The lymphatic anatomy of the esophagus. Lymphatics enter the mucosa to lie just below the basement membrane of the epithelium and drain the lamina propria and muscularis mucosa. The submucosa is richly supplied with an interconnecting network of lymphatic channels that run the length of the esophagus. Lymphatics intermittently pierce the muscularis propria to drain into regional lymph nodes or directly into the thoracic duct. (Reprinted with permission from the Cleveland Clinic Foundation.)
