Among benign esophageal tumors, leiomyoma is the most frequently seen and lymphangioma is extremely rare. This article reports a case of lymphangioma arising in the cervical esophagus.
A 74-year-old man complained of mild swallowing difficulty. Esophageal fiberscopic examination showed a submucosal soft mass with an apparently preserved overlaying mucosa in the cervical portion of the esophagus. MRI revealed a low intensity area on T1-weighted, and a high intensity area on T2-weighted images. The tumor was not enhanced on the T1-weighted image with gadolinium contrast.
The tumor was successfully removed under direct esophagoscopic control without any complications. Lymphangioma was diagnosed by histopathological examination. Postoperatively, the symptoms were resolved, and the patient has remained asymptomatic for 1 year and 10 months.
