[Malignant fibrous histiocytoma of the mesentery. Echographic and x-ray computed tomographic aspects. Apropos of a case]. / Histiocytome fibreux malin du mésentère. Aspects échographiques et scanographiques. A propos d'un cas.

We report one case of mesenteric malignant fibrous histiocytoma, demonstrated by pain, abdominal mass and hypoglycaemic faintness. Ultrasound showed an heterogeneous mass, with liquid areas surrounded with echogenic trabeculations. A percutaneous aspiration under ultrasound guidance of the liquid collections demonstrated sero-sanguineous material. A computed tomography showed the mass to involve the upper small bowel mesentery; organic hypoglycaemic series suggested a mesenchymal tumor, the histologic type of which was only known by post-mortem examination of the specimen.

[Myoid tumors of the stomach. Diagnostic contribution of ultrasound and x-ray computed tomography. Apropos of a case]. / Les tumeurs myoïdes de l'estomac. Apport diagnostique de l'échographie et de la tomodensitométrie. A propos d'un cas.

The authors report a new case of myoid tumour of the stomach, a chance discovery in an asymptomatic patient. The diagnosis of a heterogeneous tumour of gastric origin was made possible by echography and tomodensitometry. The myoid nature of the tumour was confirmed histologically. With the recognition of this new case the literature on the subject was reviewed. The features special to these tumours are studied with emphasis on the usefulness of echography and tomodensitometry in diagnosis, also the therapeutic approach to be adopted with regard to these tumours.
