Gastrointestinal stromal tumor of the stomach. Case report

Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors of the alimentary tract. Nowadays GISTs represents 0.1–3% of all gastrointestinal malignancies, making it a diagnostic challenge. Lesions are frequently located in stomach and proximal small intestine but rarely elsewhere in the abd...
