Résumé

Les tumeurs myofibroblastiques inflammatoires (TMI) sont des tumeurs de classe intermédiaire. Elles sont rares et d’étiologie inconnue. Décrites initialement au niveau des poumons, elles ont été observées dans plusieurs autres localisations, essentiellement abdominales et pelviennes. Sa localisation au niveau de l’estomac est extrêmement rare. Nous rapportons l’observation d’une patiente âgée de 52 ans, qui présentait une tumeur gastrique de localisation extraluminale associée à une sensibilité épigastrique sans masse palpable. L’échographie et le scanner abdominal ont mis en évidence une masse de 7 cm siégeant entre le foie et l’estomac. Après l’exérèse chirurgicale de cette masse, l’examen histologique et immunohistochimique était en faveur d’une TMI gastrique. Les caractéristiques cliniques et histologiques de cette entité anatomoclinique seront discutées à la lumière des données de la littérature.

Abstract

Inflammatory myofibroblastic tumor (IMT) is a clinical and pathological disease entity, which is an inflammatory lesion with unknown etiology and is classified as intermediate neoplasm in theWorld Health Organization histological typing. It usually originates from the lung, but can also arise in any sites in the body. IMT of the stomach in adults is extremely rare, with unpredictable prognosis. We present a 52-year-old woman with exophytic tumor of the stomach. Physical examination showed mild abdominal tenderness in the hypogastrium, but no palpable abdominal mass. Abdominal CT scan showed a mass of approximately 7 cm, between stomach and liver. The final diagnosis was consistent with the IMT that originated from the gastric wall. The clinical and histopathological features of this rare lesion are described with a review of the previously reported cases.
