[Inflammatory fibroid polyp of the ileum presenting as intussusception: a case report in an adolescent]. / Polype fibro-inflammatoire de l'intestin grele revele par une invagination intestinale aigue: a propos d'un cas chez une adolescente.

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 patient who underwent emergency surgery because of acute intestinal obstruction as a result 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 etiology is unknown. We discuss the clinical, the pathological aspects and the possible etiological factors of the inflammatory fibroid polyp.

[Hepatic mesenchymal hamartoma in adulthood: a case report with literature review]. / Hamartome mesenchymateux du foie chez l'adulte: a propos d'un cas avec revue de la littérature.

Mesenchymal hamartoma is a rare and benign tumor.. Representing 5 to 8 % of children's hepatic tumors, it is rarely described in adults. Authors report a new case of hepatic mesenchymal hamartoma in a 21-year-old woman, diagnosed after a sudden onser of clinical and biological cholestasis. Abdominal US and CTscan exminations showed a medial liver tumor with cystic formations suggestive of a hydatid cyst. The diagnosis of hepatic mesenchymal hamartoma was based onn hitology of the resected liver specimen. Radiological findings can suggest the diagnosis but only histology can confirm it. Treatment is surgical involving in most of the cases; a wide hepatic resection because of the size of the tumor. Progosis is excellent when complete exeresis is possible.
