Malignant melanoma of the esophagus is rare and its prognosis is extremely poor. We report a case of malignant melanoma of the esophagus.

 A 54-year-old man visited our hospital complaining of anal bleeding. Colonoscopy revealed an adenocarcinoma in the rectum. At the same time, upper digestive endoscopy was carried out and revealed a protruded tumor with pigmentation in the lower thoracic esophagus. The surrounding mucosa was also pigmented. Endoscopic biopsy of the tumor was diagnosed as malignant melanoma. The patient received chemotherapy and although the tumor has been growing, he is still alive.
