INTRODUCTION: Gastrointestinal Stromal Tumors (GIST) are lesions which origin from Intersticial Cells of Cajal that may be asymptomatic or cause complications like digestive bleeding or malignant transformation. AIM: To determine the clinical, endoscopic and histological profile, as well as the main demographic features of patients with GIST in Hospital Edgardo Rebagliati (Lima-Perú) from January 2002 to December 2004. METHODS: Descriptive, transversal and retrospective study in which we reviewed clinical and anatomopathological archives from 34 patients with GIST during the above mentioned period. The collected data were placed on a sheet of recollection. RESULTS: There was male predominance (58.82%).The most affected age group was 71-80 years old (26.47%). The average age was 64.7 years old. The most frequent clinical presentation was abdominal pain (47.06%) followed by melena (44.12%). Diagnosis was made by endoscopic method in 58.82%. The main histological type was spindle (47.06%). There was high risk of malignancy in 50% and the most often involved site was stomach (61.77%). Endoscopicall the characteristic image was a submucosal tumor with ulceration, the average size was 6.44 cm. There was significant statistical relation (p< 0.05) between endoscopic method and melena. CONCLUSION: Patients with GIST in HNERM are mostly men, older than 60 years that come with abdominal pain and melena, being endoscopy the best method to diagnose if patients present melena. Predominating histology was fusiform.
