Three cases of granular cell tumor of the esophagus are added to the 17 previously reported in the literature. These tumors, thought to be of neural origin, are difficult to diagnose preoperatively. The diagnosis should be considered in adult females presenting with an intramural mass of the proximal or distal third of the esophagus. Symptoms of dysphagia and substernal discomfort are likely to occur with lesions greater than one centimeter in diameter. Preoperative biopsy is not advised as a mistaken diagnosis of squamous cell carcinoma can result.
本文报告3例食管颗粒细胞瘤，加上文献中先前报道的17例，共有20例。这些肿瘤被认为起源于神经，术前难以诊断。对于成年女性出现食管近端或远端三分之一壁内肿块的情况，应考虑该诊断。直径大于1厘米的病变可能会出现吞咽困难和胸骨后不适症状。不建议进行术前活检，因为可能会误诊为鳞状细胞癌。
