目的 :食管癌肉瘤是一种罕见病 ,通过回顾分析本组较大样本食管癌肉瘤的病理资料 ,分析其临床特点 ,以助诊断。方法 :对 2 0例食管癌肉瘤病人的临的床资料进行回顾性研究。结果 :食管癌肉瘤多为覃伞样、息肉样腔内生长 ,个别呈浸润生长。光镜下肉瘤与癌两种成份共存 ,瘤体以肉瘤成分为主 ,表面及蒂多分布癌组织 ,活检常显示为鳞癌。X线表现为食管腔内息肉样的充盈缺损 ,轮廓较为光滑整齐 ,粘膜显示“涂抹征”。结论 :食管癌 ,是一种低侵袭性的肿瘤 ,以腔内生长为主。临床表现与食管癌有一定区别 ,“涂抹征”是其典型的X线表现。食管镜活检多显示鳞癌或低分化癌 ,术前较难确诊。
Objective: Esophageal sarcoma is a rare disease, by reviewing the larger sample of esophageal sarcoma in this group of pathological data, analysis of its clinical features, to help diagnose. Methods: The clinical data of 20 patients with esophageal sarcoma were retrospectively studied. Results: The majority of esophageal sarcoma were tan umbrella-like, polypoid-like cavity growth, and some were infiltrative growth. Light microscopy and sarcoma two components coexist, the main sarcoma tumor components, surface and Tissue distribution of cancer, biopsy often showed squamous cell carcinoma. X-ray showed polypoid filling of the esophageal cavity defect, the outline is more smooth and tidy, the mucous membrane shows “smear sign.” Conclusion: Esophageal cancer, a low-invasive tumor, is predominantly intraluminal. Clinical manifestations and esophageal cancer have a certain difference, “smear” is its typical X-ray findings. Esophageal biopsy and squamous cell carcinoma or more poorly differentiated cancer, preoperative diagnosis is more difficult.
