Small GIST mimicking gastric erosion as a cause of mycrocytic anemia

Introduction: Gastrointestinal stromal tumors (GIST) are submucosal lesions and forceps biopsies can rarely obtain materials for histological diagnosis. Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) allows detailed imaging of intramural structures of the stomachand also allows obtaining materials for cytological analysis. Case report: A 60 year old female with history anemia underwent upper gastrointestinal endoscopy for upper abdominal pain. Endoscopy revealed hyperemic antral mucosa and one bigger erosion on the border of corpus and antrum. IPP was introduced in therapy. On repeated endoscopy, it was more clearly that erosion was on small polyp. Multiple forceps biopsies were taken from the polyp in the 2 consecutive endoscopies, but malignancy wasn't found. Endoscopic ultrasound revealed small lesion size 11x9mm in muscularis propria and no lymph nodes in the region. EUS guided FNA was performed and material was obtained for cytological analysis. Cytological finding was GIST. MSCT confirmed tumor and excluded dissemination. Patient underwent laparoscopic partial resection of stomach. Histology confirmed GIST. The surgical procedure was without complication and the patient was discharged 5 days after operation. Conclusion: EUS-FNA allows tissue sampling of submucosal lesions and early diagnosis of GIST. Since the size of a tumor is the major predictor of GIST's malignancy, resection of a small GIST is usually the only therapy.
