Intestinal Obstruction due to Synchronous Jejunal Stromal Tumor and Adenocarcinoma of the Colon: A Case Report

Gastrointestinal stromal tumor is the most common mesenchymal tumor of the gastrointestinal tract, and surgery is the main treatment. Synchronous tumors of the small and large bowels are rare. We report a case with synchronous jejunal stromal tumor and adenocarcinoma of the colon. A 60-years-old male patient presented with intestinal obstruction and a palpable mass located at the right lower quadrant. He underwent surgery with partial resection of the jejunum and left hemicolectomy. Histological examination revealed a high malignant potential gastrointestinal stromal tumor in the jejunum and adenocarcinoma in the colon. Immunohistochemical stains showed positive staining with CD117, CD34 and S100. Though intestinal obstruction due to gastrointestinal stromal tumor has been reported earlier, this case represents the first case report in the English medical literature of synchronous jejunal stromal tumor and adenocarcinoma of the colon presenting with intestinal obstruction.
