A 50-year-old lady posted for surgery for a TO mass diagnosed clinically and on ultrasonography. At operation the right sided big solid and cystic mass just presented out of the surgical incision – attached to the mesentery of terminal ileum close the gut. It was excised with a small segment of ileum. Histopathology reported it to be a spindle cell gastrointestinal stromal tumor (GIST) of mesenchymal origin.
