title: Primary malignant melanoma of the esophagus. A case report.
abstract: A case of primary malignant melanoma of the esophagus has been reported. This rare entity accounts for less than 0.2% of all esophageal neoplasms. A polypoid, deep blue and tough tumour was present on endoscopic examination during which a few samples were taken. Microscopically melanotic tissue occupied the whole submucosa and scanty deposits of melanin pigment were dispersed. Positive immunohistochemical stain with HMB-45 antibody confirmed the diagnosis of malignant melanoma. The patient was admitted to the Oncological Center for resection of the tumour, which is the treatment of choice in such cases.
