Extra luminal colonic gastrointestinal stromal tumor: a case report.
BACKGROUND
Gastrointestinal stromal tumors are the commonest mesenchymal tumors of the gastrointestinal tract, the stomach and small intestine are the favored sites of occurrence. They rarely occur in the colon, rectum and esophagus. GIST is neoplasm of mesenchymal origin originating from precursors of the interstitial cells of cajal. The symptoms of gastrointestinal stromal tumor depend on the site and size of the tumor, and may include abdominal pain, gastrointestinal bleeding or signs of obstruction; small tumors may, however, be asymptomatic. Majority of the patients with gastrointestinal stromal tumor have bloody stools and abdominal pain as the commonest manifestation. We describe a young female with extra luminal colonic gastrointestinal stromal tumor presenting as mass abdomen.


METHODS
We describe 34-year-old female from north Indian state of Jammu and Kashmir who had presented with history of slowly increasing epigastric lump associated with abdominal discomfort of 4 months duration. She had no features of luminal obstruction. Her contrast enhanced computed tomography abdomen revealed a large extra-colonic mass in relation to transverse colon. The tumor was resected and histology was suggestive of gastrointestinal stromal tumor.


CONCLUSIONS
Extra luminal colonic gastrointestinal stromal tumors are very rare and can present as mass abdomen. Resection is the treatment of choice.
