Synchronous Gastrointestinal Stromal Tumors: A Rare Case Report.

ABSTRACT

Gastrointestinal stromal tumors (GISTs) are a subset of GI mesenchymal tumors showing neural, smooth muscle, epitheloid types of varying differentiation accounting for approximately 80% of GI mesenchymal tumors. Over 90% of GISTs occur in adults over 40 years, the most common location being stomach (50-60%) and small intestine (30-40%). We report a case of a 70-year-old man who presented with diffuse dull pain in the abdomen, a gradual loss of appetite and weight since last eight months. He was investigated and a diagnosis suggestive of GI stromal tumor-NOS type with synchronous multicentric origin having an indeterminate malignant potential was made.
