Mucosal bridge, endoscopically observed, is a cord-like mucosal connection across the lumen. The bridge is very elastic and stretches easily, unlike granulation tissue. Mucosal bridges of the esophagus have been occasionally described in various circumstances, particularly in congenital or acquired origin as the inflammatory diseases. The occurrence of mucosal bridges due to inflammatory process may arise anywhere from the esophagus to the colon. It has been more frequently reported in the colon than in the esophagus, stomach, and duodenum. We experienced four cases of esophageal mucosal bridges and three of them were accompanied by esophageal diverticulum. We report these cases with a review of relevant literatures.

Esophageal melanosis is discrete proliferation of melanocytes in the basal layer of the esophageal epithelium. Histologically, pigmented melanocytes lacking atypia and mitoses are observed amongst the keratinocytes in the basal layer of the esophageal mucosa. Junctional activity is absent. Esophageal melanosis has been reported synchronously with or preceding malignant melanoma and the possibility that it might be a premalignant lesion has been suggested. The value of sampling these pigmented lesions during endoscopy is emphasized as a means of obtaining well preserved material for the evaluation of a lesion which some authorities have viewed as a possible precusor for esophageal malignant melanoma. The management of esophageal melanosis consists of complete destruction of any isolated melanotic pigmentation by surgical operation, endoscopic electrocoagulation or laser. We experienced a case of isolated esophageal melanosis associated with benign gastric ulcer in a 63-year old man, who was admitted to our hospital complaining of hematemesis. Endoscopic esophageal mucosal resection (EEMR) was performed for the management of isolated esophageal melanosis.
