Gastrointestinal stromal tumors (GISTs): A case report

Abstract

Gastrointestinal stromal tumors (GISTs) are rare malignant tumors, rarely found in jejunum. Diagnosis mainly relies on histopathological examination and immunohistochemistry. Management typically includes surgery and chemotherapy. Herein, we present a case of an older adult female with abdominal pain and a palpable lump and managed by small bowel resection and adjuvant imatinib therapy. The excised tumor showed positive immunoreactivity for CD117, DOG-1 and SMA. This case report highlights the importance of considering GISTs in abdominal masses and the role of CT imaging and Immunohistochemistry in diagnosis and management.
