Abstract: Abstract:objective: We analyse 12 cases of typical esophageal leiomyoma in order to improve the understanding for it. Method: There are 12 cases of esophageal leiomyoma which have been proved by operation and pathological examination from 1997-2007. Results: In the 12 cases, 7 are males, 5 are females. The average age is 39. The course of disease is from 3 months to 3 years. All patients have the foreign matter sense after eating and the pain behind sternum. One of them occurred in the ingress of esophagus, 9 in the middle-under part, one in the upside, one in the underpart. The sizes of esophageal leiomyoma are from 0.5×0.5×l.0cm to18×3.0×2.0cm. The shape of esophageal leiomyoma is round and half-round for 10 cases , one looks like dumbbell, one case has pediculus. Conclusion: Most cases have the typical symptoms of the esophageal benign tumor, but some special cases need careful observation, for example, the esophageal leiomyoma with pediculus and the esophageal leiomyoma occurred in the ingress.
