A case of giant upper abdominal mass

Abstract

Gastrointestinal stromal tumours (GISTs) are  defined as gastrointestinal mesenchymal tumours expressing a protooncogene protein called CD117 detected by                    immunohistochemistry. GISTs are rare and constitute              about 1-3 percent of all gastrointestinal (GI) malignancies, nevertheless they are the commonest type of GI                        mesenchymal tumours. We present a case of huge upper abdominal mass which radiologically showed an exophytic mass arsing from the left lobe of liver and spleen and was preoperatively diagnosed as a case of Hepatocellular                   carcinoma of left lobe of liver and Splenic hemangioma .  Peroperatively we found a mass arising from stomach        extending upto and adherent to splenic hilum and left dome of diaphragm, and we proceeded to do sleeve gastrectomy with enbloc resection of tumour and splenectomy. HPE report came as Malignant GASTRO INTESTINAL STROMAL         tumour. Postoperative period was uneventful and patient was discharged. Surgery is the definitve cure for GIST. IMATINIB is now consider as drug of choice for metastatic and              inoperable GIST
