A histoinmunohistochemical analysis showed the presence of a gastrointestinal stromal tumour (GIST), demonstrating diffuse positivity for CD117 (Ckit), focal positivity for CD34, and negative results for S100 and desmin.<h4>Conclusion</h4>It is critical to avoid tumour rupture during surgical resection, as this may result in tumour implantation or recurrence. The gene discussed is DES; the disease is gastrointestinal stromal tumor.
