Abstract:
Gastrointestinal stromal tumour (GIST) is a type of tumour that occurs in gastrointestinal (GI) tract, and arises from stroma with no definite cell line of origin and varying pattern of differentiation. It is a type of soft tissue sarcomas. We report a case of a young adult female who was diagnosed with GIST which was found to be unresectable at surgery and was subsequently managed with Imatinib. Treatment with the drug has led to a significant improvement for about 2 years.
