Non-epithelial tumors of the stomach (NTS) are a very rare type of tumor and account for 3-4% of all malignant neoplasms of the stomach, as well as 1% among tumors of gastrointestinal tract [5].

Non-epithelial neoplasms of the stomach are found in 60-70%, of the small intestine in 25-35%, in the colon and rectum in 5%. The clinical manifestations of disease depend on the location and size of tumor. Today, the main method of treatment for NTS is surgical treatment [4, 7, 8].
