Gastric fundus intrinsic muscular layer hypoechoic foci mesenchymal stromal tumors are the most common mesenchymal tumors in the digestive tract, originating from undifferentiated mesenchymal cells, with the possibility of malignant transformation, and the treatment of choice is surgical treatment.
Gastrointestinal mesenchymal tumors can be single or multiple, varying in size from 1cm to 20cm in diameter, with a tough texture and a nodular surface. Hemorrhage and necrosis may occur during the growth of the tumor.
Different parts and sizes of tumors can also cause different symptoms, and some patients can have epigastric pain, bleeding and other symptoms. When the size of the tumor becomes large, a lump can be felt in the abdomen. Mesenchymal tumors may cause intestinal obstruction and jaundice if they occur in the intestines.
Surgery is preferred for the treatment of gastrointestinal mesenchymal tumors. For patients who cannot have surgery or have recurrence after surgery, imatinib, a tyrosine kinase inhibitor, can be used. If you feel unwell, please seek medical advice promptly.
