The esophagus was totally excised for histopathological examination in 276 autopsy cases and 66 surgical cases (total, 342 cases). Leiomyoma of the esophagus was observed in 27 of the 342 cases. The tumors were present in 22 of the 225 male cases and in 5 of the 117 female cases. There were 38 leiomyomas among the 27 cases. Most of the leiomyomas originated in the inner circular muscle. None of the tumors was more than 7 mm. in length. Twenty-five of the 38 leiomyomas were located in the esophagogastric junction zone. Thus, subserial histological examination revealed leiomyomas at a higher frequency than that in previous reports.
在276例尸检病例和66例手术病例（共342例）中，对食管进行了全切除以进行组织病理学检查。在342例病例中，有27例观察到食管平滑肌瘤。在225例男性病例中有22例出现肿瘤，在117例女性病例中有5例出现肿瘤。27例病例中共有38个平滑肌瘤。大多数平滑肌瘤起源于内环肌。没有一个肿瘤长度超过7毫米。38个平滑肌瘤中有25个位于食管胃交界区。因此，连续切片组织学检查显示平滑肌瘤的发生率高于以往报告。
