Abstract

Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal tumour of gastro-intestinal tract. Annual incidence of GIST in United States is approximately 3000-4000. Clinical presentation of GIST varies with location and size of tumour but GIST presenting with palpable abdominal mass is rare. We report a case of 38 years old male who presented with large abdominal lump. Computed tomography (CT) scan showed a large solid-cystic lesion encasing second part of duodenum and distal common bile duct. On CT differential diagnosis of Leiomyoma, Leiomyosarcoma and GIST were made. The diagnosis of GIST was confirmed by immune-histochemical study of the biopsy material. Patient underwent pancreaticodudenectomy. Post-operative course was uneventful. Patient was started on Imatinib therapy post-operatively. No recurrence noted at six months follow up.

Keywords: Gastrointestinal stromal tumours, Abdominal mass, Pancreaticoduodenectomy, Imatinib

Core tip: Gastrointestinal stromal tumours presenting with palpable abdominal mass are rare. Diagnosis is based upon histopathology and immunehistochemistry. Pre operatively patient should be evaluated with different modalities for diagnosis and resectability of tumour. Surgical resection with postoperative Imatinib chemotherapy helps to provide long term survival.
