological factors of the inflammatory fibroid polyp
