A Case of Early Esophageal Cancer Associated with Invasive Thymoma / 대한소화기내시경학회지

Metachronous double cancer of primary early esophageal squamous cell carcinoma and invasive thymoma is a very rare condition. The invasive thymoma had been detected during the myathenia gravis evaluation and treated by radiation therapy 5 years ago. The esophageal lesion had a nodular-surfaced flat elevation at the mid-esophagus that was found by esophagoscopy. Radical resection for the lesions was undertaken after histologic confirmation. Postoperative pathologic examination documented that the esophageal squamous cell carcinoma was in the "early" stage involving the mucosal and submucosal layer only. We report a case of early esophageal cancer associated with invasive thyrnoma with literatures review.
