[Differential diagnosis and analysis of 34 cases with esophageal and cardiac leiomyoma and leiomyosarcoma].

34 cases with esophageal and cardiac leiomyoma and leiomyosarcoma were treated by surgery from Nov. 1955 to Mar. 1988. Two groups, that of the esophagus and that of the gastric cardia were divided. The patients average age is 34.8-year and 51.8-year respectively. The shortest course of the disease is 15-day and the longest one is 12-year. Dysphagia had been the major symptom. 30 cases had single tumor and 4 cases had multiple lesions. Totally 41 tumors were resected, among which the smallest tumor is 0.6 X 0.4 X 0.3 cm, the largest one is 10 X 9 X 7 cm. Diagnostic criteria to differentiate leiomyoma from leiomyosarcoma and these smooth muscle tumors from other diseases were discussed.
