The clinical and histopathological presentations of patients with gastrointestinal stromal tumors

Objectives: Gastrointestinal stromal tumors (GIST) are originated from mesenchymal / stromal cells and are rarely seen in gastrointestinal tract. In this study, we aimed to determine the clinical and histopathological presentations, and tumor localizations of the patients with GIST.Materials and methods: Totally, 18 patients were included in the study. Ten patients were male (56%), and the mean age was 54.2 (30-75) years.Results: The most common sites of organs involved are stomach, peritonea, colon, small intestine, omentum and esophagus, respectively. The major symptom of the patients with GIST is abdominal pain. Distant organ metastasis was detected in 22.2% of the patients.Conclusion: We found that the most common presentation of patients with GIST is abdominal pain, and the most common involved organ is the stomach.
