Perforated GIST in Jejunum - A Rare Cause of Abdominal Cocoon.

Gastrointestinal stromal tumours [GISTs] are rare but they commonly arise in stomach, and small or large intestines. They are usually accompanied with gastrointestinal bleeding. We are reporting a case of GIST which occurred in a 52-year-old male,who presented with acute abdomen. On laparotomy, the entire segment of jejunum was found to be partially encased in fibrocollagenous tissue, which formed a cocoon. Moreover, the intestine showed diffuse thickening with multiple tumour masses, which is an uncommon gross finding in GIST. This case report highlights variable clinical and morphological manifestations of GIST. Awareness on its rare clinical manifestations, including abdominal cocoon, may help in making an early diagnosis and providing timely appropriate treatment.
