[Primary malignant melanoblastoma of the esophagus (author's transl)].

Clinical and morphological aspects based on the observation of one case of oesophageal melanoblastoma are discussed. We want to point out that the characteristic morphology of the tumor enables us to exclude melanoma metastases and thus give an exact diagnosis. The importance of oesophagoscopy for the preoperative diagnosis is emphasized; radical resection is recommended for therapy.
