Unusual Gastrointestinal Hemorrhaging Mimicking a Rupture of Solitary Gastric Varices Due to a Gastric Gastrointestinal Stromal Tumor with Exogenous Growth

Abstract

Gastric gastrointestinal stromal tumors can lead to upper gastrointestinal hemorrhaging, which is usually caused by dimpling or ulceration on the tumor surface. While rare, pedunculated gastric gastrointestinal stromal tumors outside the stomach can present as a huge mass with delayed complaints. We herein report an unusual hemorrhaging mimicking a rupture of solitary gastric varices due to a pedunculated gastric gastrointestinal stromal tumor. In this case, contrast-enhanced computed tomography was essential for tumor detection. An endoscopic investigation revealed dilated, aberrant veins and arteries in the submucosa of this tumor, recognized as solitary gastric varices.

A Case Report of an Unusual Presentation of a Pedunculated Gastrointestinal Stromal Tumor: Acute Upper Gastrointestinal Bleeding in a 57-Year-Old Female

“…Immunobiological staining was used to differentiate between the types of GIST. In our patient, the caldesmon stain was positive, which is only observed in 10% of all the cases (Figures 5, 6,7,8). The neoplasm is positive for DOG1, Caldesmon, and CD117.…”

“…Shenoy and Singh reported a neonatal boy diagnosed with GIST in the terminal ileum after presenting with intestinal obstruction and vomiting one day after his birth [5]. To current knowledge, there is one report of solitary gastric pseudo-variceal rupture caused by pedunculated GISTs of a 64-year-old male [6]. He was admitted to the emergency department due to episodes of hematemesis and melena, and presented with normal blood pressure (120/90 mmHg) and tachycardia (102 beats/min).…”
