Primary malignant melanoma of the esophagus is a rare, aggressive and poor-prognostic neoplasm, usually detected in late stages. Surgery (esophagectomy) is the treatment of choice when operable and the only factor that improves the disease prognosis is the detection of the lesions in early stages and the recognition of non-typical lesions.
