Abstract

Gastrointestinal stromal tumor (GIST) is defined as mesenchymal tumors of the gastrointestinal tract expressing proto-oncogene protein CD117. They are the most common sarcomatous tumors of the gastrointestinal tract. GISTs are presumed to arise from interstitial cells of Cajal or gastrointestinal pacemaker cells which control gut motility. They have unpredictable biological behavior. Prognosis is dependent on tumor size as well as mitotic count. Radical surgical excision is the treatment of choice. They rarely metastasize to lymph nodes. Imatinib therapy is used as an adjuvant therapy. The follow-up of patients postsurgery is not standardized.

Keywords: CD117; CD34; PDGFRA; gastrointestinal stromal tumors; gastrointestinal tumor; imatinib; jejunal tumor.

Photomicrograph showing spindle cells arranged in fascicles and interlacing bundles. Cells had oval to elongated vesicular to hyperchromatic nucleus with inconspicuous nucleoli and cytoplasm in moderate amount. Occasional mitosis, thin walled blood vessels. Interspersed in between the lesion cells are foci of hemorrhage and fibrin deposition.
