    Abstract:
    BACKGROUND & OBJECTIVE: Esophageal stromal tumors and smooth muscle tumors are not easy to be distinguished in clinic though they have different pathologic features. This study was to compare the clinicopathologic features of esophageal stromal tumors and smooth muscle tumors, and discuss their treatments. METHODS: The expression of CD117 and CD34 in 16 specimens of primarily diagnosed esophageal leiomyoma, 4 specimens of esophageal leiomyosarcoma, and 1 specimen of stromal tumor was detected by immunohistochemistry. The clinicopathologic features of the patients were analyzed, and the treatment principles and curative efficacies were summarized. RESULTS: Of the 16 cases of primarily diagnosed esophageal leiomyoma, 5 were CD117(+) and finally diagnosed as non-high aggressive fatal stromal tumor according to the assessment criteria of stromal tumors; 11 were CD117(-). The stromal tumor was CD117(+) and CD34(+), and diagnosed as high aggressive fatal stromal tumor. The 4 cases of primarily diagnosed esophageal leiomyosarcoma were CD117(-) and CD34(-). There was no obvious difference in clinicopathologic manifestations, treatment and prognosis between esophageal non-high aggressive fatal stromal tumor and leiomyoma, and between esophageal high aggressive fatal stromal tumor and leiomyosarcoma. CONCLUSIONS: Esophageal stromal tumors and smooth muscle tumors can not be distinguished with clinicopathologic exhibitions. The immunohistochemical examination of antibody CD117 is necessary for identifying them. Lumpectomy or esophageal partial resection is enough for esophageal non-high aggressive fatal stromal tumor and leiomyoma. Esophageal partial resection is necessary for esophageal high aggressive fatal stromal tumor and leiomyosarcoma.
