Acute Abdomen Syndrome Caused by a Perforated Gastrointestinal Stromal Tumor - A Case Report

Abstract

Gastrointestinal stromal tumors (GIST) are frequently observed in the stomach and intestines. Although they may be presented with various symptoms depending on their location and diameter, acute abdomen syndrome is a rare presentation form for GIST. A 54-year-old male patient was evaluated with the complaint of sudden onset abdominal pain at the urology clinic. In examination; fever (38.5 ̊C), abdominal distension and peritoneum irritation signs were detected. A mass that contained localized necrotic areas thought to have mesentery origins and intraabdominal free-fluid were detected on abdominal computed tomography. The patient was operated with the diagnosis of acute abdomen syndome. In operation; extensive intestinal content in the abdomen, a perforated tumoral mass which was 7x5 cm in diameter, and anti-mesenterically localized at the ileum segment were detected. Segmental ileum resection-end ileostomy operation was performed, and the patient was discharged as uneventful on post-operative tenth day. As a result of a histopathological analysis, a GIST (<5/50 mitotic growth) was detected. By means of this finding, we want to remind that GISTs may be presented with acute abdomen symptoms due to perforation, though rarely.
