Primary Gastrointestinal Stromal Tumor Accompanied with Gastrointestinal Bleeding
Abstract
- The origin and clinical behavior of gastrointestinal stromal tumors (GISTs) have been a source of recent speculation and controversy. GIST has been applied to mesenchymal tumors that represent neither their typical leiomyomas nor schwannomas. GISTs are spindle cell tumors occurring mainly in adults with 5-year survivals in 50-56% and 10-year survivals in 35-43%. Because of its indolent and slow-growing nature, it is difficult to define it as malignancy. We report a case of benign stromal tumor of the proximal jejunum presenting melena in a 32-year-old male. Small bowel series and computed tomography of the abdomen revealed submucosal tumor in the proximal jejunum. Histological studies on the surgical resection specimen revealed a gastrointestinal stromal tumor of a benign type with no evidence of metastasis. The patient was treated with local excision of the tumor and is now in a favorable state.
