説明

We reported 10 cases of esophageal melanosis. Seven cases were male, and the other three were female. The mean age of the patients was 58.5 y/o. All cases had no symptom related to esophageal lesions and the diagnosis of esophageal melanosis was made by endoscopic examination which was performed for screening or suspected gastric disorders. Endoscopic examination showed the flat lesions characterized by spotty, linear, band like, or patchy pigmentation with color of brown or black. The size of lesions ranged from 2 to 20mm. All the lesions were located in the middle or lower third of the esophagus. Histological examination of the biopsy specimen showed many brown granules in cells of the basal layer of the esophageal epithelium on H-E stein. Masson-Fontana stain and electron microscopic findings confirmed that these cells were melanocytes. The prognosis of esophageal melanosis and its association with malignant melanoma are still unknown, since there have been few reports of this lesion. Recent progress of esophageal endoscopy, including electronic endoscopy, will increase the chance to find esophageal melanosis, and prospective follow-up of many cases with this lesion will clarify the natural history of esophageal melanosis.
