Early Diagnosis and Treatment of a Small Gastric Stromal Tumor – A Case Report and Literature Review

Abstract

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract and the stomach is the most affected site. Clinical manifestation is erratic depending on the tumor’s location, size, histological type, and stage. Ultrasound is useful in detecting gastric intramural tumor whereas computed tomography is the imaging modality of choice in further evaluating tumor characteristics and expansion, treatment planning, and monitoring recurrence. Definite diagnosis of GISTs is based on the immunohistochemical study. Early diagnosis and complete surgical resection of the tumor yield good long-term outcomes. We present a case of a small gastric GIST which was early detected and treated and the patient has tumor-free during 8 years of follow-up.
