摘要
目的探讨食管颗粒细胞瘤的病理形态、诊断、鉴别诊断及预后。方法回顾性分析我院2008年至2014年7例经病理诊断为食管颗粒细胞瘤患者的临床资料。采用常规HE染色及免疫组化法分析7例食管颗粒细胞瘤的病理特征及与临床资料间的关系。结果 7例患者肿瘤均位于食管黏膜下层,呈灰白至灰黄色,结节状,无包膜;直径0.4~1.0 cm。镜下：肿瘤细胞呈圆形、多边形或梭形,胞质丰富呈嗜酸性颗粒状,细胞核小,核仁不明显,大多位于中央,未见核分裂像。免疫组化：肿瘤细胞S-100、CD68和NSE阳性,SMA、desmin、CK、CD34、CD117、DOG 1、HMB45阴性,Ki-67低表达。组织化学：PAS阳性。7例全部为良性肿瘤,随访8个月至6年,无复发病例。结论食管颗粒细胞瘤是比较少见的软组织肿瘤,多位于食管中下段,绝大多数为良性肿瘤,预后较好,确诊依赖于病理诊断。
Objective To investigate the pathological feathers,diagnosis,differential diagnosis and prognosis of esophageal granular cell tumor. Methods The data of seven patients of esophageal granular cell tumor diagnosed from 2008 to 2014 in our hospital were analyzed.Seven cases of esophageal granular cell tumor were studied by hematoxylin-eosin and Eli Vision immunohistochemical staining,the clinical and pathological feathers were analyzed with review of the literatures. Results The pathological feathers of seven cases were very typical. The tumors located in the submucosa,and showed gray to grayish yellow,nodular,with no capsule. The size of these tumors ranged from 0. 4 ~1. 0 cm in diameter. Microscopically,the tumor cells were round,polygonal or spindle with small central nuclei and rich eosinophilic granules cytoplasm,the nucleolus could not be easily seen. Immunohistochemical stain showed that the tumor cells were positive for S-100,CD68 and NSE,but negative for SMA,Desmin,CK,CD34,CD117,DOG1,HMB45. The proportion of Ki-67 positive cells was very low. Histochemical stain showed that the tumor cells were positive for PAS. All 7 cases were benign,and the follow-up time was from 8 months to 6 years without recurrence in patients. Conclusion Granular cell tumor of esophagus is very rare in soft tissue tumors,most of which are benign and located in the middle and lower segment of esophagus. The tumor has a better prognosis. The definite diagnosis should depend on the pathological diagnosis.
