Stromal tumors of the gastrointestinal tract are rare mesenchymal neoplasms. The majority of them are appearing in the stomach: their quite common first manifestation is bleeding. The authors report a case of polypoid gastric GIST causing severe bleeding which needed urgent surgical intervention and partial resection of the stomach. Although histological analysis of the tumor revealed low proliferation rate, the urgent operation did not result in a complete eradication of the neoplasm, thereby our patient needs further follow-up and treatment.
