Is gastric leiomyoma serious

summary

Gastric leiomyosarcoma is a malignant tumor originated from gastric smooth muscle tissue. Leiomyosarcoma of the stomach mostly occurs from the muscularis propria of the stomach, which is rare. The clinical manifestations of X-ray barium meal and gastroscopy are lack of specificity. It is easy to be confused with gastric cancer, gastric leiomyoma and other primary gastric tumors. It is difficult to make preoperative diagnosis and differential diagnosis. Clinically, gastric leiomyosarcoma is not easy to be completely resected, and the prognosis of patients is poor due to the poor effect of chemotherapy. So, how to diagnose and differentiate gastric leiomyosarcoma? Let's get to know!

Is gastric leiomyoma serious

First: the differential diagnosis of leiomyosarcoma at the bottom of stomach and carcinoma of cardia: Leiomyosarcoma at the bottom of stomach has a soft tissue mass in the gastric vesicle, which is the same as carcinoma of cardia. Leiomyosarcoma at the bottom of stomach rarely involves the esophagus even near the cardia, while carcinoma of cardia involves the lower end of esophagus, which is the basis for the diagnosis of carcinoma of cardia.

Second: gastric leiomyosarcoma should be differentiated from gastric leiomyoma, gastric cancer and other non epithelial malignant tumors of the stomach, and the latter can be differentiated by pathological examination. Leiomyoma is generally limited, round, mucosa is more complete, bleeding and weight loss is rare, histological examination, no cell pleomorphism, no giant cells, few mitosis.

Third, X-ray barium meal examination showed that the intragastric type was semicircular filling defect with neat edge and sometimes umbilical ulcer niche in the center; The external type of stomach is characterized by compression of stomach, integrity of gastric mucosa and flattening of folds. Gastroscopy showed the characteristics of submucosal mass, and biopsy at the edge of ulcer was helpful for the diagnosis.
